Disabling Authentication of Local Management User Accounts
You can disable authentication of management user accounts in local switches if the configured authentication
server(s) (RADIUS or TACACS+) are not available.
You can disable authentication of management users based on the results returned by the authentication server.
When configured, locally-defined management accounts (for example, admin) are not allowed to log in if the
server(s) are reachable and the user entry is not found in the authentication server. In this situation, if the
RADIUS or TACACS+ server is unreachable, meaning it does not receive a response during authentication, or
fails to authenticate a user because of a timeout, local authentication is used and you can log in with a locally-
defined management account.
In the WebUI
1. Navigate to the Configuration > Management > Administration page.
2. Under Management Authentication Servers, uncheck the Local Authentication Mode checkbox.
3. Click Apply.
