2.3 Auto Detect Implementation in VRRP

Note:
Currently, auto detect implementation in VRRP is only supported on S3900-EI series
switches.
You can control the priorities of VRRP backup groups according to auto detect results
to enable automatic switch between the master and the backup switch as follows:
Decrease the priority of a VRRP backup group when the result of the detecting
group is unreachable.
Resume the priority of a VRRP backup group when the result of the detecting
group is reachable.

2.3.1 Configuring the Auto Detect Function for VRRP

Note:
You need to create the detecting group and perform VRRP-related configurations
before the following operations.
