... and an independent port acts like it's not an etherchannel member by
the way. Forgot that part. So if you have a L2 etherchannel running STP
it would normally look like this:
interface GigabitEthernet1/1
switchport
switchport access vlan 2
switchport mode access
channel-group 1 mode active
!
interface GigabitEthernet1/2
switchport
switchport access vlan 2
switchport mode access
channel-group 1 mode active
!
interface Port-channel1
switchport
switchport access vlan 2
switchport mode access
!
With both ports "up" and LACP active ("P"):
Switch# show spanning-tree vlan 2
...
Po1 Desg FWD 20000 128.1665 P2p
And if both ports were independent:
Switch# show spanning-tree vlan 2
...
Gi1/1 Desg FWD 10000 128.1665 P2p
Gi1/2 Desg FWD 10000 128.1665 P2p
