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
      languagenone
      % set system policyServer localServer PSX_LOCAL_SERVER mode outOfService 
      % show system policyServer localServer PSX_LOCAL_SERVER
         state            enabled;  
         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
      languagenone
      % 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
      languagenone
      % 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
      languagenone
      % 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
    0product
    to communicate with a remote policy server that will not receive any query messages from the
    Spacevars
    0product
    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
    0product
    to PSXs not directly used by the
    Spacevars
    0product
    to route calls so that it may receive SCP-generated mid-call action events from those PSXs. 
    1. CLI:

      Code Block
      languagenone
      % 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.
