AMLS-NM-000430 - The Arista Multilayer Switch must employ AAA service to centrally manage authentication settings - aaa commands all start-stop
The use of authentication servers or other centralized management servers for providing centralized authentication services is required for network device management. Maintaining local administrator accounts for daily usage on each network device without centralized management is not scalable or feasible. Without centralized management, it is likely that credentials for some network devices will be forgotten, leading to delays in administration, which itself leads to delays in remediating production problems and in addressing compromises in a timely fashion.
Configure AAA services via a remote AAA server for all nonlocal accounts.
