• All ports in the LAG have the same back pressure and flow control modes.
• All ports in the LAG have the same priority.
• All ports in the LAG have the same transceiver type.
• The device supports up to 32 LAGs, and eight ports in each LAG.
• Ports can be configured as LACP ports only if the ports are not part of a
previously configured LAG.
Ports added to a LAG lose their individual port configuration. When ports are
removed from the LAG, the original port configuration is applied to the ports.
The device uses a hash function to assign packets to a LAG member. The
hash function statistically load-balances the aggregated link members. The
device considers an Aggregated Link to be a single logical port.
Aggregate ports can be linked into link-aggregation port-groups. Each group
comprises ports with the same speed, set to full-duplex operations.
Ports in a LAG can contain different media types if the ports are operating at
the same speed. Aggregated links can be manually or automatically
configured by enabling LACP on the relevant links.
LACP Parameters
To define LACP LAGs, configure LACP global and port parameters, such as
LACP system priority, timeout, and port priority.
With all factors equal, when the LAG is configured with more candidate ports
than the maximum number of active ports allowed, the switch activates the
highest priority candidate ports from the dynamic LAG.
To set LACP parameters:
1 Click Switching > Link Aggregation > LACP Parameters in the tree
view to display the LACP Parameters page.
The LACP parameters for all ports are displayed.
2 Enter the global LACP System Priority (1-65535) value that determines
which candidate ports will become members of the LAG.
The page displays the LACP settings of the ports on the selected unit.
