I have installed a Procurve 2530 j9773a switch for a customer. However when trying to add it to PCM it connects and successfully sees the SNMP community, however it then hangs on discovering devices. The software is quite old now, so my query is do we need to update the version of software or is there MIB like file for this switch we need to import before hand. If the software needs to be updated, does anyone know of a chart to compare which switch models are compatible with which version of update. Any information would be helpful.

I'm curious of the reasonings for using hubs when a switch is available. The network consists of HP servers from 2008 and HP business desktops with gigabit NIC's. There may be a few older machines running on the network that run XP but they have gigabit NIC's (these machines have older dot matrix printers running on them as local printers).

The network is setup with 6-8 servers running to a gigabit switch & switch is uplinked to 2 48 port Cisco Gigabit switches. There is a 48 port Cisco 10/100 hub as well that is plugged into one of the stitches with one cable and then one cable running from the hub to another system (reportedly a computer....)

What would be the benefit or application of using a hub attached to a switched network, especially when there is no need to have the hub in the mix (the cable plugged into the hub could be plugged into a switch as there are empty ports).

Can anyone give me any insight into why this may be set up this way? I've asked about what is connected to the hub and get very nebulous answers. It is clear that whatever is hooked up to the system is either used or monitored closely as disconnecting the wire results in its mysterious reconnection in a very short time period yet no one ever admits to reconnecting it. (they must also know to connect the hub to the switch and which cable was originally in the hub - there are no markings and all cables are identical looking).

From what I have seen it seems th... Read more

Answer:Hub broadcasting vs switch routing

You could throw something else on the hub and listen to the traffic. Maybe it's just bring used as a signal repeater? Other than that, I can't imagine a reason for it being there. The hub is just repeating the signal so if it's in the same IDF, your guess is as good as mine.

Hi All,

I would be extremely grateful to anyone who can solve this problem for me...

How is it possible to configure 2 VLANs to communicate with each other on the same switch? I have managed to create 2 VLANS and they both work (and can access the internet), but they can't communicate with each other.

VLAN1 has an IP range starting 10.4.160 and VLAN2 has an IP range starting 10.6.192.

Is it VLAN routing that I'm looking for? Are there any Netgear switch experts out there that can help me set this up? My switch is Netgear GSM7328FS.

Thanks in advance
Nick
 

Answer:VLAN Routing (Netgear Switch)

To allow routing between VLANs on the same switch, you need a layer 3 switch, which you have. I've never configured one of those. The only Netgear switches I've configured are the web managed ones which are layer 2 only but have configured other layer 3 switches. Basically, you need to create a VLAN interface and assign an IP address to it. By default when the switch has multiple VLAN interfaces with IP addresses, it will route between them without needing to have any static route entries or the use of routing protocols. It is known as locally connected. With the connected clients on both subnets, you would make the default gateway the IP address of the switch on that respective subnet/VLAN.

I need to start VLANing out an office network and have some questions regarding interVLAN routing.

The network consists of a L2/L3 Cisco 3560 as the core switch and about 15 Catalyst 2960's and 2950's plugged into it for access level switching. The network has 2 subnets and are not separated from eachother by VLANs or router interfaces, which has created a single (large) broadcast domain. Plugged into the core switch is a linux box that provides our routing. It has a single interface with 2 IP's bound to it - each IP is the default gateway of both subnets. Using this setup, I need to figure out how to implement VLANing and move the routing to the 3560.

Cisco has a good document explaning interVLAN routing for the 3560: http://www.ciscosystems.net.ph/en/U...s_configuration_example09186a008019e74e.shtml

I want to use the 3560 as the router now and phase out the linux box, but do so one subnet at a time instead of all at once. If I setup a 3rd subnet, a VLAN, and a VLAN interface for it on the 3560, can the linux box be the default route as suggested in the document? If so, it doesn't need to be a trunk port does it? That's only the case if the linux box does the interVLAN switching right?
 

Answer:InterVLAN Routing on Layer 3 Switch

What's at the edge doing routing? The 3560s won't NAT, so you need something that will.

Use a 3560 as your core, break the two subnets up into two (or more) VLANs and have all your hosts point to it for their defaults. Then point the 3560 to your edge router or the linux box as its default to the internets (no trunk port, either a routed port or a switch port in the outside VLAN). Use ACLs or a firewall on the edge device.

Currently I have experienced collisions and packet loss on an outer routing switch (1-2% from the States and above 6% when tested from Europe). In a basic way infrastructure looks like



Where outer switch is Netgear DS524 (previously some Linksys). NSA TS and NSA HA are Sonciwall 2400 family. Internet test gateway and WiFi are network devices before a firewall (a PC and a wireless guest AP).

I have tested if there are packet loss on VLANs behind a firewall but all work as should.

What can cause those packet loss on that outer switch? Any good suggestions for a hardware replacement (up to 8 ports, rack mountable)?

