I Qoute: "Trunking is supported on all 8-MB switches running Cisco
IOS 12.0(5)XP and later. Trunking is not supported on some older
software releases and on some older Catalyst 2900 XL switches and
modules. For information about which older devices and software releases
support trunking, refer to the release notes for Release 11.2(8)SA6 or
earlier
(http://www.cisco.com/univercd/cc/td/doc/product/lan/c2900xl/index.htm)."

Now for what version of the 2900 you have I do not know. But it seems
the info on Ciscos site is kind of misleading in places. There is some
documentation that says it works and some say you have to have the add
on modules.
Your best bet if your not comfortable with the IOS command line is to
use the Web Interface or the Cisco Works Manager Interface. I say this
because I have really no way of knowing your experiance on this. I
wouln't do this on a live production switch.
If any one else could chime in and provide a 2900 configuration with
trunking setup would be nice. Just remove your IPs and replace with
x.x.x.x. I am interested in this also.
