Preface

This guide describes the implementation of the Lawful Intercept feature on Catalyst 6500 series switches.

Lawful intercept is a process that enables a Law Enforcement Agency (LEA) to perform electronic surveillance on an individual as authorized by a court order. To assist in the surveillance, the service provider intercepts the target's traffic as it passes through one of their routers, and sends a copy of the intercepted traffic to the LEA without the target's knowledge.

Audience

This guide is intended for system administrators who must configure the router to support lawful intercept. This guide may also be useful for application developers who are developing management applications for use with lawful intercept.

Organization

This guide contains the following chapters:

•Chapter 1, "Lawful Intercept Overview," provides background information about lawful intercept and its implementation. It also describes the CISCO-TAP2-MIB and CISCO-IP-TAP-MIB, which are used for lawful intercept. A Management Information Base (MIB) enables the router to be controlled through the Simple Network Management Protocol (SNMP).

•Chapter 2, "Configuring Lawful Intercept Support," provides instructions for configuring the router to support lawful intercept.
