Hi
We have a CME router Cisco 2951. We bought another one to act as backup. I've copied most of the config from Primary CME to Backup CME. For some reason I can't create interface VLAN(SVI) on the Backup CME. They have similar iOS and hardware (except ISM module) so not sure what is the diference.

I read that to use switch commands I would need etherswitch module but I don't have it in the Primary CME.
Kind Regards
Michael
Solved! Go to Solution.

Yes that's a pure layer 3 router no layer 2 at all in place or else you would have a vlan output even if nothings configured
disregard that vlan 1 statement its not doing anything and it shouldn't be there , there is no requirement form looking at the config to even try replicate that , im still confused how its even there on primary as it layer 3 router maybe something to do with the ISM but I can confirm its not doing anything and does not require to be on the new backup router

SVIs are can be created when the device has Layer 2 ports that can be configured to be part of the same VLAN as the SVI. The Cisco 2951 only have Layer 3 ports unless a Switch module is installed.
Could you please add a full 'show run' of your Primary CME Router?

08-23-2016 06:28 AM
hmmm there's no intervlan routing on that config and no vlans in use at all from what I see its pure layer 3 router no switching in place
and I agree with Hector you need a switching module to do SVIs on router as I have quite a view variations of them throughout our network

Hi Mark
On the primary CME there is
interface Vlan1
description $ES_LAN$
no ip address
I can't create one on secondary although it have almost the same iOS and hardware so am I missing something?
08-23-2016 06:37 AM
Hi
That's not in use no ip address on it , if svi has no ip address its no doing anything at L3
im still trying to figure how that's on a 2951 without an SM as I cant do it on any of mine that are pure L3
Do you have the syntax for this command ----show vlan ?
That will really tell confirm if its l2 at all as examole from one of my 2951s without an SM

It was puzzling for me and I wasn't sure if it's needed but had some issues when connecting backup CME.
Now I rebuild it and it's working fine.
Thank you for your support.
