-
10 Full—The LAG advertises a 10 Mbps speed and the mode is full
duplex.
-
100 Full—The LAG advertises a 100 Mbps speed and the mode is full

•
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
Administrative Advertisement field.
•
Neighbor Advertisement—Displays the neighbor LAG (the LAG to which
the selected interface is connected) that advertises its capabilities to the
LAG to start the negotiation process. The possible values are the same as
those listed in the Administrative Advertisement field.
•
Administrative Flow Control—Enable or disable Flow Control or enable the
auto-negotiation of Flow Control on the LAG.
•
Operational Flow Control—Displays the current Flow Control setting.
Click Apply. The switch is updated.
You can select another LAG for configuration by changing the LAG field.
Configuring LACP
A dynamic LAG is LACP-enabled; the Link Aggregation Control Protocol is run on
every candidate port defined in the LAG.
LACP system priority and LACP port priority 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.
An LACP channel group can have up to 16 Ethernet ports of the same type. Up to
eight ports can be active, and up to eight ports can be in standby mode. When
there are more than eight ports in an LACP channel-group, the switch on the
controlling end of the link uses port priorities to determine which ports are
bundled into the channel and which ports are put in hot-standby mode. Port
priorities on the other switch (the non-controlling end of the link) are ignored.
