Hi Carlo,
" Bridged interfaces: vlan 1(D), pkey 0x7fff" means that there is no active ports that are members of vlan1.
This is because vlan 1 is not on port-channel 2:
interface port-channel 2 switchport trunk allowed-vlan none
interface port-channel 2 switchport trunk allowed-vlan 236
Can you add it to the port-channel?
interface port-channel 2 switchport trunk allowed-vlan 1
As for adding pkey 0x236 to the sm, which Subnet manager are you using? Host based? Switch based (somewhere else)? UFM?
