NAM Software

Monitoring Traffic Through Internal Interface

Note The following restriction applies only to traffic that is monitored through the internal NAM interface.

The NAM Traffic Analyzer (web GUI) provides Layer 3 and higher layer information about the original packets. The Layer 2 header is modified by the router when it forwards the packets to the NAM, so the Layer 2 information that the NAM records is not applicable to the original packets.

NAM Software

The NAM software application resides on a network module that plugs into a host Cisco router running Cisco IOS software.

The network module is a standalone service engine with its own startup and run-time configurations that are independent of the Cisco IOS configuration on the router. The module does not have an external console port. Instead, you launch and configure the module through the router, by means of a configuration session on the module. After the session, you return to the router CLI and clear the session.

This arrangement—host router plus network module (the latter is also sometimes called an appliance or blade or, with installed software, a service or services engine)—provides a router-integrated application platform for accelerating data-intensive applications including the following and more:

•Application-oriented networking

•Contact centers and interactive-voice-response applications

•Content caching and delivery

•Data and video storage

•Network analysis

•Voice mail and auto-attendant applications
