AGGREGATING PORTS
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.
