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 9-8.
• 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.
