Changing VSD Group Member States (NSM Procedure)

If necessary, for troubleshooting or maintenance, you can force a device to assume a new mode (master, backup, or ineligible) in a specified VSD group. To change a VSD group member state:

1. In the NSM navigation tree, select Device Manager > Devices, and then double-click the cluster to open the cluster configuration.
2. In the Device Manager, double-click the cluster to open the cluster configuration.
3. In the cluster navigation tree, select NSRP Directives > Exec Mode.
4. Select the device that will assume a new role, and then click Exec Mode. The Mode Selection dialog box appears.
5. Select the mode that the device is to assume:
   • Master—The VSD group member (primary device) that processes traffic sent to the VSI.
   • Backup—The VSD group member that becomes the primary device if the current primary device fails. The election process uses device priorities to determine which member to promote. When electing a new primary, an RTO peer has precedence over any other VSD group member, even if that member has a better priority rating.
   • Ineligible—The VSD group member that cannot participate in the election process. The preempt option must be enabled on the master device for this option to appear.
6. Click OK to save your changes.
