channel-group channel-group-number mode {auto [non-silent] | desirable [non-silent] | on |
active | passive}
no channel-group
Specify the channel group number. The range is 1 to 64.
Specify the EtherChannel Port Aggregation Protocol (PAgP) mode of
the interface.
Unconditionally enable Link Aggregration Control Protocol (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 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 an interface into an active negotiating state, in
which the interface starts 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.
Force the interface to channel without PAgP or LACP.
With the on mode, a usable EtherChannel exists only when an interface
group in the on mode is connected to another interface group in the on
mode.
Enable LACP only if a LACP device is detected.
Passive mode places an interface into a negotiating state in which the
interface 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. When passive is enabled, silent operation is the
default.
