526 CHAPTER 37: CONFIGURING TERMINAL ACCESS SECURITY
By default, no user is configured.
Configuring User Login
Authentication All users who access a router through a terminal are called terminal users. 3Com
routers divide terminal users into five types:
■Asynchronous port terminal user
■X.25 PAD calling user
■Console port user
■Dumb terminal user
■Telnet terminal user
3Com routers now support command line interpreters that access terminals from
four types of interfaces:
■Remote X.25 PAD
■Asynchronous dialing port (working in interactive mode)
■Local console port
■Dumb terminal access mode
■Local/remote Telnet terminal
Perform the following configurations in system view.
