ip https authentication Use the ip https authentication command in Global Configuration mode to specify authentication methods for https server users. To return to the default configuration, use the no form of this command. Syntax ip https authentication method1 [method2...] no ip https authentication Parameter Description method1 [method2...] - Specify at least one from the following table: Keyword local none radius tacacs Source or destination Uses the local username database for authentication. Uses no authentication. Uses the list of all RADIUS servers for authentication. Uses the list of all TACACS+ servers for authentication. Default Configuration The local user database is checked. This action has the same effect as the command ip https authentication local. Command Mode Global Configuration mode User Guidelines The additional methods of authentication are used only if the previous method returns an error, not if it fails. To ensure that the authentication succeeds even if all methods return an error, specify none as the final method in the command line. If none is specified as an authentication method after radius, no authentication is used if the RADIUS server is down. AAA Commands 255
