You can also con?¬?gure a Cisco router using a remote-access application such as SSH.
For security purposes, the EXEC has the following two levels of access to commands:
?– User mode: Typical tasks include those that check the router status.
?– Privileged mode: Typical tasks include those that change the router con?¬?guration.
When you ?¬?rst log in to the router, a user-mode prompt is displayed. EXEC commands
available in user mode are a subset of the EXEC commands available in privileged mode.
These commands provide a means to display information without changing router
con?¬?guration settings.
To access the full set of commands, you must enable the privileged mode with the enable
command and supply the enable password, if it is con?¬?gured.
The EXEC prompt then displays as a pound sign (#) while in the privileged mode. From
the privileged level, you can access global con?¬?guration mode and the other speci?¬?c
con?¬?guration modes, such as interface, subinterface, line, router, route-map, and several
others.
Use the disable command to return to the user EXEC mode from the privileged EXEC
mode. Use the exit or logout command to end the current session. Figure 4-25 illustrates
the navigation through these modes.
