VLAN Range
Restrictions for VLAN Range
The VLAN range feature has the following restrictions:
•
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.
Configuration Task for VLAN Range
To configure the VLAN range feature, perform the following required configuration task:
•
Configuring a Range of VLAN Subinterfaces, page 6-16
Configuring a Range of VLAN Subinterfaces
To configure a range of VLAN subinterfaces, enter the following commands beginning in global
configuration mode:
Command
Purpose
Step 1
Router(config)#
interface range
{{
ethernet
|
fastethernet
|
gigabitethernet
|
atm
}
slot
/
interface
.
subinterface
-
{
ethernet |
fastethernet | gigabitethernet | atm
}
slot
/
interface
.
subinterface
}
Selects the range of subinterfaces to be configured. If you
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.
