Chapter 9 Configuring Interface Characteristics
Using Interface Configuration Mode
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:
When using the interface range global configuration command, note these guidelines:
• Valid entries for port-range:
–
vlan vlan-ID - vlan-ID, where VLAN ID is from 1 to 4094
–
fastethernet switch/module/{first port} - {last port}, where switch is 1 and module is 0
–
gigabitethernet switch/module/{first port} - {last port}, where switch is 1 and module is 0 for
the standard SFP module ports and 1 for the ES SFP module ports
–
port-channel port-channel-number - port-channel-number, where port-channel-number is
from 1 to 12
Note When you use the interface range command with port channels, the first and last port
channel number must be active port channels.
• You must add a space between the first interface number and the hyphen when using the
interface range command. For example, the command interface range fastethernet 1/0/1 - 5 is a
valid range; the command interface range fastethernet 1/0/1-5 is not a valid range.
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 9-9.
• 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
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.
