channel-group
Overview
Use this command to add the device port to a dynamic channel group specified by
the dynamic channel group number, and set its mode. This command enables
LACP link aggregation on the device port, so that it may be selected for
aggregation by the local system. Dynamic channel groups are also known as LACP
channel groups, LACP aggregators or etherchannels.
You can create up to 2 dynamic (LACP) channel groups (or up to 2 static channel
groups).
Use the
no
variant of this command to turn off link aggregation on the device port.
You will be returned to Global Configuration mode from Interface Configuration
mode.

Usage
All the device 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 device 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 device port, and
can be referred to in most other commands that apply to device 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, ‘
po2
’ refers to
the LACP channel group with channel group number
2
.
Link aggregation hashes the source and destination MAC address to select a link
on which to send a packet. So packet flow between a pair of hosts always takes the
same link inside the Link Aggregation Group (LAG). The net effect is that the
bandwidth for a given packet stream is restricted to the speed of one link in the
LAG. This hashing mechanism cannot be changed.
Parameter
Description
<
dynamic-channel-
group-number
>
<1-2>
Specify a dynamic channel group number for an
LACP link.
active
Enables initiation of LACP negotiation on a port. The port
will transmit LACP dialogue messages whether or not it
receives them from the partner system.
passive
Disables initiation of LACP negotiation on a port. The port
will only transmit LACP dialogue messages if the partner
systems is transmitting them, i.e., the partner is in the active
mode.
