Redundancy Configuration
In an Alcatel network, the Access Points are controlled by an Alcatel Mobility
Controller. 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
Alcatel Mobility Controllers.
N
OTE—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 (4308 to 4308 or higher), and both switches should be run-
ning the same version of AOS-W.
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 net-
work 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.
