My Cisco 851W does not support Dot1Q !!

nkila_lna · ‎09-15-2007

Hi Friends

My Cisco 851W does not support Dot1Q on its Fastethernet interfaces :

I mean these commands are not accepted by Cisco 851W :

interface fa0.1

encapsulation Dot1Q

I need this in order to route between my Vlan (Wifi and non WIFI Vlan) as indicated in the Cisco official guide document

so what is wrong ?

Regards

please help me urgent

Do you have an IP address on the fa0 port?

If you are going to use dot1q, the primary / physical interface doesn't get an address, only the subinterfaces.

Posting your (sanitized) config would be a great help ....

Thanks

Scott
