On an Active SOAM, the Policy and Charging > Configuration > Online Charging DRA > CTFs page lists the CTF Peer Nodes for which the Session state is to be stored. This page is only used if Session State Scope is set to "Specific Messages" in the Network-Wide Options Configuration on the NOAM
The list of CTF Peer Nodes is updated by inserting, editing, deleting a CTF Peer Node from the Policy and Charging > Configuration > Online Charging DRA > CTFs page at each site's SOAM.
