Rules for redundant server implementations
In a redundant server configuration, mobile clients access the active server, and not the inactive backup server. The two servers switch roles freely, and the following rules determine the
INACTIVE:
•If you do not enter a backup IP address in the MCG 3100 Web Console, the server starts in ACTIVE mode.
•If you enter a backup IP address in the MCG 3100 Web Console, the server starts in STANDBY mode and attempts to locate the backup server.
•If the backup server is found in STANDBY mode, the server with the lower IP address is declared ACTIVE.
•If the backup server is found in ACTIVE mode, the backup server remains ACTIVE.
•If the backup server is not found within approximately 45 seconds, the local server is declared ACTIVE.
•If the ACTIVE server stops, the STANDBY server becomes ACTIVE after approximately 45 seconds.
ATTENTION
If the MCG 3100 server fails, the Administration Server and Group Call Server fail also.
