Symptom
When we create a portchannel and have configuration/ commands under it, then when we apply the portchannel config under the physical interface, the configuration under the portchannel do not get applied/copied automatically we have to add the configuration under the interface again.
C9500#sh run int po1
Building configuration...
Current configuration : 101 bytes
!
interface Port-channel1
switchport trunk allowed vlan 100,107,108,503
switchport mode trunk
end
C9500#sh run int te1/0/1
Building configuration...
Current configuration : 67 bytes
!
interface TenGigabitEthernet1/0/2
channel-group 1 mode active
end
Conditions
Creating a portchannel with configuration/ commands under it, then having apply the config to the interface again.
Observed this behavior on most Catalyst switches C3650, C3850, C4500, C6500, C9400 and C9500 as well.
Workaround
Manually copy the configuration from the portchannel to the interface as well
