Logging In For the First Time

After you turn power on and boot the Cisco Prime NAM 2300 series appliance for the first time, the login prompt displays on the attached console. When shipped from the factory, the root user is preconfigured on the Cisco Prime NAM 2300 series appliance. The default password for the root user is root.

Note You must change the user root password during the first login session.

The root user has access to the root (read/write) level of NAM and can enter NAM command-line interface (CLI) commands.

To log in to the Cisco Prime NAM 2300 series appliance for the first time, open a console session or a serial session with the NAM appliance. This example opens a session with the Cisco Prime NAM 2320:

Note After your initial login, you can enable telnet and ssh connections to the NAM appliance.

Step 1 When the NAM login prompt appears, type root and press Enter.

nam.localdomain login : root

Step 2 When the password prompt appears, type root and press Enter.

After you enter the ID and password, you will be prompted to change the root password.

Step 3 Enter the new password for the root user, then enter it a second time.

We recommend that you make a record of the password, and store this information in a secure location. You should change this password regularly in accordance with your site’s password security policies. See Changing the Root Password.

Changing the Root Password

This section describes how to change the root user password after the initial login session. To change the root password:

Step 1 Open a console session or serial session with the NAM appliance.

Step 2 When prompted for a username, enter root.

The Cisco Prime NAM 2300 series appliance ships from the factory with default settings for user root with a password of root.

Step 3 When prompted, enter the password for user root.

After you log in as the root user, you have read and write access to the root level of the NAM appliance, and you can enter and perform CLI commands.

Step 4 Enter the following command to change the root user password.

password root

Step 5 Enter the new password for user root and confirm it.

We recommend that you make a record of the password and store this information in a secure location. You should change this password regularly in accordance with your site’s password security policies.

Step 6 Type exit to end the session and log out.

Resetting the NAM Root Password to the Default Value

For information about how to reset the NAM root password to the default value, see the Cisco Prime Network Analysis Module Software User Guide.

Establishing Network Connectivity

This section describes how to configure a Cisco Prime NAM 2300 series appliance to configure IP parameters and establish network connectivity.

Log in to a Cisco Prime NAM 2300 series appliance from the management console and enter the following CLI commands with the appropriate information for your site:

Step 1 Use the ip address command to configure the NAM appliance IP address. The syntax for this command is as follows:

ip address ip-address subnet-mask

Example

root@localhost# ip address 172.20.104.126 255.255.255.248

Step 2 You can use the ip broadcast command to configure the NAM appliance broadcast address. The syntax for this (optional) command is as follows:

ip broadcast broadcast-address

Example

root@localhost# ip broadcast 10.255.255.255

Step 3 Use the ip gateway command to configure the NAM appliance default gateway address. The syntax for this command is as follows:

ip gateway ip-address

Example

root@localhost# ip gateway 172.20.104.123

Step 4 You can use the exsession command to enable remote login to the NAM appliance using either Telnet or SSH. The syntax for this (optional) command is as follows:

exsession on (for Telnet)

or

exsession on ssh (for SSH)

Examples

To configure the NAM appliance to enable Telnet access:

root@localhost# exsession on

To configure the NAM appliance to enable SSH access:

root@localhost# exsession on ssh

Step 5 You can use the ip domain command to configure the NAM appliance system domain name. The syntax for this (optional) command is as follows:

ip domain name

Example

root@localhost# ip domain your_company.com

Step 6 You can use the ip host command to configure the NAM appliance system hostname.

The syntax for this command is as follows:

ip host name

Example

root@localhost# ip host nam_machine

Step 7 You might (optionally) want to use the ip nameserver command to configure one or more name servers for the NAM appliance.

The syntax for this command is as follows:

ip nameserver ip-address [ip-address] [ip-address}

Examples

root@localhost# ip nameserver 172.20.104.10

root@localhost# ip nameserver 172.20.104.10 172.20.104.20 172.20.104.30

Checking Your Configuration

After you finish configuring the NAM appliance for network connectivity, it is a good idea to check your connectivity and verify the IP parameters you have just configured for the NAM appliance.

Step 1 Use the ping command to check connectivity between the NAM appliance and a network device.

The syntax for this command is as follows:

ping {hostname | ip-address}

Examples

root@localhost# ping nam_machine.your_company.com

root@localhost# ping 172.20.104.10

The following is an example of the ping command showing successful connectivity:

Step 2 Use the show ip command to verify that you have configured the NAM appliance IP parameters the way you want them.

