Configuring a Web Interface:

Switches have web-based config tools that require an onboard HTTP server:
Web browser GUI.
Security Device Manager (SDM).
IP Phone and Telephony apps.
HTTP services ? security hole ? optional authentication.
If many users access HTTP services you may require a separate authentication server.
AAA and TACACS can be used to validate user credentials, (robust).
A less complex method allows use of the enable password.
A local authentication method requires the user to use a login username and password specified in the config.

S1(config)#ip http server ? turns on the server (on by default).
S1(config)#ip http authentication enable.
