SM-ES2-24 Enhanced Etherswitch L2 Service Module

[briand07032]

Hi

If I install an Enhanced Etherswitch Layer 2 Service Module (SM-ES2-24) in a 2911 router can I do the following:-

- create SVIs on the router ie vlan interfaces

- create the relevant vlans on the Etherswitch and assign to access ports

- have the router perform the layer 3 functions for the vlans

and will this work through the service module slot connection/backplane?

I just can't find any documentation that says this.

Cheers

Brian.

Hi Brian,

Cisco ether switch module is having same feature set of cisco 3560 switches and link shared by Arjun also gives how to configure the same.So yes you can have those lan creation feature with etherswitch and SVI creation.

Hope it Helps..

Hi, I have installed 1 x SM-ES2-24 in  Cisco 2911.  This module will act as a Trunk port with another L3 switch to carry VLAN 999,514,515,516.  Kindly advice whether our configuration is correct or not because I'm quite confused with the relation of port gi 1/0 and gi 1/1 with sm-es2-24.
