W Commands
This chapter describes the Cisco NX-OS unicast routing commands that begin with the letter W.
weight
To set the default weight for routes from this neighbor, use the weight command. To restore the default values, use the no form of this command.

weighting
To specify the initial weighting value of the Gateway Load Balancing Protocol (GLBP) gateway, use the weighting command. To restore the default values, use the no form of this command.
weighting maximum [ lower lower ] [ upper upper ]
no weighting maximum [ lower lower ] [ upper upper ]
Syntax Description
Defaults
The default gateway weighting value is 100 and the default lower weighting value is 1.

Usage Guidelines
The weighting value of a virtual gateway is a measure of the forwarding capacity of the gateway. If a tracked interface on the router fails, the weighting value of the router may fall from the maximum value to below the lower threshold, causing the gateway to give up its role as a virtual forwarder. When the weighting value of the gateway rises above the upper threshold, the gateway can resume its active virtual forwarder role.
Use the glbp weighting track and track commands to track an interface. If the interface goes down, GLBP reduces the weighting for the gateway by the specified value.
Examples
This example shows how to set the weighting of the gateway for GLBP group 10:

weighting track
To specify a tracking object where the Gateway Load Balancing Protocol (GLBP) weighting changes based on the availability of the object being tracked, use the weighting track command. To remove the tracking, use the no form of this command.
weighting track object-number [ decrement value ]
no weighting track object-number [ decrement value ]

Usage Guidelines
The weighting track command ties the weighting of the GLBP gateway to the availability of its interfaces. This command is useful for tracking interfaces that are not configured for GLBP; for instance, you can track the interface that connects the gateway to the IP network.
When a tracked interface goes down, the GLBP gateway weighting decreases by the configured decrement value. For each GLBP group, you can track a separate list of interfaces.
When the tracked interface comes back up, GLBP increments the weighting by the same amount.
When multiple tracked interfaces are down, the configured weighting decrements are cumulative.
Use the track command to configure each interface that you want to track.
Examples
This example shows that Ethernet interface 1/1 tracks two interfaces represented by the numbers 1 and 2. If interface 1 goes down, the GLBP gateway weighting decreases by the default value of 10. If interface 2 goes down, the GLBP gateway weighting decreases by 5.
