Use the following procedure to display and graph VRRP interface statistical information.

## Prerequisites

- Install the Advanced License.

- Enable IP routing globally on the switch.

- Assign an IP address to the VLAN that you want to enable with VRRP.

  Routing is automatically enabled on the VLAN when you assign an IP address to it.

## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click VRRP.

3. In the work area, click the Interfaces tab.

4. In the table, select the desired interface.

5. In the toolbar, click Graph.

6. Using the provided fields, view and graph the VRRP statistical information.
