Hi All,

I have cisco 1801 router with 8 ports.

I am trying to setup two different vlans on this equipment. fa 1 is connected to my LAN and Fa 2 is connected to my WAN.

I want to have a vlan 1 used by Fa 0 and vlan 2 used by fa 2. Can you please check my config and let me know of any configuration problem?

Hello Tauseef,

by default all "switch" ports are in vlan1.

so under each interface that should be in vlan2 you should place

int fas X

switchport mode access

switchport access vlan 2

an example of config for 1801 is here

http://www.cisco.com/en/US/docs/routers/access/1800/1801/software/configuration/guide/sampconf.html

Hope to help

Giuseppe
