Hello,

When is the command "channel-protocol" used when configuring etherchannel? From the doc CD 12.1(19)EA1:

"Use the channel-protocol interface configuration command to configure an EtherChannel for the Port Aggregation Protocol (PAgP) or Link Aggregation Control Protocol (LACP). Use the no form of this command to disable PAgP or LACP on the EtherChannel.

channel-protocol {lacp | pagp}
no channel-protocol
Syntax Description

lacp
 Configure an EtherChannel with the LACP protocol.
 
pagp
 Configure an EtherChannel with the PAgP protocol.
 
Defaults
No protocol is assigned to the EtherChannel."

The default is no protocol which seems to say we need this cmd whether we are using PagP or LACP. However, I remembered that I never need to configure this command to get the etherchannel to work. All I need to config is "channel-group mode". Hope someone can clarify. Thank you.

Rgds
David