Thanks
 

Answer:Outer routing switch - collisions and packet loss

You shouldn't have collisions unless something is half-duplex, which should be very rare in this decade. Mismatched duplex is a silent killer.

I recently started using a gigabit switch alongside my TP-Link router.

My room is setup like a LAN area, with a desk long enough for 4 pc's, so I have 4 cables running from the switch to the computers.

My router is providing DHCP and has a PS3 and VOIP phone plugged up to it.

Is there anything blaring that would cause the machines not to transfer files at gigabit speeds? Currently they transfer at 10-12mbps, which is normal for a 10/100 connection.

Anything I'm missing?

I can get into a lot of detail, but I need to know what needs to be told.
 

Answer:Home Network Routing - Using a Switch for file transfers?

Weakest link in the chain prevails.

Code:

ISP=Router--switch-- PC{1+}
|
+--- other device(s)

Consider just devices attached to the router, the slowest Nic {wired or wifi} will control the bandwidth to the device. A PC with a 10/100 adapter dominate data to/from it regardless of the GB Switch. If PC.a and PC.b (both with GB adapters and attached to the switch) copy 'twix each other, you may get much better performance.

Data to/from other devices (attached to the router) will be dominated by the Router LAN port speeds or the devices themselves.

99% of us get no benefit whatsoever from GB routers or Switches as all devices need GB ratings :sigh:

Hello again all. I've been pondering something for a while.

I have a SBS2003 server at work and I use the Windows VPN to work on our database and such from home. The VPN itself works very well. I noticed something that made me think though. When connected to the VPN, all web traffic from my home computer gets routed through the server at work.

I know this is probably the fundamental idea behind VPN tunneling, but it makes things quite slow for me since I have lower bandwidth at work than at home.

Is there any way to route traffic with a VPN connection to work so that only the traffic that needs to access resources at work (Windows file shares, Sybase DB connections, etc.) goes through the server at work?

If you don't believe me or are confused, here's a tracert from my home computer when connected over the VPN:

Answer:VPN Routing Question

This is called split tunneling if I remember correctly, and alot of VPN concentrators don't allow it. I am not sure if SBS does or not.

EDIT: Why is traffic reaching your gateway so slow? You shouldn't have a several hundred second ping to your gateway.

Question: routing question

I'm not much of a router guy. I've heard the solution I'm looking for is "source based routing" but I haven't been able to locate any information that's useful to my current predicament.

Here's the situation:

We have our servers on 172.16.0.0/21.
Everyone else is on 172.16.8.0/21.
I have a Cisco ASA 5520 currently providing NAT with a local IP of 172.16.0.6.
I am putting a content filter in place.
All machines (including servers) currently have the core switch (HP 9304) defined as their default gateway, which in turn has the ASA 5520 defined as a default gateway.

How can I filter the workstations without filtering the servers?
Is anyone familiar enough with the HP 9300 series switches to tell me that it supports the necessary commands to establish a source-based route (workstation subnet routed to content filter)?
Would I be better off trying to do this type of routing in the ASA instead of the HP 9304?

Thanks!

Port forwarding is done from WAN -> LAN. All internal LAN traffic is not affected by it.

they have a dsl modem going to a Linksys router to a 24 port switch then to a little 4 port switch. sure, so then Would it be modem to router then router to any port on the big switch or is there an uplink port on the big switch it should go to? then you would hook a cat5e from one of the regular ports on the 24 port switch and run it to the uplink port on the 4 port switch need to no if the whole sequence is right. Hope someone can help, john will told me the cable would go from the big switch to the uplink on the small switch but I am wondering if I have it all right or not and wonderiing about from the router to the 24 port switch does the cable just go in a regular port in the big switch or if there is an uplink port does it go there. Hope you can understand my rambleing here.

Router to uplink port on 24 port switch, and then normal port on the 24 port switch to uplink port on the second 4 port switch. An auto-MDX port on a device negates the need to worry about uplink ports for that particular cable connection.

I'm trying to design the network for a class / lab environment, and I'm in over my head.

I need an isolated VLAN for each student team. Each VLAN would contain identical configurations, with an identical set of VMs occupying the same IP range in each VLAN. But I also want each team to have access to a common subnet with a common file share, shared hardware equipment, etc.

I thought we could insert a router (probably implemented in a VM) between each VLAN and the common subnet. That would let the students reach from their VLAN to the common subnet. But routing back from the common subnet to the individual VLANs would be a problem, since all VLANs use the same IP range.

Would it be possible to have each VLAN's router map (via NAT or whatever) the VLAN's IPs into a different range, so the common subnet sees a different IP range for each VLAN?

