channel-group mode (LACP)
Use this command to add the switch port to a dynamic (LACP) channel group specified by the
channel group number, and set its mode. You can create up to 31 channel groups. This
command enables LACP link aggregation on the switch port, so that it may be selected for
aggregation by the local system. LACP channel groups are also known as LACP aggregators,
dynamic channel groups, or ether channels.
Use the
no channel-group
command to turn off link aggregation on the switch port.
Syntax
channel-group <1-65535> mode {active|passive}
no channel-group
Mode
Interface mode
Usage
All the switch ports in a channel-group must belong to the same VLANs, have the same tagging
status, and can only be operated on as a group. All switch ports within a channel group must
have the same port speed and be in full duplex mode.
Once the LACP channel group has been created, it is treated as a switch port, and can be
referred to in most other commands that apply to switch ports.
To refer to an LACP channel group in other LACP commands, use the channel group number.
To specify an LACP channel group (LACP aggregator) in other commands, prefix the channel
group number with
po
. For example, ‘po4’ refers to the static channel group with channel
group number
4
.
