What is Aruba Virtual Controller?

--> Aruba Instant Access Points does not require any external wireless controller to manage the WIFI network.

--> Any Aruba Instant Access Point can dynamically take up the role of the virtual controller without impacting the network.

--> Virtual controller contains all the settings similar to the physical wireless controller to provide centralized functionality to manage the WIFI network.

--> Aruba Instant access points uses Master Election Protocol to dynamically elect an Instant Access Point as Virtual Controller.




--> If the elected Virtual controller goes down then the new virtual controller is selected based on the Master Election Protocol.

--> Once an Instant Access Point becomes Virtual Controller then it sends three ARP messages with static IP Address and MAC address to update the network.

--> Having Virtual controller in the network provides following benefits,

i) Scalability

ii) No Hardware Controller is required

iii) Redundancy

iv) No License

v) Less Cost
