Greetings-

I have a 2621 router running IOS version 12.3(13) and I am trying to set up
802.1q VLAN on a sub interface. Well when i go down to the sub interface
and type the following command.. "encapsulation dot1q 1 native"; I get an
error. I hit the ? for all the commands available and the encapsulation is
not available. I have confirmed I was down in the subinterface. I check
another 261 that I have in production running ios version 12.2(16a) and it
does have the encapsulation command. Now the firts router is running some
nat transalations, but that shouldn't have anything to do with it, right?

Any ideas?

Frank

IIRC, you have to be running an IP+ image for VLAN trunking.

Doug-

You do man, I loaded the Enterprise IP Plus after looking at my other
router. Appreciate the quick response.
