Controller Based WLANs

Introduction : In the case of all standalone master controllers, we need to designate a controller as the license server and another controller as the redundant license server.
 
VRRP configuration will be used to create the redundant license server.  This means that the two license servers must be co-located in the same L2 domain.

Feature Notes : Centralized licensing feature is disabled by default.

Environment : Aruba OS 6.3 and above.

Network Topology : In this configuration example we have four standalone master controllers namely Standalone1, Standalone2, Standalone3, Standalone4.
 
We are choosing the Standalone1 (192.168.1.2) as the license server and Standalone2 (192.168.1.3) as the redundant license server.
 
There is a vrrp instance (vrrp 100) running between Standalone1 and Standalone2. Virtual IP is 192.168.1.1.

Configuration Steps :

Configuration required on the license server:
=====================================
 
(Standalone1) (config) #license profile
(Standalone1) (License provisioning profile) #centralized-licensing-enable
 
(Standalone1) (config) #license server-redundancy
(Standalone1) (config-license-server-redundancy)#license-vrrp 100
(Standalone1) (config-license-server-redundancy)#peer-ip-address 192.168.1.3
 
(Standalone1) (config) #show license server-redundancy
 
License Server redundancy configuration:
License VRRP Id 100 current state is MASTER
License Peer's IP Address is 192.168.1.3

Configuration required on the redundant license server:
===============================================
 
(Standalone2) (config) #license profile
(Standalone2) (License provisioning profile) #centralized-licensing-enable
 
(Standalone2) (config) #license server-redundancy
(Standalone2) (config-license-server-redundancy)#license-vrrp 100
(Standalone2) (config-license-server-redundancy)#peer-ip-address 192.168.1.2
 
(Standalone2) (config) #show license server-redundancy
 
License Server redundancy configuration:
License VRRP Id 100 current state is BACKUP
License Peer's IP Address is 192.168.1.2

Configuration required on the license clients:
=====================================
 
(Standalone3) (config) #license profile
(Standalone3) (License provisioning profile) #centralized-licensing-enable
(Standalone3) (License provisioning profile) #exit
(Standalone3) (config) #license server-ip 192.168.1.1
 
(Standalone4) (config) #license profile
(Standalone4) (License provisioning profile) #centralized-licensing-enable
(Standalone4) (License provisioning profile) #exit
(Standalone4) (config) #license server-ip 192.168.1.1