For example: common subnet is on 10.0.0.*. Each VLAN is on 10.1.1.*. From each VLAN you can access your own IPs at 10.1.1.* and (through the router) the common subnet on 10.0.0.*. Now let's say the router maps VLAN X into 10.0.X.*, so from the common subnet you can reach VLAN #1 at 10.0.1.*, etc.

Even better if we could have one router VM with 7 VNICs, with 1 VNIC on the common subnet and 6 on each of the 6 VLANs, doing the kind of IP mapping described above.

Does that make sense? Is it possible? Or is there a better answer?

Thanks!!

I'm wanting to upgrade my network to Gigabit.

Something that's always remained a mystery to me is if let's say my router has 10/100 ports that I attach to a gigabit switch. I have two computers with gigabit cards connected to the switch and I want to transfer a file between them (on the same subnet of course).

Here's where I get confused, and admittedly I don't have much more than basic TCP/IP knowledge. If I initiate a file transfer between the two machines, do the packets flow through the router for the entire transfer or just on the switch matrix itself? Would the router which is only running at 100mb be a bottleneck, or do the packets just flow on the switch giving me true gigabit speeds?

The PC's will talk directly to one another. The switch will have both PC's mac addresses in its mac table.

Ok. I'm looking at a little project for multiple gateways of last resort as kind of a fail over to the internet. Everything thus far that I've read says that you can do it and do it based on metric.

ex:
ip route 0.0.0.0 0.0.0.0 10.10.2.20 5
ip route 0.0.0.0 0.0.0.0 10.10.2.21 10

The down fall to this is that if the device currently connected does not go down but the connection does the next ip route is never used.

What I'm wondering is what could I use as a routing protocol that would sense the the first connection to the internet has failed and now needs to move to the next connection?

Here is a little visio of what I'm thinking. Any thoughts or is this not possible even?

Edit: sorry for lack of visio info, but the pix 506 of the left loses the connection to the internet but does not shut off, the cisco 3550 needs to move on to the pix on the right to get out to the internet now.

Rip or OSPF could be options, but I'm not sure what the Pix supports since I've never configured any for dynamic routing.

Let me preface by saying I have minimal knowledge when it comes to Cisco IOS,Cisco Routers, or linux.

What I'd like to know is, is it possible to configure a Cisco router in a way that default routes all traffic *except* certain subnets to an alternate default gateway?

This is the current setup - A client has a Small Business Server 2000 system that is currently configured to divert traffic destined for 10.200.6.* and 10.213.161.* subnets to a cisco router (already behind the ISA firewall and on the local area network) which connects them to their branch office and a transaction processing facility. I believe they have a 2500 series router.

What I would like to be able to do is have the client machines use the Cisco router as their default gateway and divert all traffic *except* the aforementioned subnets to the SBS server since the SBS also handles their DSL line for internet traffic.

Make sense? I'm not asking how one would configure the router since I do not possess the necessary experience to do so and I'll either subcontract someone to do it or have the transaction processing facility perform the configuration for the client.

I'd be open to other suggestions with the notation that this is truly *business critical* environment and requires %99.999 uptime during normal business hours.

um, it looks like your routers can't talk to each other. Both of your serial interfaces should be on the same subnet or a point to point /30 network.

Somethin like this:

Hey all! So I have a network question I'm hoping somebody can shed some light on. I've recently set up 2 routers w. Tomato firmware. The 2nd is setup as a wireless ethernet bridge and I have an htpc and xbox hooked into it. The 1st router is the DHCP router and i have my main rig and cable modem hooked into that one.

So question:
When the htpc runs tversity and streams video/music to the xbox, is the traffic going wireless from router 2 to router 1 back to router 2 (wireless speed) to the xbox or is it going from htpc to xbox all within router 2 (wired speed)?

I ask so I know if I should set tversity's video quality settings to reflect wifi tx speed or wired.

I created a paint diagram of the network layout but can't upload it right now. I'll do that when I get home from work.

Thanks!

I'll start out with yes, this is part of a lab implementation assignment for school. I've been looking aroud the web and checking the Cisco docs and I'm unable to find any thing that matches what I'm looking at so I turn to the [H].

Current setup requested is (some hardware removed for simplicity sake):

ISP Network =[1]= Internal_network =[2]= Cisco 2600 =[3]= Remote Network =[4]= Pix =[5]= ISP network

Professor has told us that part of the test of the network will be breaking link 3.
So where the remote network was able to connect to the Internal_network via the 2600 as the default route it will now need to connect through the ISP network.

Problem is how to do this with the only equipment at the remote site being the PIX? Floating static routes only seem to work with the Cisco routers not the PIX... what other options can we (my group and I) look into to solve this? As far as I can tell it's not possible without a router of some type, the PIX is just not capable of this...

I'd prefer suggestions of things to look at instead of direct answers, but will take any help at this point.

Hello,

I was currently assigned by my work to set up a small server so they are able to backup their files in one central location. I am using a simple IBM computer that will be fitted with an external hard drive that will act as storage for their back up files.

