Remote Server Parameters

Parameter

Length/Range

Description

Name

Up to 23 characters

Enter the name of the remote policy server.

IP Address V4 or V6

Up to 32 characters

Enter the IPv4 or IPv6 address of the PSX Server.


FQDN

0-256


This functionality is currently only available in an OpenStack cloud environment.

Enter the Policy Server FQDN value.

You can configure the PSX cluster FQDN in an SBC instance or seed it in the SBC instance during instantiation. The SBC instance learns a list of IP addresses of remote policy server instances in a PSX cluster by resolving the PSX cluster's FQDN with the help of the DNS server. This enables SBC to talk to multiple PSX instances of a PSX cluster by simply providing the FQDN of the PSX cluster.

NOTE: The user can configure the remote policy server's (PSX) FQDN or IP address but cannot configure both simultaneously.

Refer to SBC Support of Multiple PSX Clusters Using PSX Cluster FQDN for feature details.

Max Policy Server Count

1-40


This functionality is currently only available in an OpenStack cloud environment.

Choose the maximum number of policy server clients to create using the IP addresses picked from the DNS results under the remote server configuration (default = 1).

NOTE: This parameter is only visible when FQDN is configured/used.

Transaction
Timer

50-60000
