Unmoving encapsulation error

My router that's connected to my switch won't "take" the encapsulation command. I'm stuck in trying to set up my network until I can get past it. Here's what I put:

router(config)#int fa 0/0
router(config-if)#no shut
router(config-if)#int fa 0/0.1
router(config-subif)#encapsulation dot1q 1

At this point I got the error % Unrecognized command with the "^" symbol underneath the "e" in encapsulation. I tried all kinds of permutations with no success. I even put just a "?" at the (config-subif)# to see what my options were, but nothing showed for "encapsulation." My IOS is 12.2 and my router is a 2600 - a lab router.

Any help?

I was checking Cisco Feature Navigator and you'll need minimum 12.2T to do IEEE 802.1Q VLAN Trunking, here is the web side if you want to check it yourself.

According to table 2, his router should support 1Q..assuming he has one of the models listed in the table. I think the newest release I saw on there was a 2620, requiring 12.1(3a)T. I may be wrong but I just glanced at that...

I'm running several 2610 with 12.3 and they support 802.1Q, in this case he is running 12.2 and for the cisco web side he need at least 12.2T to do it.

Tricon7, can you please put here what IOS are you running?.

Hope this help.

I would add that it needs to be an IP Plus feature set, with the letters "is" in it or better, "js", "jk", will also work.

Here is the output from the "show version" command on that router. However, my professor who's a CCNP says that the router should be supporting dot1q encapsulation; he's not aware of any IOS in our lab which would prevent it.

your IOS is a standart IP image denoted by the "i" in the name, you need atleast the enhanced feature set "IS" somthing like this:

c2600-is-mz.123-34.bin

Hi Tricon7;

Yeah, you'll need to upgrade your IOS. Also did you cut the sh ver output?, i don't see any memory flash in the output.

Hope this help.