The ISP we are using is provided by the schools (we are in an external building that the school owns). Networking between the 4 computers have not been the issue so far. There is a rather large network box located on the other side of the building (away from the offices) and distributes wires to several locations. One wire in particular is connected to a 4 port hub and distributed between 3 computers. I had to redirect an existing wire from another location to feed another computer along with the server.

Computer 4 used to be placed on a desk by the front door where the old network jack used to be placed. But because of issues with staff accessing the computers other than work related (e-mail, goofing off, etc.) I opted to have the computer moved to the office so it may be under some sort of supervision from the Assistant Director. So I had to relocate the old box to a new location. (I had no way of running another wire from the hub over the walls to the other side of the room where (See Diagram) the new box is located.

I made a diagram to get a better understanding:

crypto map outside_map 30 match address 85

here is your problem.
outside_map 20 has a higher number than 30, so it gets checked first. In the cryptomap for 20, you are telling it to send alll traffic from 10.10.1.0/24 to ANY dest out this tunnel. Because of this, it never gets to the map 30.

It sounds like you either need to make access-list 90 more specific (i.e., don't include 192.168.0.0/16), or move 30 to a number less than 20.

Hi.

I have a standard connection, all connected up using another cisco device 1800 series.
But, well, I'm doing some lab training, and well, im used to using linux as routers, and my cisco skills isnt the best in the world either.
just tired of big boxes doing the routing, and planning to switch it out, but the 1800 is used as a switch >_< and testing out on the old 831 first.
ios running on the 1800= newest.
ios running on the c831= 12.3
The scenario is:"System image file is "flash:c831-123-7.T6.bin"

Modem(Bridge)->Router(C831)->devices.
192.168.2.253 192.168.1.1 dhcp range 192.168.1.100-200 excluded others.
I connected 3 devices, a wlan access point, a "server" and a computer.

If i want my server and access point to utilize the dhcp service and to get a ip like 192.168.1.2 for access point.
192.168.1.10 for the "server"
and the computer will get a dhcp whitin the dhcp range 100-200.

How to i configure dhcp leases to a specific mac address to be 192.168.1.2 and such on cisco routers?

2nd question, how to route so my modem is able to be connected inside the nat using C class ip ranges.

IT gets pat, nat, dhcp, wan, lan, dhcp range, ssh all that have i configured up.

alright, pertinent details

(ips changed blah blah)

main network is 192.168.1.0/24
increasing wifi coverage, need to setup DHCP(no dhcp currently, dont ask, not my call)
would like to do this on 192.168.2.0/24


I have a cisco 2911 at .1.2
and a fortigate 60c at 1.4

the 60c sits between the network, and the internet doing its job as a UTM and handling a few P2P vpn's, the cisco has some T1's to other offices into it

I gave the fortigate a secondary IP of .2.4 and set a DHCP pool on the internal interface to hand out .2.100-.2.150

it will not work. the 2911 has a 0.0.0.0/0.0.0.0 route that points to the 60C, I added a route in for 232.0 on it to point at .1.4 as a test and it did not help.

the 60c and 2911 are not directly connected, but both go to the same switch

the device that I am trying to get DHCP is attached to a different switch, which is on a 10gb link to the other one. if I put DHCP on .1.0 it works just fine so its not the 60cs dhcp server just not working.

I am just missing something. and I am not sure what

its making me feel very silly. if it was easier to do so I would just give all my .1 stuff a subnet of .254.0 but since its about 150 devices on static ip's thats a huge undertaking I am trying to avoid(and I think that would fix the issue?)
 

Answer:routing/subnetting question with DHCP

you will need to use an ip helper address in order to provide dhcp to another subnet because a couple steps in the dhcp process uses broadcast and broadcast traffic does not get routed.

Answer:routing question access lists..

I hate reading problems! But here's my lame-assed attempt at it.

I do not grasp your definition of management without the appropriate subnet mask. Is it a single management IP or a range? It is not clear what the range is and any possble solution is minimally impacted by it. In one spot you say management hosts and in the list you designate the management host, singular.

The explicit deny is not required but I like to include them as they are easier to think about when you see them in print. You also did not say what the default action was and it will, therefore, be denial of access.

access-list whatever permit tcp any host 172.16.0.1 eq www
access-list whatever permit ip 172.25.I-dont-understand somemask-to-go-along-with-this 209.0.0.128 0.0.0.127
access-list whatever permit ip 172.25.I-still-dont-understand somemask-to-go-along-with-this 209.0.0.0 0.0.0.127
access-list whatever deny ip any host 198.0.0.1 (or deny ip any any as is the default implicit which would include this)

I setup my OpenVPN server and client to send all traffic through the VPN tunnel instead of just the one subnet. Now when i do a ROUTE PRINT to see the routing table on my computer something strange is going on that I don't understand. I am connecting over my tethered phone and for some reason the default route is the ip address of my phone, then the next line it has another default route going out over my VPN tunnel but it has a 128.0.0.0 subnet mask. I don't get that? Can somebody explain this to me, i assume the second default route overrides my phones?

also the 192.168.2.0 route for the network i am connecting to is listed also but if all traffic is setup to be routed through the tunnel why does it need to add that route?

