To modify an existing 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-modify

name name-string

Specify the name of the VLAG.

Specify one or both of the following options:


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 2.2

Command introduced.

Version 2.4

Version 2.5

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 modifies an existing VLAG configuration.

Examples  This example shows how to modify a VLAG named spine1-vlag to lacp-timeout fast.

CLI network-admin@switch > vlag-modify name spine1-vlag lacp-timeout fast
