Cisco Cisco IOS Software Release 12.4(22)XR

Creates an entry in the cmTapStreamTable and sets the cmTapStreamStatus to active (1).

Sets cTap2StreamInterceptEnable to true(1) to start the intercept. The router intercepts traffic in the 
stream until the intercept expires (cTap2MediationTimeout). 

Due to its sensitive nature, the Cisco lawful intercept MIBs are only available in software images that 
support the lawful intercept feature. These MIBs are not accessible through the Network Management 
Software MIBs Support page (

). 

Only the mediation device and users who need to know about lawful intercepts should be allowed to 
access the lawful intercept MIBs. To restrict access to these MIBs, you must: 

Create a view that includes the Cisco lawful intercept MIBs.

Create an SNMP user group that has read-and-write access to the view. Only users assigned to this 
user group can access information in the MIBs. 

Add users to the Cisco lawful intercept user groups to define who can access the MIBs and any 
information related to lawful intercepts. Be sure to add the mediation device as a user in this group; 
otherwise, the router cannot perform lawful intercepts. 

Access to the Cisco lawful intercept MIB view should be restricted to the mediation device 
and to system administrators who need to be aware of lawful intercepts on the router. To 
access the MIB, users must have level-15 access rights on the router.

To perform the following procedures, SNMPv3 must be configured on the PDSN. For information about 
how to configure SNMPv3, and for detailed information about the commands described in the sections 
that follow, see the following Cisco documents:
