configuring NM-16ESW-1GIG Module

I installed the above module on cisco 3745 router but when trying to config IP address for one of its interfaces I got the following error :

"IP addresses may not be configured on L2 links"

I tried to use no switchport but doesnt successfull.????


Re: configuring NM-16ESW-1GIG Module


AFAIK you wont be able to configure any ip address on the L2 ports , the ports are very much like any other normal L2 switch ports and you wont be able to configure individual ip address to them. Instead you can confiugre SVI(Switched Virtual Interface) vlan interfaces with ip address and make the ports as a member of those vlans.

Re: configuring NM-16ESW-1GIG Module

Did you create the layer 2 vlan in the vlan database ? At the prompt type vlan database and enter vlan 2 then exit .
