Information
When creating an interface range, interfaces appear in the order they are entered; they are not sorted.
The command verifies that interfaces are present (physical) or configured (logical). Important things to
remember:
• Bulk configuration is created if at least one interface is valid.
• Non-existing interfaces are excluded from the bulk configuration with a warning message.
• The interface range prompt includes interface types with slot/port information for valid interfaces.
The prompt allows for a maximum of 32 characters. If the bulk configuration exceeds 32
characters, it is represented by an ellipsis ( ... ).
• When the interface range prompt has multiple port ranges, the smaller port range is excluded from
the prompt.
• If overlapping port ranges are specified, the port range is extended to the smallest start port and the
biggest end port.

Only VLAN and port-channel interfaces created using the interface vlan and vlan tagged commands
can be used in the interface range command.
Use the show running-config command to display the VLAN and port-channel interfaces. VLAN or
port-channel interfaces that are not displayed in the show running-config command cannot be used
with the bulk configuration feature of the interface range command. You cannot create virtual
interfaces (VLAN, Port-channel) using the interface range command.
Version 8.3.17.0 Supported on M I/O Aggregator
FTOS(conf)#interface range tengig 2/0 - 1 , tengig 10/0 , tengig 3/0
, fa 0/0
% Warning: Non-existing ports (not configured) are ignored by
interface-range
FTOS(conf)#interface range tengig 2/0 - 23 , tengig 2/1 - 10
FTOS(conf-if-range-tengig-2/0-23#
Note: If a range has VLAN, physical, and port-channel interfaces, only commands related to
physical interfaces can be bulk configured. To configure commands specific to VLAN or
port-channel, only those respective interfaces should be configured in a particular range.
FTOS(conf)#interface range tengig 2/1 - 11 , tengig 2/1 - 23
