Cisco Cisco IOS Software Release 12.2(33)SB

The Lawful Intercept feature supports the Communications Assistance for Law Enforcement 
Act (CALEA), which describes how service providers in the United States must support lawful intercept. 
Currently, lawful intercept is defined by the following standards: 

Telephone Industry Association (TIA) specification J-STD-025 

Packet Cable Electronic Surveillance Specification (PKT-SP-ESP-101-991229)

For information about Cisco’s lawful intercept solution, contact your Cisco account representative. 

Refer to 

 for details on lawful intercept capabilities by Cisco IOS release. 

Lawful intercept has the following benefits:

Allows multiple LEAs to run a lawful intercept on the same target without each other’s knowledge. 

Does not affect subscriber services on the router. 

Cannot be detected by the target. 

Allows LEAs to perform lawful intercepts without the knowledge of service providers. 

Uses Simple Network Management Protocol Version 3 (SNMPv3) and security features like the 
View-based Access Control Model (SNMP-VACM-MIB) and User-based Security Model 
(SNMP-USM-MIB) to restrict access to lawful intercept information and components. 

Hides information about lawful intercepts from all but the most privileged users. An administrator 
must set up access rights to enable privileged users to access lawful intercept information. 

Provides two secure interfaces for performing an intercept: one for setting up the wiretap and one for 
sending the intercepted traffic to the mediation device.

In Cisco IOS Release 12.2(31)SB2 and later releases, intercept taps are supported on the following 
PPPoX sessions using Layer 2 RADIUS-based taps: 

PPPoA 

PPPoE 

PPPoEoA 

PPPoEoVLAN 

PPPoEoQinQ
