Step 3 Configure the ports on Switch A to negotiate an EtherChannel bundle with the neighboring switch by
entering the set port channel command. This example assumes that the neighboring ports on Switch B
are in EtherChannel auto mode. The system logging messages provide information about the formation
of the EtherChannel bundle.
Switch_A> (enable) set port channel 2/3-6 desirable
Port(s) 2/3-6 channel mode set to desirable.

Step 4 After the EtherChannel bundle is negotiated, verify the configuration by entering the show port channel
command.
