I'm trying to setup port trunking between a 3com 2924-SFP and a HP Procurve 2910al switch and running into problems. The trunk appears to be active (lights on the ports blinking) but there is no traffic flowing, can't see anything sitting behind either switch.
By default the 3com had STP enabled so I enabled it on only the trunked hp ports - that didn't work. I removed STP from both switches, that didn't work either... tried various combinations of things and nothing has worked. LACP is disabled.
I do have a couple VLAN's setup on the HP and ip routing is enabled. Don't know if I have to have a matching VLAN on the 3com side (even though the entire 3com is in 1 subnet).
Thanks in advance for the help!