At work I have managed to get hold of a test server to play with a GL230P

The server is running Windows Server 2008 64 bit and I will be using VM Ware server to run virtual servers running Exchange 2010 as well as BES, sharepoint.

My first task is to Run Exchange and Blackberry Enterprise server and get real devices running on a real domain.

The problem I have is network access.

The only access network wise is via a USB adapter connected to a wireless network which is firewalled back out to the internet. I can get out fine but there is no rules or NAT to allow port forwarding. At this point getting direct external access to the server is not possible.

This means that running exchange is a no go at the moment as there is no way to route SMTP traffic from the WAN to the box that will be running exchange.

However I do have unrestricted access to an internet connection from home I was thinking of somehow tunneling through the internet to my home network using some form of VPN solution. Then using the internet connection from home to collect SMTP traffic. I could register a domain and point the MX records at my home connections IP. Router port forwards to the internal IP which would be the server connected via VPN

Is what I'm trying to do even possible? If so how would I go about it?

Thanks

Chris

Answer:question about windows server 2003 and wireless routing

Not a problem. When setup is complete for SBS you will just run the Internet Connection wizard and choose which NIC you want for your public interface and which you want for local interface. Pick the wireless for public and the hardwired for local (or vice versa I wasn't sure which you wanted). Then the internet will come in through the server and provide access to everyone else. It will do the routing, firewall, etc. SBS is soooo easy to setup. Just remember, do it the way IT wants to do it. Don't get in and mess unless you know what you are doing because its almost all wizard-driven and you don't know what its doing.

we have a Lanier 2135 (i belive) that does network scanning.

Basically, you set up the scanner/printer/copier/coffee maker/jukebox on the network.

Then install the management software on a computer that will never be turned off (server), then the software should be able to find the scanner via broadcast/responce, and establish the connection.

Then you should be able to assign a directory on the network where the management software will dump the processes scans.

Normally when something like this has happened to me I can reboot the PC and it will resume the installation. This time that was not the case it posts, then goes to a black screen with a white blinking underscore for about 40 seconds like its trying to access my DVD...then the screen goes blank completely. ALT f4 wouldn't work and it sat there for a period of time...SO option one...I did some things in BIOS so I restored it to default....to no avail...

Every time I try to print anything, my WF-2530 feeds a sheet through and reports paper out. The unit has seen little use and has never had a paper jam. I have carefully loaded only a few sheets of regular 20 lb paper and it does it every time. I have done the same with some Kodak photo paper for inkjet and gotten the same results. It simply does not detect that there is paper loaded.

I have tried resetting the unit, powering off then on, disconnecting and reconnecting the power cord. Nothing causes it to recognize that paper is loaded after it feeds the first sheet through. Press the 'OK' button and it will feed another sheet and continue to report 'paper out'.

I don't want to replace such a lightly used printer. If I can correct whatever is wrong with the paper sensor it would be a blessing. Help!

My question is this, is there a service out there that will point a static IP to a dynamic IP? Much like services like DynDNS.org but for IP's.

Hi,

I am searching for a solution at a networking problem:

Like a router, where there is a DHCP server on the router,
I need a 12, 16 or 24 port switch that is able to assign specific, preconfigured IP address to each individual port.(ie 192.168.0.1 to port 1 via DHCP protocol, 192.168.0.2 to port2, so if I plug a DHCP client device into port 1, it will get 192.168.0.1 as its address, plug the same device to port2 gets 192.168.0.2)

The switch also needs to be SNMP capable for monitoring, so it's probably going to be a managed switch.

Anyone know of a solution? please let me know.
 

Answer:Switch question: per-port DHCP question

I don't think you are going to get exactly what you are looking for as I don't think it's possible. The only thing I can think of is to create a VLAN for each port. Then use an IP helper for each VLAN.

Hello. I currently have a home network as follows.

3 PC's connected to router.
router connected to cable modem.

I would like to increase the througput on my LAN (amongst the 3 pc's) so I'm thinking about adding a switch such that it would be [3pc's->switch->router-cable modem]. I was wondering whether adding the switch would actually improve the LAN thoroughput or is this just adding unnecessarily repetetive. I am aware of the "7 layers of the osi model" of networking but am wondering whether switches and routers work on the same layers. Im assuming NO because router bases routing based on IP address while switch will deal with the MAC addresses (am i correct???). Since a switch will perform less inspections on the packets (IP filtering, SPI, etc..) am I going to get better results when adding the switch??

