Virtual Link Aggregation (VLAG)


To create a new virtual link aggregation group (VLAG), use this command.


Informational Note:  Before you configure VLAGs, you must have two switches in a cluster configuration. One switch is the local switch used to specify the local port and the other is a peer switch used to specify the peer port.

A switch can only participate in one cluster. 

Syntax   vlag-create name

name name-string

Specify the name of the VLAG.

port vlag-usable-port

Specify the local VLAG port.

peer-port vlag-usable-port

Specify the peer VLAG port.

mode active-standby|

Specify the mode for the VLAG. Active-standby indicates one side is active and the other is in standby mode. (Not Supported) Active-Active indicates that both sides of the VLAG are up by default.

peer-switch fabric-node-name 

Specify the fabric name of the peer switch.

peer-port port-number

Specify the port number on the peer switch.


Specify the failover action as move or ignore.

lacp-mode off|passive|active

Specify the LACP mode.

lacp-timeout slow|fast

Specify the LACP timeout as slow (30 seconds) or fast (4 seconds).

lacp-fallback bundle|individual

Specify the LACP fallback mode as bundle or individual.

lacp-fallback-timeout seconds

Specify the LACP fallback timeout between 30 and 60 seconds. The default value is 50 seconds.

lacp-port-priority number

Specify the LACP port priority as a value between 1 and 65535.

Defaults   None.

Access   CLI


Version 1.2

Command introduced.

Version 2.1

The parameters for failover and LACP added.

Version 2.2

The parameters for mode lacp-mode, active-standby and active-active added. Local-port changed to port.

Version 2.2.6

The parameter, port, deprecated. The parameters, port vlag-usable-port name, and peer-port vlag-usable-port name added.

Version 2.4.0

The parameters, lacp-fallback and lacp-fallback-timeout, added.

Version 2.5.0

The parameter, lacp-port-priority, added.

Usage   A virtual link aggregation group (VLAG) allows links that are physically connected to two different Pluribus Networks devices to appear as a single trunk to a third device. The third device can be a switch, server, or any Ethernet device. A VLAG can provide Layer 2 multipathing, which allows you to create redundancy by increasing bandwidth, enabling multiple parallel paths between nodes and loadbalancing traffic where alternative paths exist. This command creates a new VLAG.

Examples  This example shows how to create a VLAG with identifier 1 to aggregate the links connected to port 1 of both the local and peer switch.

CLI network-admin@switch > vlag-create id 1 port 1 peer-switch a1634:b peer-port 1
