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 four 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.
