Specify the EtherChannel Port Aggregation Protocol (PAgP) or Link
Aggregration Control Protocol (LACP). mode of the interface.
Unconditionally enable LACP.
Active mode places an interface into a negotiating state in which the
interface initiates negotiations with other interfaces by sending LACP
packets. A channel is formed with another port group in either the active
or passive mode. When active is enabled, silent operation is the default.
Enable PAgP only if a PAgP device is detected.
Auto mode places an interface into a passive negotiating state, in which the
interface responds to PAgP packets it receives but does not initiate 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 an interface into a negotiating state in which the
interface initiates negotiations with other interfaces 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.
(Optional) Used with the auto or desirable keyword when PAgP traffic is
expected from the other device.
