# VSD Group List

A Virtual Security Device (VSD) group is a set of physical devices that collectively comprise a single VSD. One physical device acts as the master of the VSD group. The virtual security interface (VSI) of the VSD is bound to the physical interface of the master. Other physical devices in the VSD group act as backups.

For more information on VSD groups, refer to the Concepts & Examples ScreenOS Reference Guide available on the documentation CD that shipped with your device and also on the Juniper Networks documentation site.

## VSD Group List

This table lists existing VSD groups and the following information for each:

Group ID: The number in this field identifies the VSD group.

Priority: Indicates the priority number of the local device. A priority number closer to 1 has higher priority.

Preempt: Indicates whether or not the device is using the preempt option.

Hold-Down Time: Indicates the amount of time set to delay a failover.

Mode: Indicates which mode the system is in. The system can be in one of six modes (or states):

Master The state of a VSD group member that processes traffic sent to a VSI for that group.

Primary Backup The state of a VSD group member that becomes the master should the current master step down. The election process uses device priorities to determine which member to promote. Note that when electing a new master, an RTO peer has precedence over any other VSD group member, even if that other member has a better priority rating.

Backup The state of a VSD group member that monitors the status of the primary backup and elects one of the backup devices to primary backup if the current one steps down.

Initial The transient state of a VSD group member while it joins a VSD group, either when the device boots up or when it is added via the set nsrpvsd-group id <id_num> command.

Ineligible The state that an administrator purposefully assigns to a VSD group member so that it cannot participate in the election process.

Inoperable The state of a VSD group member after a system check determines that the device has an internal problem (such as no processing boards) or a network connection problem (such as when an interface link fails).

Master: Indicates the ID number of the device that assumes the role of master for a VSD group.

Primary Backup: Indicates the ID number of the device that assumes the role of Primary Backup.

Group Members: Indicates the ID number of other devices in the VSD group. (If there are only two members, one acting as the master and the other as the primary backup, then this field is empty.)

Configure: Click Edit to modify the VSD group, or Remove to delete the group.