BTW, my router: SMC2804WBR
Switch i might add: Gigafast Mini Switch EZ500-S
 

Answer:To switch or not to switch? That is the question.

Your router has a 100Mbit switch in it so unless you are getting a gigabit switch and your PCs have gigabit interfaces you will get no significant boost in network speed.

You may get a small speed inrease if you buy a good 100Mbit switch - the ones integrated in home routers tend to be the bottom of the barrel type - this will give you some extra under very high loads.

What is a "good" switch? You would want something with crossbar fabric and/or cut-through packet forwarding (those are expensive).

Answer:Switch Question?

Hi Stik62
That's not very reassuring to hear. I'm of the same opinion, that "switches" are usually advertised as being capable of isolating the port which is causing trouble. Try to duplicate the problem on a different switch-port. By swapping the port and duplicating the problem you are trying to prove that the original port has hardware integrity.(not broken). If the port's not broken, then the Techs at Cnet woulf love to hear the details. It'll help them build better boxes.

It has the usual buttons at the top including a PC switch off button. So last night instead of the usual Start/Turn Off
sequence I used the button. PC immediately switched off with no saving settings etc.
I wondered if I might have lost anything, but switching on the usual way just now the PC went straight into fully booted
with no boot up sequence and everything loaded.
So question is what mode does it go into via the keyboard and is it a risky manoevre.

Thanks.

Hey guys,

Ive got one monitor that i would like to share between my laptop and my other PC. When i use it with my laptop id like to use it as a 2nd screen and with my pc id like to use it as the main screen.

I bought one of these:

CBL-102U 2-Port Mini KVM Switch with Cable

I connect the main adaptor (or the box) part to the shared screen. Then i hook one end of the VGA cable to my laptop and the other end to my other PC output..right?

I turn on my laptop and the screen and try the screen setting to extend monitor but nothing. Also tried using the function key on my laptop with the screen switch button - nothing happens

The only thing i get is a red flashing light on the PS1 light on the box, thats it. Do you need to have the PS mouse & keyboard plugged in order for the VGA to work??

Thanks

You would go out of the shared monitor into KVM and then out of the KVM into the laptop's VGA. And Into the Desktop's VGA. And Yes, the USB Keyboard and mouse must be plugged into the KVM and the output would go to the laptop USB as well as the Desktop USB. The USB has to be plugged in for everything to work.
Once you switch the KVM to the laptop, Then you have to adjust the Display to Extend Desktop.

Ok, I have a weird problem and it may sound simple to some. I have a laptop, Xbox 360, and sometimes a desktop (when I am repairing one) that I need to hook up to one monitor. I figured a KVM switch would be perfect but it gets its power from the USB/PS/2 port. Therefore, I am unable to use it as I will not be sharing a keyboard or mouse. I am unable to find one that actually has a power adapter (unless I overlooked it). I tried searching for a VGA Switch/splitter but I have only found one that would allow me to do what I need to do and the rest only allows you to connect one device and 4 monitors. Could someone recommend a cheap (under $75) KVM that has a power adapter or inform me of what I need to be looking for (like the correct words for the product that I need). Thanks in advance.

I have two computers at home. One's my daughters and I have no need for them to be networked. I'm using comcast cable for internet access.

What are the requirements for Fedora 7, because the computer I plan to run it on isn't that good, but it runs well enough.
 

Answer:One question before I switch...

Hardware requirements:




Fedora 7 requires an Intel Pentium or better processor, and is optimized for Pentium 4 and later processors.

* Recommended for text-mode: 200 MHz Pentium-class or better
* Recommended for graphical: 400 MHz Pentium II or better
* Minimum RAM for text-mode: 128MiB
* Minimum RAM for graphical: 192MiB
* Recommended RAM for graphical: 256MiB

6.3.1.2. Hard disk space

The disk space requirements listed below represent the disk space taken up by Fedora 7 after the installation is complete. However, additional disk space is required during the installation to support the installation environment. This additional disk space corresponds to the size of /Fedora/base/stage2.img on Installation Disc 1 plus the size of the files in /var/lib/rpm on the installed system.

In practical terms, additional space requirements may range from as little as 90 MiB for a minimal installation to as much as an additional 175 MiB for an "everything" installation. The complete packages can occupy over 9 GB of disk space.Click to expand...

In reality however - especially if you use Gnome or KDE - you'll get much better usability with 512 MB RAM, the more the better.

I have dsl router going to a dell gigabit switch and in one room I have a hub (because I ran out of jacks) and the everything in that room has a ton of problems.

If I get another switch to replace the hub, will it hand out IP's (i am running DHCP through the router) or will the router be able to manage both switches?

Are the dell switches any good? They have an 8 port for $54.
 

