Note On the NAM, the IP address must belong to the subnet of the parent interface for the

Analysis-Module slot/0 (such as fa0/0). The NAM default gateway should be the parent

interface IP.

Step 3 Activate the NAM interface.

Router (config-if)# no shutdown

Enabling Packet Monitoring

When you use the internal NAM interface for monitoring traffic, you must enable NAM packet

monitoring on each router interface that you want to monitor. NAM packet monitoring uses Cisco

Express Forwarding (CEF) to send a copy of each packet that is received in or sent out of the router

interface to the NAM.

Step 1 Enable the CEF switching path.

Router(config)# ip cef

Step 2 Select an interface to configure.

Router (config)# interface type slot|wic-slot|port

Step 3 Enable NAM packet monitoring on the router interface.

Router (config-if)# analysis-module monitoring

Step 4 Repeat Step 2 and Step 3 for each interface the NAM should monitor.
