Cisco IOS User Interface

The following example shows the change from user EXEC mode to privileged EXEC mode.

Router> enable password: <password>

Router#

For information about using passwords, see the “Configuring Passwords” section on page 4-23.

Global Configuration Mode

Global configuration commands:

Apply to features that affect the system as a whole, rather than just one protocol or interface.

Use the configure terminal command to enter global configuration mode. From global configuration mode, you can access a number of other command modes.

Enable particular routing or bridging functions.

For information on protocol-specific global configuration commands, refer to the appropriate configuration guide in the Cisco IOS software documentation.

Interface Configuration Mode

Use interface configuration commands to modify the operation of an interface such as Ethernet, FDDI, or a serial port. Interface configuration commands always follow an interface global configuration command, which defines the interface type.

For details on interface configuration commands that affect general interface parameters such as bandwidth and clock rate, refer to the “Interface Commands” chapter in the Configuration Fundamentals Command Reference. For protocol-specific commands, refer to the appropriate Cisco IOS software command reference guide.
