About the NNCLI
This section describes the Nortel Networks Command Line Interface (NNCLI)
command modes you use to configure the Ethernet Routing Switch 8300 and the
commands you use to access the NNCLI. You can access the NNCLI using the
following methods:
•
Telnet session
•
rlogin
•
local console port
NNCLI command modes
The NNCLI has four major command modes, listed in order of increasing
privileges:
•
User EXEC
•
Privileged EXEC
•
Global configuration
•
Interface configuration
Each mode provides a specific set of commands. The command set of a
higher-privilege mode is a superset of a lower-privilege mode. That is, all
lower-privilege mode commands are accessible when using a higher-privilege
mode.
