Command
Step 1

The commands you enter in interface range configuration mode (the mode you enter after issuing
the interface range command) are executed as you enter them. The commands are not batched
together for execution after you exit interface range mode. If you exit interface range configuration
mode while the commands are being executed, some commands might not be executed on some
interfaces in the range. Wait until the command prompt reappears before exiting interface range
configuration mode.
All configuration changes made to a range of subinterfaces are saved to NVRAM, but the range itself
does not get saved to NVRAM. To create and save a range, enter the define interface-range global
configuration command.
Cisco IOS software does not support the no interface range command. To delete a range of
subinterfaces, you must delete the individual subinterfaces.

specify subinterfaces that have not been previously created,
the interface range command creates the subinterfaces.
Enters interface range configuration mode.
Note
The spaces around the dash are required. For
example, the command interface range
fastethernet 1 - 5 is valid; the command interface
range fastethernet 1-5 is not valid.
