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.
