Port Channel and VLAN trunking

When configuring trunking of VLANS accross a Port Channel, do we need to configure vlan pruning on both the port-Channel port and the physical ports ???

E.g. do I need to apply the "switchport trunk allowed vlan add " command under each physical port and the port channel port ? Or only under the port channel port ?

Thanks

In short, yes. Configure the port channel interface exactly as you do the physical interfaces and both ends should be an exact match. otherwise you will have problems getting the channel to come up or stay up.

Ok. thanks but do I need to configure ONLY the port-channel port...or do I also need configuring the physical port ?

You will also need to configure the physical ports.
