Matrix PRASAR UCS System Manual 115
If you are configuring this parameter using the Backup Server IP Address,
• Select the Server Mode as Backup. This is the secondary server that responds to the client requests
only when the Primary Server is unavailable. It stays in sync with the Primary Server such that when
the Primary Server fails, the Backup Server has latest configuration and call information at the time of
redundancy.
If you have configured the same Server Mode in both the systems, then Redundancy will not be
supported.
• Description: Enter the location of the server. The description may consist of 24 characters (maximum).
For example, enter R&D.
• Redundancy On: Select the desired network — LAN or WAN, on which you want the redundancy to be
applied. Default: LAN.
• Redundancy LAN IP Address: Enter the IP Address assigned to the LAN Port of the system.
• Redundancy WAN IP Address: Enter the IP Address assigned to the WAN Port of the system.
Make sure that the Redundancy LAN and WAN IP Address are in the same subnet of IP addresses which
are configured in the Network Parameters.
• Isolation IP Address: This is the IP Address that is used by the Standby System to check whether it
isolated or not before applying redundancy.
When you select radio button of the Default Gateway, then the system uses the Gateway Address
configured in WAN Port of Network Parameters.
To assign a different IP address as the Isolation IP address, select the radio button and manually enter the
desired IP address.
• Make sure that the IP address to be configured as Isolation IP address is reachable through ‘Ping’. You
can check the status of this IP using “Network Diagnosis”.
• The Isolation IP address configured should be same for both Primary and Backup Server.
• Backup Server - Redundancy LAN IP Address: This is the IP address of the LAN port interface
connected to the Backup Server on which redundancy will be applied. This parameter is displayed when
you select Server Mode as Primary. Similarly, this is also valid for the WAN IP Address.
Primary Server - Redundancy LAN IP Address: This is the IP address of the LAN port interface
connected to the Primary Server on which redundancy will be applied. This parameter is displayed when
you select Server Mode as Backup. Similarly, this is also valid for the WAN IP Address.
• Call Manager - Synchronization Port: This port is responsible for synchronization between the Primary
Server and Backup Server. The Active server sends configuration to the Standby server through this port.
The value of this port is 254 and it is fixed.
• Session Manager - Synchronization Port: This port is responsible for synchronization between the
Primary Server and Backup Server. The Active server sends configuration to the Standby server through
this port. The value of this port is 873 and is fixed.
