channel-group channel-group-number mode on
Specify the channel group number. The range is 1 to 6.
Specify the EtherChannel mode.
Unconditionally enable Link Aggregation Control 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.
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.
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. An
EtherChannel is formed with another port group that is in the desirable or
auto mode. When desirable is enabled, silent operation is the default.
(Optional) Use in PAgP mode with the auto or desirable keyword when
traffic is expected from the other device.
Enable on mode.
In on mode, a usable EtherChannel exists only when both connected port
groups are in the on mode.
Enable LACP only if a LACP device is detected.
Passive mode places a port into a negotiating state in which the port
responds to received LACP packets but does not initiate LACP packet
negotiation. A channel is formed only with another port group in active
mode.
