I’m going to walk through the steps for configuring master redundancy. Here is my scenario:
Primary Master – 10.10.10.11 (should always be the master if up)
Backup Master – 10.10.10.12
VRRP IP – 10.10.10.15
VRRP ID – 10
VLAN – 10
First let’s start with the VRRP configuration on the Primary Master.
config t vrrp 10 vlan 10 ip address 10.10.10.15 priority 110 preempt description Preferred-Master tracking master-up-time 30 add 20 no shut
Now let’s configure the Backup-Master
config t vrrp 10 vlan 10 ip address 10.10.10.15 priority 100 preempt description Backup-Master tracking master-up-time 30 add 20 no shut
Once VRRP is up I need to associate the VRRP instance with master controller redundancy:
On the Primary:
config t master-redundancy master-vrrp 10 peer-ip-address 10.10.10.12 ipsec aruba123
On the Backup:
config t master-redundancy master-vrrp 10 peer-ip-address 10.10.10.11 ipsec aruba123
Once the VRRP instance is associated with master redundancy then I need to synchronize the WMS and local user database between the two controllers:
config t database synchronize period <minutes> – defines the scheduled time to sync the databases (minimum should be 20 minutes)
