Explanation/Reference:
Explanation:
channel-groupchannel-number[mode {on |active |passive}] Configures the port in a channel group and sets the mode. The channel-number range is
from 1 to 4096. The port channel associated with this channel group is automatically created if the port channel does not already exist. All static port
channel interfaces are set to mode on.
