Configuring Redundancy

The Avaya Multiservice Switch can be configured with redundancy

to provide fault tolerance.

The Avaya Multiservice Switch supervisor module manages the

resources of the switch, provides access to these resources and

supports a number of network protocols. These resources include

configuration information, spanning tree topology, address

forwarding tables, routing tables, and network statistics. Access is

provided to these resources via console CLI (command line

interface), Web interface, SNMP, and telnet.

The redundant supervisor module is an auxiliary "standby"

supervisor module that acts as a fault-tolerant supervisor in the

event that the "Active" supervisor fails. Once the redundant

supervisor is installed, loaded with the same software version as the

Active supervisor, and synchronized, it is ready to act as a redundant

or "standby" supervisor. If the Active supervisor does fail, the

redundant supervisor assumes control of network operation. No

user intervention is required for the Supervisor module failover. The

management view is accessible without changing IP or MAC

addresses. The event is logged and indicated via an SNMP trap.

Notification of this change is provided by a console message and an

event log message.

Up to two software versions can be saved on the Avaya Multiservice

Switch supervisor module.

The Avaya Multiservice Switch can be configured with a redundant

switch element module and a redundant switch controller module,

for backup of both switch fabric components. In the event of a

failure in a switch element or controller module, the redundant

module will take over the function of the failed component.
