•
Operational Advertisement—Displays the administrative advertisement
status. The LAG advertises its capabilities to its neighbor LAG to start the
negotiation process. The possible values are those specified in the Auto
Advertisement Speed field.
•
Back Pressure—Check Enable to enable the Back Pressure mode on the
LAG (used with Half Duplex mode) to slow down the packet reception speed
when the switch is congested.

Configuring LACP
A dynamic LAG is LACP-enabled, and LACP runs on every candidate port defined
in the LAG.
LACP Priotity and Rules
LACP Priotity and Rules
LACP system priority and LACP port priority are both used to determine which of
the candidate ports become active member ports in a dynamic LAG configured
with more than eight candidate ports.
The selected candidate ports of the LAG are all connected to the same remote
device. Both the local and remote switches have a LACP system priority.
The following algorithm is used to determine whether LACP port priorities are
taken from the local or remote device: the local LACP System Priority is compared
to the remote LACP System Priority. The device with the lowest priority controls
candidate port selection to the LAG. If both priorities are the same, the local and
remote MAC addresses are compared. The priority of the device with the lowest
MAC address controls candidate port selection to the LAG.
