Intercept-Related Events Transmitted to the Mediation Device
You can use SNMPv3 traps to report intercept-related events to the mediation device. These events include identifying information for subscribers, such as username or IP address, and subscriber session events, such as login or logout events or mirroring session activation or deactivation. The router sends the events to the mediation device in SNMP traps. Using SNMPv3 with privacy (encryption) configured provides secure traps that are visible only to authorized individuals on the intended secure mediation device. The traps help support compliance with the Communications Assistance for Law Enforcement Act (CALEA), which defines electronic surveillance guidelines for telecommunications companies.
The supported SNMPv3 traps map to messages defined by the Lawfully Authorized Electronic Surveillance (LAES) for IP Network Access, American Nation Standard For Telecommunications. SNMP Traps for Subscriber Secure Policy LAES Compliance describes the supported SNMPv3 traps and their related LAES messages.
