interface range
interface range
Use the interface range global configuration command to enter interface range configuration mode and
to execute a command on multiple ports at the same time. Use the no form of this command to remove
an interface range.
interface range {port-range | macro name}
no interface range {port-range | macro name}
Syntax Description
Defaults This command has no default setting.
Command Modes Global configuration
Command History
Usage Guidelines From the interface range configuration mode, all interface parameters that you enter are applied to all
interfaces within the range.
For VLANs, you can use the interface range command only on existing VLAN interfaces. To display
VLAN interfaces, enter the show running-config privileged EXEC command. VLANs not displayed
cannot be used in the interface range command. The commands that you enter under the interface
range command are applied to all existing VLAN interfaces in the range.
All configuration changes made to an interface range are saved to NVRAM, but the interface range itself
is not saved to NVRAM.
You can enter the interface range in two ways:
• Specifying up to five interface ranges
• Specifying a previously defined interface-range macro
You can define up to five interface ranges with a single command, with each range separated by a
comma (,).
All interfaces in a range must be the same type; that is, all Fast Ethernet ports, all Gigabit Ethernet ports,
all EtherChannel ports, all Long-Reach Ethernet (LRE) ports, or all VLANs.
These are the valid values for port-range type and interface:
• vlan vlan-id, where vlan-id is from 1 to4094
• port-channel port-channel-number, where port-channel-number is from 1 to 6
port-range Port range. For a list of valid values for port-range, see the “Usage Guidelines”
section.
macro name Specify the name of a macro.
