Port-channel and Member's Config Precedence?

[Matthew Martin]

Hello All,

Switch: WS-C2960X-24PS-L

IOS: 15.2(2)E5

I configured this switch with one Port-channel (*Po1) and it has Gi1/0/23 and Gi1/0/24 as its members.

Both Gi ports are configured with switchport mode trunk, and so is the Port-channel.

I was wondering who's configuration takes precedence, the "Port-channel" or the "GigabitEthernet" members of the Port-channel? I wanted to add the "switchport trunk allowed vlan ..." command, but I wasn't sure if I need to add it to all 3 of the "Interface" configs, or if it only needs to be added to the Port-channel configuration?

Thanks in Advance,

Matt

 Hi  @Matthew Martin

Port channel has the precedence so you must add to the port channel. Dont forget the "add" command to avoid downtime.
