What to Do Next

If you plan to monitor traffic through the internal NAM interface, then proceed to the “Enabling NAM Packet Monitoring” section on page 37.

If you do not plan to monitor traffic through the internal NAM interface, then proceed to the “Enabling and Accessing the NAM Traffic Analyzer” section on page 40.

Enabling NAM Packet Monitoring

This section describes how to enable NAM packet monitoring on router interfaces that you want to monitor through the internal NAM interface.

When you enable NAM packet monitoring on an interface, Cisco Express Forwarding sends an extra copy of each IP packet that is received from or sent out on that interface to the NAM through the Integrated-Service-Engine interface on the router and the internal NAM interface.
