Thanks for feedback! HMMM.... Why does the PG not have this in their solutions?
In this lab they are not doing etherchannels on fa 0/19-24 like they usually do. Instead they specifically ask to only "configure layer2 gigabitethernet0/1 on both catalyst switches." So I guess the config would be just as you stated except you wouldn't configure Gi0/2.? I always thought you needed more that one interface to join the ether-channel. And don't you have to specify a number after channel-group? interface GigabitEthernet0/1 switchport trunk encap dot1q switchport mode trunk channel-group mode active --- Ralph Olsen <[EMAIL PROTECTED]> wrote: > I believe the PAGP is in reference to the > Etherchannel.
