This section contains information for configuring Link Aggregation,
which optimizes port usage by linking a group of ports together to form a
single LAG. A Link Aggregation Group (LAG) aggregates ports or VLANs
into a single virtual port or VLAN

.

Aggregating ports multiplies the

bandwidth between the devices, increases port flexibility, and provides
link redundancy. Ensure the following:

■

All ports within a LAG must be the same media type.

■

All ports added to an existing LAG which are part of a tagged VLAN
inherit the existing VLAN tags.

■

Auto-negotiation mode is not configured on the port.

■

The port is in full-duplex mode.

■

All ports in the LAG have the same ingress filtering and tagged modes.

■

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 eight LAGs, and eight ports in each 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.
