Topology hiding configuration is performed at both the network level using the NOAM GUI and at the site level using the SOAM GUI.
The fields are described in Policy Clients elements.
On the SOAM GUI, use the Policy and Charging > Configuration > Policy DRA > Policy Clients to define the list of Policy Client Peer Nodes from which the PCRF name is to be hidden. This page can be used only if Topology Hiding is Enabled and the Topology Hiding Scope option is either Specific Clients or All Foreign Realms + Specific Clients on the Policy and Charging > Policy DRA > Configuration > Network-Wide Options page on the NOAM GUI. See Site Options for additional information.
The Policy and Charging > Configuration > Policy DRA > Policy Clients [Insert] page opens. You can add a Policy Client Peer Node Name and Comment. See Adding a new Policy Client for Topology Hiding. If the maximum number of Policy Client Peer Nodes (1000) already exists in the system, the Policy and Charging > Configuration > Policy DRA > Policy Clients [Insert]page will not open, and an error message is displayed.
The Policy and Charging > Configuration > Policy DRA > Policy Clients [Edit] page opens. You can edit the Comment for the selected Policy Client Peer Node Name. (The Policy Client Peer Node Name cannot be changed). See Editing Policy Clients for Topology Hiding.
