Disabling Authentication of Local Management UserAccounts
You can disable authentication of management user accounts in local switches if the co nfiguredauthentication
server(s)(RA DIUS or TACACS+) are not available.
You can disable authentication of management usersbased on t he resultsreturned by the authentication server.
Whenconfigured, locally-definedmanagement accounts (for example, admin) arenot allowed to log in if the server
(s) are reachableand the user entry is not found in the authentication server.I n this situation, if the RADIUS or
TACACS+ server is unreachable,meaning it does not receive a response during authentication, or fails to
authenticate a userbecause of a timeout, local authentication is used and you can log in with a locally-defined
managementaccount.
