Replacing WS-C2924-XL-EN with New Switch

[mmoore]

We have a switch that is End of Life soon and need to replace it. What is the current equivalent model to replace this switch. The switch is used for VLANs. The configuration is below. I would like to just keep things simple and use the existing configuration.

Thanks.

Hi,

Cisco Catalyst 2960.

Check the options for this family because there are differences in number of ports and types of uplinks ports.

Don't worry about your configuration. You will be able to use the same on the new switch.

Do not forget to create all VLANS you use on the new switch when you will copy old configuration to the new switch.

I am not sure what you mean by this. "Do not forget to create all VLANS you use on the new switch when you will copy old configuration to the new switch."

Is there something more that needs to be done than just copying the configuration?

[Mikhail.Galiulin]

Create VLANs.

Run "vlan X,Y,Z" command in configuration mode (X,Y,Z - numbers of your VLANs) to create VLANs in switchs VLAN database.

Then copy your config file to startup-config and reload the switch.

Matt,

The VLAN information is not displayed in the running configuration when the switch is set to VTP Server or Client, that's what Mikhail was implying.

If you have another switch as VTP server and the old switch as client, all you need to do is match the VTP domain on the new switch with the existing infrastructure, set it to VTP client and the VLANs will be copied automatically. If you don't have a VTP server or the old switch is the VTP server, you either have to change the status from server to transparent (this way the VLAN information will be visible in the running config) or manually type all the VLANs in global config mode on the new switch.

I believe I can offer a definitive answer if you tell us what kind of VTP infrastructure you are currently running. You can find this information by typing 'show vtp status' from each switch in your network.

Thanks for the explanation. Here is the output.

VTP Version : 2

Configuration Revision : 23

Maximum VLANs supported locally : 68

Number of existing VLANs : 28

VTP Operating Mode : Server

VTP Domain Name :

VTP Pruning Mode : Disabled

VTP V2 Mode : Disabled

VTP Traps Generation : Disabled

MD5 digest : 0x7E 0xF6 0x5B 0xF8 0x16 0x83 0xF0 0x2D

Configuration last modified by 10.10.30.2 at 3-24-93 01:49:00

The switch is acting like a VTP server with a NULL domain. What's the output from your remaining switches -or- this is the only switch in your network ?

[mmoore]

This is the only switch in our network with a configuration and on this network. It is connected to a router that is supposed to be part of the VLAN configuration.

[Edison Ortiz]

In that case, if you want to capture the entire configuration (including VLAN information), change the VTP mode from server to transparent.

This way you can copy and paste the entire configuration as is.

The command is

(config)#vtp mode transparent

After issuing that command, execute a 'show run' and you will see all Layer2 VLANs displayed along with the config.

I assume you are referring to the vtp command on the switch?

If so it is coming back as unrecognized.

[Edison Ortiz]

Ah, you are using a very old switch which still uses the old vlan method.

From the exec mode, type Vlan Database, then you can change the mode from there.

Well, as you can see the transparent command did not work again.

Still not recognizing the commands, I appreciate your help.

oh... But it does not work either (:
