Master Switch Redundancy
The Master switch in the Alcatel solution acts as a single point of configuration
for global policies such as firewall policies, authentication parameters, RF
configuration to ease the configuration and maintenance of a wireless
network. It also maintains a database related to the wireless network that is
used to make any adjustments (automated as well as manual) in reaction to
events that cause a change in the environment (such as an AP becoming
unavailable). The Master switch is also responsible for providing the
configuration for any AP to complete its boot process. If the Master becomes
unavailable, the network continues to run without any interruption. However
any change in the network topology or configuration will require the availability
of the Master switch.
To maintain a highly redundant network, the administrator can use a switch to
act as a hot standby for the Master switch. The underlying protocol used is the
same as in local redundancy, that is VRRP.
To configure master switch redundancy:
1. Collect the following data before configuring master switch redundancy.
z VLAN ID on the two 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 Connect to the switch CLI using Telnet or SSH. After logging into the
switch, enter the global configuration mode.
To configure VRRP on the VLAN ID.
