session-agent cac-trap-threshold is not working

Hello,

I was trying to activate the parameter "cac-trap-threshold" under the session-agent configuration so I could have a trap when a specific session-agent exceeds a certain number of sessions.

I tried with:

allow-next-hop-lp enabled

constraints enabled

        max-sessions 660

max-inbound-sessions 660

max-outbound-sessions 660

max-burst-rate 0

max-inbound-burst-rate 0

max-outbound-burst-rate 0

max-sustain-rate 0

max-inbound-sustain-rate 0

max-outbound-sustain-rate 0

min-seizures 5

min-asr 0

cac-trap-threshold 3

and it's not working (and the session-agents sessions are higher than 3%).

Does anyone know if I need any extra configuration?

Under system-config:

snmp-enabled                            enabled

        enable-snmp-auth-traps                  enabled

        enable-snmp-syslog-notify               enabled

        enable-snmp-monitor-traps               enabled

        enable-env-monitor-traps                enabled

        snmp-syslog-his-table-length            1

        snmp-syslog-level                       WARNING

Thank you
