Polycom CMA System Redundancy

This chapter describes how to configure a redundant Polycom

®

 Converged 

Management Application™ (CMA®) system. It includes these topics:
•

A redundant CMA system configuration offers higher reliability and greater 

call success by ensuring that a CMA system server is always available. 
A redundant CMA system configuration requires two CMA system servers 

and three IP addresses in the same subnet on the same network—one physical 

IP address for each of the servers and one virtual IP address dedicated to 

endpoint registration.

Terminology is very important in understanding how redundancy works.
In a redundant configuration, one server is licensed as the primary server and 

the other server is licensed as the redundant server. The primary server is 

always the primary server and the redundant server is always the redundant 

server. 
In a redundant configuration, there is only one active server. The active server 

is the server managing the system. It is the server running all of the CMA 

system services. In a normal operational state, the active server is the primary 

server. In a failover state, the active server is the redundant server.
