CHANNEL GROUP

channel-group

Overview Use this command to either create a new dynamic channel group while at the
same time adding a port to it, or to add a port to an existing dynamic channel
group. Note that you must also set the LACP mode to be either active or passive.
You can create up to 32 dynamic (LACP) channel groups (and up to 96 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.

Mode Interface Configuration
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.

Command Reference for FS980M Series
AlliedWare Plus™ Operating System - Version 5.4.7-0.x
Description
<1-32> Specify a dynamic channel group number for an
LACP link. You can create up to 32 dynamic (LACP) channel
groups (in addition to up to 96 static channel groups).
Enables initiation of LACP negotiation on a port. The port
will transmit LACP dialogue messages whether or not it
receives them from the partner device.
Disables initiation of LACP negotiation on a port. The port
will only transmit LACP dialogue messages if the partner
device is transmitting them, i.e., the partner is in the active
mode.
