Fix Recommendation

In the APIC, configure redundant RADIUS providers.
1. On the menu bar, choose Admin >> AAA.
2. In the Navigation pane, choose "Authentication".
3. In the Work pane, choose "Providers", and then click Actions >> Create Provider.
4. In the Create Provider screen, enter the Hostname/IP Address, Description, and choose a RADIUS or TACACS+ as the realm from the drop-down list. Provide the configuration details.
5. Repeat the above steps for at least one other AAA server.

Create the login domain for RADIUS:
1. In the Navigation pane, choose AAA Authentication >> Login Domains.
2. In the Work pane, choose Actions >> Create Login Domain.
3. Specify the login domain name, description, realm, and provider group as appropriate.

Note: The above configuration is an example using the RADIUS protocol; however, DOD sites may configure the options for RADIUS or TACACS+.
