Adding vlan to lag

    Hello we have 8400s and I need to add a vlan to an existing lag that already has vlans. When I add the new vlan do I need to list all the current vlans to the allowed vlans command or can I just put the one I need to add and it will append to the list ?

    Hi Joseph,

    You can just add a new vlan to the allow list without add the current one again.

    interface lag 10
    no routing vlan
    trunk native 10
    vlan trunk allowed 10,20,30,40

    For example when add vlan 50 you can just configure it as:
    vlan trunk allowed allowed 50

    This will end up in....
    vlan trunk allowed 10,20,30,40,50
