Understanding Command Modes
The command set is divided into Exec and Configuration classes. Exec commands generally display
information on system status or clear statistical counters. Configuration commands, on the other
hand, modify interface parameters or enable certain switching functions. These classes are further
divided into different modes. Available commands depend on the selected mode. You can always
enter a question mark “?” at the prompt to display a list of the commands available for the current
mode. The command classes and associated modes are displayed in the following table:
Exec Commands
When you open a new console session on the switch with the user name and password “guest,” the
system enters the Normal Exec command mode (or guest mode), displaying the “Console>”
command prompt. Only a limited number of the commands are available in this mode. You can
access all commands only from the Privileged Exec command mode (or administrator mode). To
access Privilege Exec mode, open a new console session with the user name and password
“admin.” The system will now display the “Console#” command prompt. You can also enter
Privileged Exec mode from within Normal Exec mode, by entering the enable command, followed by
the privileged level password “super.”
To enter Privileged Exec mode, enter the following user names and passwords:
Username: admin
Password: [admin login password]
CLI session with the BR6910 is opened.
To end the CLI session, enter [Exit].
Console#
Username: guest
Password: [guest login password]
CLI session with the BR6910 is opened.
To end the CLI session, enter [Exit].
