Specifying the EtherChannel Protocol
Note The default protocol is PAgP.
Note You can specify only one protocol, PAgP or LACP, per module.
To specify the EtherChannel protocol, perform this task in privileged mode:
This example shows how to specify LACP for modules 2 and 3:
Console> (enable) set channelprotocol lacp 2,3
Mod 2 is set to LACP protocol.
Mod 3 is set to LACP protocol.
Console> (enable)
Use the show channelprotocol command to display the protocols for all modules.
Task Command
Specify the EtherChannel protocol. set channelprotocol [pagp | lacp] mod