Answer:Hub or Switch Question

Sounds like you may be getting some collisions on your hub, going to a switch may more than likely resolve your problems, but I would look to see whats causeing the problem to begin with. Disconnect one machine at a time and check to see if your problems persist. It may be one machine broadcasting traffic that's killing the whole segment.

Hubs broadcast traffic to every device that they are connected to, switches only broadcast to the machine that is intended to recieve said info.

I have simplified this greatly, but I would never, ever, never again use a hub after moving to a switched network.

Just my 1/2 cent on this.

Question: Switch Question

Seeing how switches themselves do not have MAC addresses, when a computer on one switch wants to communicate with a computer that resides on another switch, wouldn't the 1st switch forward that frame to all nodes on it's own switch and then subsequently forward the frame to the switch with the computer with the frames corresponding MAC address? Seems to me that a switch would work like a hub in this type of scenario. Or does each switch have some sort of built in forwarding table?
 

Answer:Switch Question

In general switches (unmanaged/dumb) don't have MAC addresses unless they are managed or a layer 3 switch.

Yes, if the switch receives a frame with a destination MAC address it does not know about, it will forward that frame across all its ports. The chances of this happening is minimized as many computers/servers/devices will at least generate some traffic when it is first plugged into the network. When the particular computer/server/device generates traffic the switch will learn about the MAC address on that port. As you've said, once the switch has the MAC address in its MAC table for which port that MAC address resides on, all traffic will be directed to that port for that destination MAC address.

No, the switch is just broadcasting for this specific scenario. There are also ARP broadcasts which get generated by clients when there is a who is ARP request. Even when there is a broadcast like this, the reply message from a device will not be broadcasted across all the ports. The other thing that makes hubs hubs is how they function electrically. They act as a splitter. So the implication of this is that the devices connected to the hub HAVE to run in half duplex. Half duplex operation allows CSMA/CD to run which is the spec in ethernet to allow for collision detection. The way ethernet operates is that a device will listen on the wire before sending a frame. If there is traffic already on the wire, the device will wait a random amount of time before checking to ... Read more

if a managed switch say a dell or cisco support ACL's.. will ACL's do the following?

Here is what I want to accomplish.

24 ports assuming a 24 station lan.
2 gigabit uplinks so 1 server feeding 24 stations

server running services on ports (to be determined later)

I want to effectvly block the ability of ANY station broadcasting ANY service on ANY port that I decide.

So basically, station 1 is unable to run service A on port #X, but station 1 is also unable to run service B - Z on port #X aswell.

Will managed switch with ACL accomplish this goal for me?
 

Answer:question regarding managed switch and ACL's

Kinda sorta... you could block certain computer from seeing anything from a specific TCP/UDP port if that's what you want - if you knew the specific port or range. You can also disable multicast and other network features if you wish or block specific computers from being able to send data on specified port(s), only receive, etc.

Keep in mind that if you want to run an ACL and keep up with enterprise, learn CISCO or grab a DELL. The DELL ACL language is very similar to CISCO, it merely shortens some of the syntax.

Every machine on a TCP\IP network must have a unique IP address regardless of whether they are connected to a hub, switch or peer to peer. Using the same addee for more than one machine will cause an error and the second machine attempting to load TCP\IP using this address will fail to load the IP stack.

The standard IOS password recovery procedure simply lets you boot without loading the config. You then enable yourself, and copy the config into memory, change the password, and save the config.

The procedure for the 2900 seems similar..

I can get a Dell 5224 for under $400. Its a 24port managed, all gigabit switch. The plan is to use it with 12 Dell 2324 switches(24x 10/100, 2x 1000, dumb switch) connected using the two gigabit ports. This would give the lan, 83Mbits per user, should be more than enough, there is no reason to ever be able to saturate that. (Current lan just employs two 2324s)

I plan on using the 5224 to vlan each 2324 and setting up routes so only the services I want can take place across the lan(Limits the spread of virii, port scanning, hacking, games get high priority, filesharing gets lowest priority(except to one of the official fileservers that host the patches and such), etc).

Is this the correct route, or should I be considering other alterntives?
 

Answer:Managed switch question...

Just remember you have to go through a Layer 3 device to route any traffic between VLAN's. The 5224 is Layer 2. All the traffic will not be able to communicate with each other unless it goes through a Layer 3 device (VLAN-capable routers are Layer 3).

Good luck with the VLANs though. I could never get them to work properly on the 5212 or 5224. The one time I got them setup properly, the switch failed (and died) 2 months after I finished the config. Dell support is useless when it comes to networking issues.

I was not impressed with that aspect of an otherwise good switch.

I'm not sure what you mean when you talk about routes and priorities. It almost sounds like you're wanting to do full QoS, which the 52xx series will not allow you to configure. VLANs are going to allow you to create separate logical networks for traffic, they dont allow you to prioritize traffic on their own.

