14.2.2 Checking GSRP Status
When you configure GSRP on the Switch, you can check the GSRP state at the following points.
- <Structure of this section>
(1) Confirmation after configuration setting
Use the show gsrp command to check the GSRP configuration. You can check whether the GSRP configuration set with configuration commands is correct. You can also check whether the priority of the master and backup selection conditions (Selection Pattern), the Layer 3 redundancy switching settings, the VLAN group IDs, and the VLANs that belong to VLAN groups are the same on both Switches in a GSRP group. If Layer 3 redundancy switching is configured, you can check whether the IP addresses assigned to the VLANs belonging to VLAN groups are the same on both GSRP switches. For details on checking IP address, see ConfigurationGuide: Checking Vol.1" "24.11.2 VLAN status, ConfigurationGuide: Checking up/down of Vol.3" "2.2.2 IPv4 Interfaces, or ConfigurationGuide: Checking up/down of Vol.3" "19.2.2 IPv6 Interfaces. Note that, in the backup state, the interfaces are down for the VLANs that belong to VLAN groups.
The following figures show example results of executing the show gsrp detail command and the show gsrp vlan-group command.

(2) Confirmation during operation
A pair of Switches forms a GSRP group.You can check whether either switch is the master for a VLAN group.You can also check whether each VLAN group has only one master. By using the show gsrp command, you can check with which VLAN group each of the paired Switches is associated.
