Usage Guidelines

Usage Scenario

After a PW protection group is configured, you can run the display vsi protect-group command to view summary or detailed information about the PW protection group of a specified VSI and check whether PW configurations have taken effect. When maintaining a PW protection group, you can track the running status of the group by viewing historical switchover information about PWs in the group.

Prerequisites

A PW protection group has been created and the primary and secondary PWs have jointed the group.

**Table 2** Description of the **display vsi protect-group** command output
Item	Description
Protect mode	PW redundancy mode of a PW protection group: PW redundancy master: The PW redundancy mode is master/slave.
Reroute policy	Revertive switching policy of a PW protection group. The default revertive switching delay is 30s. In master/slave mode, you can modify the revertive switching policy by running the reroute command in the protect-group view.
Last change time	Last PW switching time.
Last change action	Last PW switching action. A PW is uniquely identified by peerIP:VcID.
Last change reason	Reason for last PW switching: manual force switch: The PW switching is triggered by the protect-switch force command. manual clear switch: The PW switching is triggered by the protect-switch clear command. config changed: The PW switching is triggered by configuration changes such as PW addition, PW deletion, or PW priority changes. fault detected: The PW switching is triggered by failures detected by BFD or VCCV. PW down: The PW switching occurs because the active PW goes Down. PW up: The PW switching occurs because the active PW goes Up again.
Holdoff remain time	Remaining time before a switching is performed. NOTE: If the value is --, no switching delay is configured.
Reroute remain time	Remaining time before a revertive switching is performed. NOTE: If the value is --, no revertive switching delay is configured.
Members	Displays members in a PW protection group.
Pri/Sec	Primary/secondary status of a PW: Primary: The PW is a primary PW. Secondary: The PW is a secondary PW.
