I'm trying to config sub interfaces on a 2620xm ios 12.2, but it doesn't recongnize the 'encapuslation dot1q' command. I read that is has to be a fe link which it is, also, the ios should support dot1q, what am i missing here?

What IOS Feature Set (and version) do you have on that 2600XM? A show version command should tell you.
You need at least an IP Plus Feature Set to support 802.1q trunking:mike: Cisco Certifications -- Collect the Entire Set! -

What Mike was asking for was the full name of the IOS image, which you will find under the output from show version. For example:
System image file is "flash:c2600-i-mz.122-28.bin" -

sorry...c2600-i-mz.123-12.bin, c2600-i-mz.122-8.T5.bin
You just have IP Base feature sets -- so no 802.1q support.
The amount of Memory and the size of your FLASH (and your ability to get IOS images) may limit what IOS Feature Set/Versions you can run.
Check out the IOS Feature Navigator to get an idea of the Memory/Flash requirements for more advanced Feature Sets
