Chapter 11 Configuring Interface Characteristics

Using Interface Configuration Mode

Step 3 Follow each interface command with the interface configuration commands that the interface requires. The commands that you enter define the protocols and applications that will run on the interface. The commands are collected and applied to the interface when you enter another interface command or enter end to return to privileged EXEC mode.

You can also configure a range of interfaces by using the interface range or interface range macro global configuration commands. Interfaces configured in a range must be the same type and must be configured with the same feature options.

Step 4 After you configure an interface, verify its status by using the show privileged EXEC commands listed in the “Monitoring and Maintaining the Interfaces” section on page 11-38.

Enter the show interfaces privileged EXEC command to see a list of all interfaces on or configured for the switch. A report is provided for each interface that the device supports or for the specified interface.

Configuring a Range of Interfaces

You can use the interface range global configuration command to configure multiple interfaces with the same configuration parameters. When you enter the interface-range configuration mode, all command parameters that you enter are attributed to all interfaces within that range until you exit this mode.

Beginning in privileged EXEC mode, follow these steps to configure a range of interfaces with the same parameters:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface range {port-rangemacro	Specify the range of interfaces (VLANs or physical ports) to be
	macro_name}	configured, and enter interface-range configuration mode.
		• You can use the interface range command to configure up to five
		port ranges or a previously defined macro.
		• The macro variable is explained in the “Configuring and Using
		Interface Range Macros” section on page 11-19.
		• In a comma-separated port-range, you must enter the interface
		type for each entry and enter spaces before and after the comma.
		• In a hyphen-separated port-range, you do not need to re-enter the
		interface type, but you must enter a space before the hyphen.
Step 3
		Use the normal configuration commands to apply the configuration
		parameters to all interfaces in the range. Each command is executed
		as it is entered.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	show interfaces [interface-id]	Verify the configuration of the interfaces in the range.
Step 6
	copy running-config startup-config	(Optional) Save your entries in the configuration file.