The syntax for this command is as follows:

show ip

The following is an example of the show ip command output that shows a configured NAM appliance:

Verifying System Status

To verify the status of an installation, upgrade, or downgrade or to troubleshoot problems, use commands from those listed in Table 3-1 , Common Diagnostic and Show Commands .

Note ● The tables in these sections show only common managed device and network module commands.

– To view a complete list of available commands, type ? at the prompt
(Example: user@nam_host.domain# ?).

– To view a complete list of command keyword options, type ? at the end of the command
(Example: nam_host.domain# ip ?).

• The tables group commands by the configuration mode in which they are available. If the same command is available in more than one mode, it might act differently in each mode.

Note Many show commands include the keyword option to display diagnostic output on your screen or to pipe it to a file or a URL.

Enabling the NAM Web Server

This section describes how to enable the NAM web server and browser-based access to the NAM graphical user interface (GUI).

Note You can enable the NAM to function as an HTTP server or an HTTPS secure server, but not as both simultaneously.

To enable the NAM web server and provide browser-based access, confirm that your web browser supports your NAM software release.

Note For a list of supported browsers, see the NAM software release notes.

To enable the NAM web server:

Step 1 Open a Telnet or SSH session to the NAM appliance and at the password prompt, enter your password.

telnet {ip-address | hostname}

or

ssh {ip-address | hostname}

Step 2 Enter one of the following commands to enable either an HTTP server or an HTTPS secure server:

To enable the NAM HTTP web server:

ip http server enable

To enable the NAM HTTPS secure web server:

ip http secure server enable

The NAM requests a web administrator user name.

The NAM web server requires at least one properly-configured web administrator. If the NAM does not prompt you for a web username and password, then at least one web administrator was previously configured.

Step 3 Enter the username of the web administrator. Otherwise, press Enter to use the default web administrator username admin.

The NAM requests a password for the web administrator, then requests the password to be entered again to ensure accuracy.

Step 4 Enter the password for the web administrator and confirm it. Otherwise, press Enter to use the default web administrator password adminpswd.

Note Because this document is available to the public by way of Cisco.com, it is a good idea to change this and all default passwords as soon as possible.

Step 5 To check the NAM web server functionality, launch an approved internet browser and enter the IP address or host and domain name in the browser address field.

Note For a list of supported browsers, see the NAM software release notes.

If the Cisco Prime NAM 2300 series appliance web server is properly configured, you should access the NAM login window.

At this point, the only user able to log in to the NAM web server is the administrative user you configured when you enabled the web server.

Configuring a Monitored Device

After you connect an output interface of a monitored (or managed) device to the monitoring ports of the Cisco Prime NAM 2300 series appliance, you must also configure the monitored device to send data to that interface. You do this in two steps:

• Configuring a Monitored Device Interface
• Span the port of the monitored device to use the Cisco Prime NAM 2300 series appliance as a destination port

Opening and Closing a Telnet or SSH Session to the NAM

This procedure opens and closes a Telnet or SSH session to the NAM. This procedure is not commonly performed, because you would typically use the NAM GUI to monitor and maintain the NAM. If, however, you cannot access the NAM GUI, you might want to use Telnet or SSH to troubleshoot from the NAM CLI.

If your Cisco Prime NAM 2300 series appliance is not properly configured for Telnet or SSH access (see the following Prerequisites section), you can open a Telnet session to the managed device to which the Cisco Prime NAM 2300 series appliance is connected, then open a NAM console session from the managed device.

Prerequisites

• Configure the NAM system IP address. Optionally, set the NAM system hostname.
• Verify NAM network connectivity by performing one of the following ping tests:

– From a host beyond the gateway, ping the NAM system IP address.

– From the NAM CLI, ping the NAM system default gateway.

Telnet Prerequisites

• Enter the exsession on NAM CLI command.

SSH Prerequisites

• Enter the exsession on ssh NAM CLI command.

Summary Steps

1. telnet { ip-address | hostname }
or
ssh { ip-address | hostname }

2. At the login prompt, enter root.

3. At the password prompt, enter your password.
or
If you have not changed the password from the factory-set default, enter root as the root password.

4. Perform the tasks that you need to perform in the NAM CLI. When you want to end the Telnet or SSH session to the NAM and return to the Cisco IOS CLI, complete Step 5 and Step 6.

5. exit

6. logout
