Redundancy Configuration
In an Aruba network, the Access Points are controlled by an Aruba WLAN Switch. The APs
tunnel all data to the switch that does all the processing of the data, including
encryption/decryption, bridging/forwarding etc.
Local switch redundancy refers to providing redundancy for this switch such that the APs
“failover” to a backup switch if a switch becomes unavailable. Local switch redundancy is
provided by running VRRP between a pair of Aruba WLAN Switches.

The two switches need to be connected on the same broadcast domain (or layer-2
connected) for VRRP operation. The two switches should be of the same class (A800 to
A800 or higher), and both switches should be running the same version of AirOS.
The Access Points are now configured to connect to the “virtual-IP” configured on the VRRP
instance.
Configuring Local Switch Redundancy
To configure redundancy for a local switch:
1 Collect the following information needed to configure local switch redundancy:
z
VLAN ID on the two local switches that are on the same layer 2 network and will be
used to configure VRRP.
z
Virtual IP address that has been reserved to be used for the VRRP instance.
2 Navigate to the
Configuration > Switch > VRRP
page on the WebUI for each of the
local switches. Click
Add
to start creating a VRRP instance.
