n For priority: Set the master to 110; set the backup to 100 (the default value)
n Enable preemption
n Configure master up time or master state tracking with an add value of 20.
The following is a configuration example for the initially-preferred master.
(host)(config) #vrrp 22
vlan 22
ip address 10.200.22.254
priority 110
preempt
authentication password
description Preferred-Master
tracking master-up-time 30 add 20
no shutdown
The following configuration is the corresponding VRRP configuration for the peer switch.
(host)(config) #vrrp 22
vlan 22
ip address 10.200.22.254
priority 100
preempt
authentication password
description Backup-Master
tracking master-up-time 30 add 20
no shutdown
Use the following commands to associate the VRRP instance with master switch redundancy:
Command Explanation
master-redundancy
Enters the master-redundancy context.
master-vrrp <id>
Associates a VRRP instance with master redundancy. Enter
the virtual router ID of the VRRP instance.
peer-ip-address <ipaddr> ipsec <key>
Loopback IP address of the peer switch for master
redundancy.
The pre-shared key secures communication between the
master switches. Specify a key of up to 64 characters.
masterip <ipaddr> ipsec <key>
Configures the master IP address and pre-shared key on a
local switch for communication with the master switch.
Configure this to be the virtual IP address of the VRRP
instance used for master redundancy.
Table 140: VRRP Commands
Configure all the APs and local switches in the network with the virtual IP address as the master IP address. You can
configure the master IP address for local switches during the Initial Setup. The switch will require a reboot after
changing the master IP on the switch.
If DNS resolution is the chosen mechanism for the APs to discover their master switch, ensure that the name
“aruba-master” resolves to the same virtual IP address configured as a part of the master redundancy.
