I keep getting the error "Selected ports belong to devices that cannot support Dynamic and Trunk modes." It's a 2924xl, I need to be able to trunk to a 3com switch. I have removed all multi-vlans, but it still gives that error. The goal is to create say, 3 vlans, and 2 trunk ports. Hopefully I can do this. Any help appreciated.

Seems to me that the switch you are trying to connect to from the Cisco switch does not support the trunk encapsulation. Try using dot 1 q as your encapsulation instead of ISL. You can only trunk to a switch that supports your trunk encapsulation, Cisco supports two types by default: 1# ISL (it's own proprietary standard) and
2# 802.1q (IEEE standard, if my memory serves me)
This should help solve your problem.
