I have configured my port-channels on my cat as follows:
Switchport
Switchport trunk encapsulation dot1q
switchport mode trunk
There are 3 gig ports connecting my HP Procurve switch. My HP will automaticly put them in a trunk group.
My problem is when I do this the cat and the HP quit passing vlan information. The default vlan 1 works fine but the other vlan's no longer work.
Funny thing is, they will pass vlan's if I only use 1gig port and have it set like the following:
Interface GigabitEhternet3/45
switchport trunk encapsulation dot1q
switchport mode trunk
and I have the connected port on the HP set as TAGGED in all the vlan's.
Anything I'm doing wrong? or do I need to go to HP with the problem on their side.
Thanks.
