The NBAR2 HTTP-based Visibility Dashboard provides a graphical display of network information, such as network traffic details and bandwidth utilization. The Visibility Dashboard includes interactive charts and a graph of bandwidth usage.

The basic workflow for using the Visibility Dashboard is:

1. Using the procedure described in Configuring NBAR2 HTTP-Based Visibility Dashboard, configure the router to provide information for the Visibility Dashboard. This includes:

   • Enabling an HTTP server.

   • Setting up the router service that collects and stores traffic data.

   • Specifying an interface to monitor.

   • Enabling protocol discovery.

2. In a browser, connect to the Visibility Dashboard web interface to display traffic information for the monitored interface(s), using the router IP address or hostname, and appending /flash/nbar2/home.html .

   Example: 10.56.1.1/flash/nbar2/home.html

   See Accessing the Visibility Dashboard.

3. The HTTP server that operates with the Visibility Dashboard requires HTTP command access to the router to collect traffic data to present in the dashboard. Specifically, the HTTP server executes show ip nbar CLI commands on the router to collect the data. Access is provided to the Visibility Dashboard HTTP server by one of the following methods:

   • Providing "privilege 15" general access to the router.

     Use the ip http authentication enable CLI command on the router to set a password. When logging into the Visibility Dashboard web interface, use the specified password. No username is required.

   • Setting a local username and password for the router.

     Use the ip http authentication local command to set a local username/password providing HTTP command access. When logging into the Visibility Dashboard web interface, enter the specified username and password.

     Example configuration:

     Device(config)#ip http authentication enable
     Device(config)#ip http authentication local 
     Device(config)#username cisco
     Device(config)#password n449rbpsvq
     
     

   • Using an Authentication, Authorization, and Accounting (AAA) server.

     The AAA server manages accounts, including username/password credentials. When logging into the Visibility Dashboard web interface, enter the username and password for an account managed by the AAA server.

     Note: The account must include authorization to execute show ip nbar commands on the router. If the account does not provide this authorization, a user could log in and pass authentication, but no traffic data would be available from the router. The Visibility Dashboard would appear in the browser, but showing no information.

In a browser with access to the router, connect to the Visibility Dashboard web interface to display traffic information for the monitored interface(s), using the router IP address or hostname, and appending /flash/nbar2/home.html . This string is shown in the CLI help for ip nbar http-services by typing: ip nbar ?

Options:

• http://<router-IP-address>/flash/nbar2/home.html

• http://<router-hostname>/flash/nbar2/home.html

Example:

http://10.56.1.1/flash/nbar2/home.html
