Fix Recommendation

Configure the Cisco switch to log all configuration changes as shown in the following example:

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

Check Contents

Review the Cisco switch configuration to verify that it is compliant with this requirement. The configuration example below will log all configuration changes.

Step 1: Verify that account records will be sent to an AAA server as shown in the example below:

aaa accounting default group RADIUS_SERVERS

Step 2: Verify that the referenced group name has defined AAA servers that are online.

aaa group server radius RADIUS_SERVERS
server 10.1.48.10
server 10.1.48.12

Note: Cisco NX-OS devices report configuration activity to TACACS+ or RADIUS servers in the form of accounting records. Each accounting record contains accounting attribute-value (AV) pairs and is stored on the AAA server.

If the Cisco switch is not configured to log all configuration changes, this is a finding.
