Chapter 10 Configuring Interface Characteristics
Using the Interface Command
Note You do not need to add a space between the interface type and interface number. For example,
in the preceding line, you can specify either gigabitethernet 0/1, gigabitethernet0/1, gi 0/1, or
gi0/1.
Step 3 Follow each interface command with the interface configuration commands your particular interface
requires. The commands 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 10-19.
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-range | macro
macro_name}
Enter interface range configuration mode by entering the range of
interfaces (VLANs or physical ports) to be configured.
• 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 10-10.
• Each comma-separated port-range must consist of the same port
type. You do not need to enter spaces before or after the comma.
• When you define a range, the space between the first port and the
hyphen is required.
Step 3
You can now use the normal configuration commands to apply the
configuration parameters to all interfaces in the range.
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.
