Details

This requirement supports non-repudiation of actions taken by an administrator and is required in order to maintain the integrity of the configuration management process. All configuration changes to the network device are logged, and administrators authenticate with two-factor authentication before gaining administrative access. Together, these processes will ensure the administrators can be held accountable for the configuration changes they implement.

To meet this requirement, the network device must log administrator access and activity.

Solution

Configure the switch to log administrator activity as shown in the steps below:

Step 1: Configure the AAA servers as shown in the example below:

SW1(config)# radius-server host 10.1.48.10
SW1(config)# radius-server host 10.1.48.12

Step 2: Configure an AAA server group as shown in the example below:

SW1(config)# aaa group server radius RADIUS_SERVERS
SW1(config-radius)# server 10.1.48.10
SW1(config-radius)# server 10.1.48.12
SW1(config-radius)# exit

Step 3: Enable AAA accounting as shown in the example below:

SW1(config)# aaa accounting default group RADIUS_SERVERS
SW1(config)# end
