The Cisco Lawful Intercept feature is supported on the SaMOG (CGW, MRME) Gateway. Lawful Intercept is a license-

SaMOG has the ability to recover fully created sessions in the event of process level or card level failures.  

This feature supports the following types of session recovery: 



 

Task level recovery: SaMOG sessions are recovered when a Session Manager task serving the session is 

terminated due to a software error. 



 

Card level recovery: SaMOG sessions are recovered when the entire PSC/DPC card hosting the Session 

Manager fails, and all the tasks running on that card have to be recovered. The SaMOG sessions can be 
recovered in the event of a PSC/DPC card failures in the following scenarios: 



 

Unplanned card failure: SaMOG can recover tasks running on the failed card to the standby card by 

fetching the CRR information from the peer Session Managers and AAA Managers in the other card.
