Bulk Configuration
Bulk configuration allows you to determine if interfaces are present for physical interfaces or configured for logical
interfaces.
Interface Range
An interface range is a set of interfaces to which other commands may be applied and may be created if there is at least
one valid interface within the range.
Bulk configuration excludes from configuration any non-existing interfaces from an interface range. A default VLAN may
be configured only if the interface range being configured consists of only VLAN ports.
The interface range command allows you to create an interface range allowing other commands to be applied to
that range of interfaces.
The interface range prompt offers the interface (with slot and port information) for valid interfaces. The maximum size of
an interface range prompt is 32. If the prompt size exceeds this maximum, it displays (...) at the end of the output.
NOTE: Non-existing interfaces are excluded from the interface range prompt. In the following example, Tengigabit
3/0 and VLAN 1000 do not exist.
NOTE: When creating an interface range, interfaces appear in the order they were entered and are not sorted.
The show range command is available under Interface Range mode. This command allows you to display all
interfaces that have been validated under the interface range context.
The show configuration command is also available under Interface Range mode. This command allows you to
display the running configuration only for interfaces that are part of interface range.
Bulk Configuration Examples
Use the interface range command for bulk configuration.
• Create a Single-Range
• Create a Multiple-Range
• Exclude Duplicate Entries
• Exclude a Smaller Port Range
• Overlap Port Ranges
• Commas
• Add Ranges
Create a Single-Range
The following is an example of a single range.
Example of the interface range Command (Single Range)
FTOS(config)# interface range gigabitethernet 0/1 - 23
FTOS(config-if-range-gi-0/1-23)# no shutdown
FTOS(config-if-range-gi-0/1-23)#
Create a Multiple-Range
The following is an example of multiple range.
