The 

Spacevars
0 product

 can be configured to operate with up to nine active policy servers for load sharing and/or redundancy in a Centralized PSX routing scenario.

...

The

Spacevars
0 product

promotes a standby PSX to 'Active' status whenever one of the currently-active PSX goes out-of-service or becomes unreachable.

Procedure

This section provides examples of the steps an administrator uses from CLI and EMA to configure the

Spacevars
0 product

to communicate with external PSX policy servers in 'Active', 'Standby' or 'Alternate' modes.

Note
When configuring external PSXs for Centralized PSX routing, it is highly recommended to put the local policy server (ERE) out-of-service.

Info
The external PSX pool maximum is increased to 40.

1. Set the local policy server mode to "outOfService".

   1. CLI:

      Code Block
      language none
      % set system policyServer localServer PSX_LOCAL_SERVER mode outOfService % show system policyServer localServer PSX_LOCAL_SERVER state enableddisabled; mode outOfService; action dryUp; transactionTimer 2500; keepAliveTimer 5; retryTimer 2500; retries 1;

   2. On SBC main screen, navigate to Configuration > System Setup >Policy Server > Local Server. The Local Server window is displayed.

2. Set the global configuration.

1. CLI:

   Code Block
   language none
   % set system policyServer globalConfig reconnectTimeout 10 switchOverMode automatic congestionControl enabled type mgmt mgmtInterfaceGroup mgmtGroup % show system policyServer globalConfig reconnectTimeout 10; switchOverMode automatic; congestionControl enabled; type mgmt; mgmtInterfaceGroup mgmtGroup

    

2. On SBC main screen, navigate to Configuration > System Setup >Policy Server > Global Config. The Global Config window is displayed.

3.  To configure an external PSX as an Active remote policy server, use settings similar to the example below:

1. CLI:

   Code Block
   language none
   % set system policyServer remoteServer PSX1-A ipAddress 10.20.123.12 state enabled mode active % show system policyServer remoteServer PSX1-A ipAddress 10.20.123.12; state enabled; mode active;

2. On SBC main screen, navigate to Configuration > System Setup >Policy Server > Remote Server. The Remote Server window is displayed.

4. To configure an external PSX as a Standby remote policy server, repeat step 3 except set Mode to "standby".

1. CLI:

   Code Block
   language none
   % set system policyServer remoteServer PSX1-B ipAddress 10.20.123.13 state enabled mode standby % show system policyServer remoteServer PSX1-B ipAddress 10.20.123.13; state enabled; mode standby;

2. On SBC main screen, navigate to Configuration > System Setup >Policy Server > Remote Server. The Remote Server window is displayed.

5. To optionally configure

   Spacevars
   0 product

   to communicate with a remote policy server that will not receive any query messages from the

   Spacevars
   0 product

   but can still send messages to it, set the remote policy server mode to "alternate".
   
   This deployment model is intended for networks where PSXs are interacting with an SCP which may generate and deliver unsolicited mid-call action events to the SBX via the PSX. In other words, this model connects

   Spacevars
   0 product

   to PSXs not directly used by the

   Spacevars
   0 product

   to route calls so that it may receive SCP-generated mid-call action events from those PSXs. 

1. CLI:

   Code Block
   language none
   % set system policyServer remoteServer PSX2-A ipAddress 10.20.123.14 state enabled mode alternate % show system policyServer remoteServer PSX2-A ipAddress 10.20.123.14; state enabled; mode alternate;

2. On SBC main screen, navigate to Configuration > System Setup >Policy Server > Remote Server. The Remote Server window is displayed.
