Configuring EtherChannel Load Balancing

This task is optional.
Purpose
Assigns all ports as static-access ports in the same VLAN, or
configures them as trunks.
If you configure the port as a static-access port, assign it to only
one VLAN. The range is 1 to 4096.
Assigns the port to a channel group, and specifies the PAgP or
the LACP mode.
For channel-group-number, the range is 1 to 10.
For mode, select one of these keywords:

auto—Enables PAgP only if a PAgP device is detected. It
places the port into a passive negotiating state, in which the
port responds to PAgP packets it receives but does not start
PAgP packet negotiation.

desirable—Unconditionally enables PAgP. It places the port
into an active negotiating state, in which the port starts
negotiations with other ports by sending PAgP packets.

on—Forces the port to channel without PAgP or LACP. In the
on mode, an EtherChannel exists only when a port group in
the on mode is connected to another port group in the on
mode.

non-silent—(Optional) If your switch is connected to a
partner that is PAgP-capable, configure the switch port for
nonsilent operation when the port is in the auto or desirable
mode. If you do not Specifies non-silent, silent is assumed.
The silent setting is for connections to file servers or packet
analyzers. This setting allows PAgP to operate, to attach the
port to a channel group, and to use the port for transmission.

active—Enables LACP only if a LACP device is detected. It
places the port into an active negotiating state in which the
port starts negotiations with other ports by sending LACP
packets.

passive—Enables LACP on the port and places it into a
passive negotiating state in which the port responds to
LACP packets that it receives, but does not start LACP
packet negotiation.
For information on compatible modes for the switch and its
partner, see PAgP Modes, page 1029
