Reconfiguring a set of teamed NICs

[notoftheearth]

Suppose I have a set of 5 ports on a switch which are all teamed and allow traffic on vLAN5 I want to allow traffic on vLAN6 on the group of teamed ports.  Can this change be made without any downtime?  In other words, can the change be made in such a way that vLAN5 traffic can always pass through at least one of the ports without any dropped frames while I'm doing the reconfig?

Thanks

When you say "teamed" I take it you are talking about an etherchannel?

Well you should have an etherchannel interface like interface po1 (port-channel 1) for example.

Just make any changes you require to the port-channel interface and NOT the inidividual interface that make up the port-channel group.

If you make a change to the and individual interface you  WILL bring down the etherchannel and you WILL have downtime.

To add vlan 6 to the etherchannel you just need to enter the interface po and add the vlan with:

#switchport trunk allowed vlan add 6
