VRRP
The Avaya Multiservice Switch supports Virtual Router Redundancy
Protocol (VRRP), an IETF protocol designed to support redundant LAN
routers, as well as load balancing of traffic. VRRP is transparent to host end
stations. All configurations are done at the Avaya Multiservice Switch, no
additional end station configurations are required. See “

Hunt Groups
Ports within a hunt group by default are redundant to one another since hunt
groups perform load balancing among the ports. The hunt group load-shares
the traffic between two switches allowing the bandwidth to be multiplied.
The use of hunt groups also increases reliability since the links behave as
hot standby links to one another. If the traffic is shared over multiple links,
and one of the links is “lost”, the traffic will be automatically redistributed
over the other links and the communications will continue without
interruption. See “

Redundant Power
Supplies
Supplies
Only two power supplies are required to support a fully-loaded Avaya
Multiservice Switch. A third power supply can be installed to provide
backup should one of the other two fail. The power subsystem provides
N+1 power supply redundancy.
