Which IOS version to configure ethernet sub-interfaces on a 2611/2621 router?

Marco Bailey

Hi, i'm attempting to set up trunking 801Q on a 2621 router with software version 11.3 (2) XA4. Looks like this IOS does not support trunking according to the Cisco feature tool. How do I/or where can i download a newer IOS for my router to enable trunking it it's sub interfaces?

I'm not sure that you can with a 2621 Router as you need L2 functionality. I have a 821 which has a built in 4 port Switch. It's running v12.4 and has 802.1Q support, I also have a 2620 which has just the one e/net port, running v12.2, which does not.

If they are 10MB interface cisco there is one IOS version that will work. I think it was made for labs only. c2600-ik9s-mz.122-46.bin

Seems that 12.2(XT) might work for your router
