Syntax Description channel-group-number Specify the channel group number. The range is 1 to 12.
mode Specify the EtherChannel mode of the port.
active Unconditionally enable Link Aggregation Protocol (LACP).
Active mode places a port into a negotiating state in which the port initiates
negotiations with other ports by sending LACP packets. A channel is
formed with another port group in either the active or passive mode.
auto Enable the Port Aggregation Protocol (PAgP) only if a PAgP device is
detected.
Auto mode places a port into a passive negotiating state in which the port
responds to PAgP packets it receives but does not start PAgP packet
negotiation. A channel is formed only with another port group in desirable
mode. When auto is enabled, silent operation is the default.
desirable Unconditionally enable PAgP.
Desirable mode places a port into an active negotiating state in which the
port starts negotiations with other ports by sending PAgP packets. A
channel is formed with another port group in either the desirable or auto
mode. When desirable is enabled, silent operation is the default.
non-silent (Optional) Used with the auto or desirable keyword when traffic is
expected from the other device.
on Enable on mode.
In on mode, a usable EtherChannel exists only when both connected port
groups are in the on mode.
passive Enable LACP only if a LACP device is detected.
Passive mode places a port into a negotiating state in which the port
responds to LACP packets it receives but does not initiate LACP packet
negotiation. A channel is formed only with another port group in active
mode.
