How to configure the timeout interval for VRRP packets

In a VRRP group, if the backup device does not receive VRRP packets from the master device within the timeout interval, it considers that the master device fails, and then become the master.

CE series switches do not support setting of the VRRP protocol packet timeout interval. The VRRP packet timeout interval is calculated as follows: (3*Advertisement_Interval) + Skew_time. Advertisement_Interval is the interval for sending VRRP protocol packets. The default value is 1s. Skew_Time = (256-Priority)/256 , whose value can be 0 or 1. You can run the vrrp vrid timer advertise command to change the interval for sending VRRP protocol packets to adjust the timeout interval.

After the configuration is complete, the TimerConfig field in the command output of the display vrrp verbose command shows the configured interval for sending VRRP protocol packets.
