If a member port's config is not synced it is unbundled from the bundle, and may be put in errdisable state.

Hi,
I just thought about how to add an interface to a running channel and I am
wondering about the config after adding a port.
If you have an existing channel and use "channel-group ..." on a clean
interface to add it the config of the physical interface is not extendet
with the config of the channel (for example the "switchport trunk allowed
vlan ..." line).
But If you change the config of the channel the config of the member ports
is updated automatically.
What happens if a have 2 ports in the channel with different allowed vlans ?
Is the physical interface config ignored (and the channel interface vlans
are valid on all members) or does this really work and a vlan only
configured on one port of the channel is handled like a vlan on a
non-channel port ?
kind regards
Rolf
