You can select the session scaling profile for your specific configuration. The session scaling profile determines how much memory is allocated for your user sessions in wireless control and user plane
separation (CUPS). If you don't select a session scale, Junos OS uses the maximum available scale size for your device. When the number of sessions reaches 80%, 90%, and 100% of the active scaling profile, Junos OS
sends telemetry and ERRMSG notifications to you. At 100% usage, Junos OS rejects new sessions..
