Why would a network administrator include a local username configuration, when the AAA-enabled router is also configured to authenticate using several ACS servers?

  • Because ACS servers only support remote user access, local users can only authenticate using a local username database.
  • A local username database is required when configuring authentication using ACS servers.
  • The local username database will provide a backup for authentication in the event the ACS servers become unreachable.
  • Without a local username database, the router will require successful authentication with each ACS server.

Explanation: The local username database can serve as a backup method for authentication if no ACS servers are available.
