Installing the NAM

For information on physically installing the NAM into the router, see the Cisco Network Modules Quick Start Guide and the "Connecting Cisco Network Analysis Modules" chapter of Cisco Network Modules Hardware Installation Guide.

http://cco/univercd/cc/td/doc/product/access/acs_mod/cis2600/hw_inst/nm_inst/nm-doc/index.htm

Setting Up the NAM

The NAM has three interfaces for communication (Figure 1):

Analysis-Module Interface—Associated with the router.

Internal NAM Interface—Associated with the NAM.

External NAM Interface—Associated with the NAM.

This document shows you how to configure the Analysis-Module interface and internal NAM interface for managing and monitoring traffic. Alternatively, you can use the external NAM interface for managing and monitoring. However, this document does not cover that configuration. For more information on using the external NAM interface, see the Network Analysis Module (NM-NAM) feature module or the User Guide for the Network Analysis Module Traffic Analyzer Release 3.5.

The NM-NAM does not have an external console port. To access the NAM console, open a NAM console session from the router or use Telnet or SSH over the network. The lack of an external console port on the NM-NAM means that the initial boot configuration is possible only through the router.

After you install the NAM, you must do the following to begin using the Traffic Analyzer application:

Configuring the Analysis-Module Interface on the Router

Enabling Packet Monitoring

Accessing the NAM CLI

Configuring the NAM Management Network Parameters

Configuring the Analysis-Module Interface on the Router

To configure the Analysis-Module interface on the router CLI:


Step 1 Enter the interface configuration mode for the NAM.

interface analysis-module slot/port

Step 2 Assign an IP address by using the ip unnumbered command or by configuring a routable IP address and subnet mask on the internal interface.

a. If you use the ip unnumbered command:

ip unnumbered FastEthernet slot/port

b. If you use a routable IP address and subnet mask:

ip address 172.18.12.2 255.255.255.0


Note For the ip unnumbered command, make sure that a static route is configured on the router CLI for the NAM IP address that you configure through the NAM CLI in Step 2 of the "Configuring the NAM Management Network Parameters" section.



Note The following is a sample configuration:
ip route <nam-ip-address> 255.255.255.255 Analysis-Module slot/0



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.



Note For a detailed explanation, see: Configuring a Static Route to the NAM Through the Analysis-Module Interface at: http://www.cisco.com/en/US/products/sw/iosswrel/ps5413/products_feature
_guide09186a00801d6096.html#wp1046001


Step 3 Activate the NAM interface.

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.

ip cef

Step 2 Select an interface to configure.

interface type slot|wic-slot|port

Step 3 Enable NAM packet monitoring on the router interface.

analysis-module monitoring

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


Accessing the NAM CLI

The NM-NAM does not have an external console port. Console access to the NAM is established when you enter service-module analysis-Module slot/0 session in privileged EXEC mode on the router. The lack of an external console port on the NM-NAM means that the initial boot configuration can only be made through the router.


Step 1 Establish a console session with the NAM.

service-module analysis-module slot/0 session


Note If the Connection refused by remote host message is displayed, you must clear the existing session.


service-module analysis-module slot/0 session clear

Step 2 At the login prompt, enter root to log in to the root account.

Step 3 If you have not changed the password from the factory-set default, enter root as the root password.

Step 4 Perform the required tasks in the NAM CLI. For information on NAM CLI tasks, see the "Configuring the NAM Management Network Parameters" section. When you want to end the NAM console session and return to the Cisco IOS CLI, enter exit.


Note If you are in a subcommand mode, continue to enter the exit command until you see the NAM login prompt.


Step 5 Hold Ctrl-Shift and press 6. Release all keys, then press x to suspend and close the Telnet session.

Step 6 Enter disconnect to disconnect the line.


Note Some IOS versions require a session ID in the disconnect command, as in disconnect <session_id>, to disconnect the line.



Configuring the NAM Management Network Parameters

When you configure the internal NAM interface as the management interface, the IP address must be in the same subnet as the IP address of the Analysis-Module interface configured on the router CLI.


Step 1 Specify the internal NAM interface for handling management traffic.

ip interface internal

Step 2 Configure the NAM system IP address and subnet mask.

ip address ip-address subnet-mask

Step 3 Configure the NAM system broadcast address.

ip broadcast broadcast-address


Note This step is optional.


Step 4 Configure the NAM system default gateway address.

ip gateway ip-address

Step 5 Set the NAM system domain name.

ip domain name

Step 6 Set the NAM system host name.

ip host name

Step 7 Set one or more NAM system name servers.

ip nameserver ip-address


Note This step is optional but highly recommended. Unexpected delays can occur if a
name server is not set.


Step 8 Optionally check the connectivity to the device by pinging an external host or address.

ping host

or 

ping ip-address

Step 9 Verify that the device is properly configured.

show ip

Step 10 Enable the NAM Traffic Analyzer application.

ip http server enable

Step 11 Enter a web username and password.

Step 12 To access Traffic Analyzer, open a web browser and enter the NAM system IP address as the URL.
