Configuring the switch
By default, the switch does not authenticate the console login user at an AUX interface. To increase
system security and enable remote management:
•
Configure remote access services, for example, Telnet or SSH.
•
Configure authentication on each user interface, including the AUX interfaces.
Configuring authentication on a user interface
You can configure authentication on a user interface to control access to the switch.
Table 8 describes the Telnet login authentication methods available for a VTY user line.
Table 8 Telnet login authentication methods
Authentication method Feature Application scenarios

management Environments that do not need
granular privilege management
Username and password
Complex to configure, secure, and
hierarchical user management
