Backup cannot changes its status due to lower priority than the Master when the Master fails.
Example: Configuring vrrp monitor interface to vlan 2 and decreasing amount of priority to 10.
Switch(Config-Router-Vrrp)# circuit-failover vlan 2 10
21.2 Typical VRRP Scenario
As shown in the figure below, SWITCHA and SWITCHB are Layer 3 Ethernet Switches in the
same group and provide redundancy for each other; SWITCHA is configured as the Master switch.

Configuration of SWITCHA:
SwitchA(config)#interface vlan 1
SwitchA (Config-If-Vlan1)# ip address 10.1.1.5 255.255.255.0
SwitchA (Config-If-Vlan1)#exit
SwitchA (config)#router vrrp 1
SwitchA(Config-Router-Vrrp)# virtual-ip 10.1.1.5 master
SwitchA(Config-Router-Vrrp)# interface vlan 1
SwitchA(Config-Router-Vrrp)# enable
Configuration of SWITCHB:
SwitchB(config)#interface vlan 1
SwitchB (Config-if-Vlan1)# ip address 10.1.1.7 255.255.255.0
SwitchB (Config-if-Vlan1)#exit
SwitchB(config)#router vrrp 1
SwitchB (Config-Router-Vrrp)# virtual-ip 10.1.1.5 backup
SwitchB(Config-Router-Vrrp)# interface vlan 1
SwitchB(Config-Router-Vrrp)# enable
