Freddy,
VTP is Cisco propiertary and the 3Com will not
understand it. It might come up but it won't learn the
VLANs. 3Com does standard 802.1q which is one spanning
tree instance. I'm not sure offhand if they have their
own method of doing spanning tree per VLAN like Cisco
and others do.
If you focus on one spanning tree instance for that
link, VTP transparent mode, and use 802.1q then it
should come up and be fine.
Doing 'set port 1/1 nonegotiate' on the cisco side
configures the cisco not to try to negotiate either
the trunk or port channel features which would also be
propiertary to cisco.