At work we have Ethernet at each work desk. This was fine for my one computer. But now I share my workspace and customers were asking for wireless when they sit in the showroom.

So here is what I did.
- I ran the ethernet into the proper connection port on back of switch.
- Ran 3 lines from the switch to 3 computers in the room. (hardwired)
- Used the 4th port on switch to give the wireless router a line for wirless broadcast.
This is perfect for me..... all the connections work fine.

The only problem is that using the Netgear instructions to reach the configuration menus does not work. I think it has something to do with the fact that the router is not using the line directly from the wall..... instead fed from the switch.

I tried to eliminate the switch altogether...... but for some reason when I plug the router directly to the wall all the computers on my network disappeared. I tried Public, Home and Work. But no other machines in our office would appear. This did however allow me to reach the configuration menus on the router.

Is there a way to access the router menus even when its getting a line from the switch?
I just want to be able to configure it on the fly..... instead of having to reconfigure the wiring just to get in to the menus.

Answer:n00b switch question

Well first, don't set ANY of that manually. The router should assign you all the IP info. If that's not happening, DHCP is screwed up, or else you have a bad cable or bad port.
If other PCs connected can get dynamic info, so should you, or setting static info won't help.

Try a new cable, and a new port. Make sure your NIC settings are all set to auto, and make sure you don't have firewall software interfering.

Good luck!

Sorry for the newbie question, but I'm just getting into more networking at work so this should be an easy one. When it comes to 24 Cisco/3com... switches, what is the standard for when to use a crossover and which needs to be an uplink?
 

Answer:Switch/uplink question

In a typical setup a cross over cable is not used at all. In fact it's possible the uplink port is unused as well, but it's fairly uncommon these days.

Computers would plug into the switch using patch (straight through) cables. Any modem or router would plug into it using the uplink port. Typically speaking you'd also use a patch cable for this connection, although sometimes (older models usually) will require a cross over cable to do this.

On a normal switch today a corss over cable is basicly only going to be needed if you are connecting the switch to another switch.

Hi, and thanks for taking the time to look over my question.

My father runs two towers through an 'IOGEAR' KVM switch. Both systems are Windows XP Home, SP3.

It appears that the KVM switch might be causing some issues and I thought he should disconnect the switch, re-boot and reconnect it. I did have him look through his Device Manager, but he was unable to locate anything related to the KVM switch.

I thought we might try and uninstall any drivers, then re-boot and have Windows re-install a new one. I don't believe the switch even came with any drivers, and it ran using the Windows drivers from the beginning.

My question is: Can somebody tell me where I would find the drivers within the Device Manager? (Under which category?) I'm guessing that it might be under the Human Interface Devices, but if anybody knows for sure and how I can identify it, that would be great.

Jumbo packets are nice, but you have to run them on your whole network, otherwise it will just slow everything down with fragmentation.

Not all traffic is unicast...

If the switch doesn't know the dest MAC, it will flood it out all ports. Some things (like the Windows Network Load Balancer in certain configurations) will spoof their MAC addy, so it never gets learned, and packets to the NLB will always get flooded out all ports unless you teach the switch.

What speed are your hard drives in your servers, and your controller card. Im assuming your servers are some form of SCSI. 160, 320?

Are you serving up anything else other than static webpages? Do you have any big databases that programs pull from? Multimedia?

The reason I ask is because is because most SCSI Ultra 160 drives out there are going to transfer data anywhere from 20MB/Sec to 50MB/Sec. It depends on your particular drive and where that data is on the platter and what (if any) RAID type you're running. I've seen 320 drives than can transfer as fast as 80MB/Sec, but I'm sure there are faster.

100Mb Ethernet=12.5MB/Sec (Theoretical Max)
1000Mb (Gig)Ethernet=125MB/Sec (Theoretical Max)

So dont assume that just by getting GigE you're going to see a massive performance increase hitting your servers. Its going to come down to the hardware on those servers and your access patterns. If you're running old stuff and just serving up 50-100kb websites all day long, you'd probably be better off going with 100mb and perhaps doing Link Aggregation across two links or doing DNS load balancing IF you need it. Your bottleneck here is probably going to be the server, not the network. Having GigE to the servers will however make sure that all the data requests make it to the server (in the case that 100Mb ethernet would be ... Read more

Hi everyone:

First of all - I am a real novice at networking but am learning fast so feel free to laugh.

I have a question about a networking situation I am doing within my computer lab at my school. (Systems running W98 and 95).

I have a 24-port switch and have my system as well as 21 of my total 24 systems hooked successfully to it (one of the ports in the switch is bad!)

I have three more systems that I'd like to get hooked to the network. How would I go about doing this? Would I need another switch? (Perhaps a simple 4 or 8-port)? If so - how do I connect a switch to a switch?

I'm learning quickly - made my own CAT5 cables last week. That was fun!

Thanks for any advice.
