Chapter 1 CLI Command Reference
interface range
You cannot use the interface range command to create switch virtual interfaces (SVIs) in that particular
range. You can use the interface range command only to configure existing VLAN SVIs within the
range. To display VLAN SVIs, enter the show running-config command. VLANs not displayed cannot
be used in the interface range command.
The commands entered under the interface range command are applied to all existing VLAN SVIs
within the range.
You can enter the command interface range create vlan x - y to create all VLANs in the specified range
that do not already exist. If you are using discontiguous VLANs, you can use the interface range vlan
command to configure multiple SVIs without creating unneeded SVIs and wasting interface descriptor
blocks (IDBs).
After specifying a VLAN range, you can continue using the interface range command to specify
another interface (ATM, Fast Ethernet, Gigabit Ethernet, loopback, port-channel, or tunnel).
Note VLANs 4093, 4094, and 4095 are reserved and cannot be configured by the user.
