I am going to connect two Catalyst 2948G switches, and I want to know what the best GBIC is to use to do so. A link to a cable I could order would be great, or a brand and model number.

I have a 892 router configured on fa0 with vlan1 and a catalist 3560. On catalist all ports are in access mode and vlan1. When I'm connecting port fa0 from router to catalist, the catalist port is shuted down What should I do on router on catalist to make the connection working ?
View 4 Replies View RelatedI added Linksys RV-016 16-ports VPN Router into the connection. RV-016 supported multiple subnets.
As mentioned in [URL], D-Link DIR-615 needs to be a device which could support multiple Vlan subnets. But unluckily DIR-615 does not support multiple Vlan subnets.
Therefore I added Linksys RV-016 in the the combination of devices. As what i found in RV-016 GUI setting, it supports multiple subnets.
Purpose outline:
1. Have to create two different SSIDs.
- SSID 1 for Management (able to view all other LAN devices)
- SSID 2 for guest and staff (unable to view all other LAN devices)
2. Create two VLANs in catalyst 2960s.
3. Create two subnets in Linksys RV-016 to accept two Vlans from catalyst 2960s.
Any experience of configuring RV-016 for the mentioned purpose above?
I bought refurbished Catalyst 2950. I followed all steps(even ip address and subnetmask and ..etc) guided in [URL] no thing happen, my computer doesn't connect internet. I guess switch has no routing.. Before bought that, i thought it is plug and play type. And now having some serious issue which i have to configure via telnet and/or ssh.
View 12 Replies View RelatedScenario: Two buildings connected with a private leased fiber line, so it does operate as a LAN. There are several subnets and everyone at both buildings needs to be able to access all subnets. However the physical machines on those subnets are building specific:
-Building 1: 10.2.0.0/24 (vlan20), 10.4.0.0/24 (vlan40), Internet connection
-Building 2: 10.1.0.0/24 (vlan10), 10.3.0.0/24 (vlan30)
The majority of the traffic between the subnets is specific to the buildings as well (i.e. most of the traffic is between 10.1 and 10.3 or 10.2 and 10.4).
Currently I have a Catalyst 3560 at Building 1 operating as the single "core" L3 router (and then a variety of switches connected to that). I have another 3560 at Building 2 that I'd like to turn in to the "master" L3 router for the two subnets primarily used by Building 2. In other words, make it so traffic from 10.1 to 10.3 doesn't have to run to building 1 just to get back to building 2.
I've got a basic knowledge of adding VLANs, VLAN interfaces and a static routes. The part that I'm getting confused on is that the Building 1 core router needs to make its default route to the firewall (and on to the internet) but "know" that traffic on vlans 10 and 30 gets sent across the fiber line to the other router. So I'm assuming this gets done with some combination of vlan definitions, vlan interfaces and static ip routes on each router.
I have got a new 48port Cisco catalyst 4948 switch, which I configured as a VTP client and connected to Cisco 3750 which is a VTP Server (this switch is on production network). I connected port g1/0/48 from 3750 to port g1/48 on 4948 through a straight cable and made both ports as trunk port (I also tried through cross cable). The problem is these two switches are not detecting. For testing I connected a PC directly to one of the port on 4948 (making that a switch port) still the LED on switch didn’t glow up. Is there any special command needs to be run on 4948 switches to activate its physical ports?
View 7 Replies View RelatedI have a Cisco Catalyst 2960 series switch. When I connect another switch or a VMWare Esx server on one of the ports, the port blinks for few seconds and then goes off. When I connect a desktop or laptop or a windows server the ports stay led and I can access resources on the network. However, when connect another switch or a vmware esx server, the port is disabled.
What config in the switch can I check to make sure the ports stay on regardless when I connect a desktop / laptop, switch or vmware server?

View 3 Replies View RelatedI have an interesting problem. I have a 6509 that I'm trying to swap the GBIC on. The switch is already using a GLC-SX-MM GBIC and it is up/up and passing traffic, but we are getting some errors and suspect it may be faulty.
I want to replace the GBIC with one of the identical model - a GLC-SX-MM. It was brand new, never been opened. When the new GBIC is plugged in the link light on the switch goes completely off (not amber) and the port goes into a down/down (not connect) state. There are no messages in the logs at all. It's like it doesn't even see it. If you plug the old GBIC back in then the link comes back up. I tried a different port with the same results.Thinking that the new GBIC may be faulty (even though it was brand new) I tried a second GLX-SX-MM, also new. That one does the same thing.
At that point I thought there might be a problem with that switch, so I tried the GBICs on the other 6509 in that pair. The other 6509 is running the same hardware and software. The GBICs will not work there either. If you move the old, suspected faulty GBIC from 6509-2 to 6509-1 then that it works.
The solution would seem to be that I have two faulty GBICs, but I'm having trouble persuading myself that I have two new ones, straight out of the package, that are both bad. Are there any other things to check on the switch? Here's the pertinent information:

I've inherited a network. It looks to have been setup as 10/100 originally, using Netgear FSM726S switches with fibre connecting the switches. The fibre to copper conversion is mainly achieved with 10/100 media convertors rather than GBICs - not sure why - though there are some GBICs in use. Some of the "key" switches have been upgraded to Cisco Catalyst 2960G switches, but nothing else has been touched, so most of the network still runs at 100MB.
View 1 Replies View RelatedThe switch has been set to Level 3 Routing. Port 27 has been in use as a Fiber Transceiver with no problems for several weeks. This week I tried connecting a second Fiber Transceiver to Port 28, and it would not work.
Swapped the physical GBIC modules in the ports, and the situation remained exactly the same: Port 27 works, Port 28 would not work.
Connected to the copper-part of the combo Port 28, it immediately connected and worked fine.
Connected an external Fiber Transceiver Box in place of the GBIC in Port 28, and it immediately connected and worked fine.
Swapped the new Fiber jumper (Port 28) with the existing Fiber jumper (Port 27), and the new connection came up immediately and worked fine. The existing connection would not work when connected to Port 28.
By "not working", I am not able to ping across the connection. The link light comes on and blinks. The transmit/receive statistics show as if data is processing on this switch, but on the other side of the Port 28 connection, the switch shows Transmit traffic, but no Recieve traffic.
Im trying to determine the serial number of Gbics already installed and running on a Catalyst 2950 switch. Is there a specific command to do so? There is a command on Catalyst 4506 that gives all info regarding the Gbic ("show idprom interface gi 1/1") Is there something equivalent for 2950?
