Command History
Usage Guidelines You can use the passive-interface range command on the following interfaces: FastEthernet,
GigabitEthernet, VLAN, Loopback, Port-channel, 10-GigabitEthernet, and Tunnel. When you use the
passive-interface range command on a VLAN interface, the interface should be the existing VLAN
SVIs. To display the VLAN SVIs, enter the show running config command. The VLANs that are not
displayed cannot be used in the passive-interface range command.
The values that are entered with the passive-interface range command are applied to all the existing
VLAN SVIs.
Before you can use a macro, you must define a range using the define interface-range command.
All configuration changes that are made to a port range through the passive-interface range command
are retained in the running-configuration as individual passive-interface commands.
You can enter the range in two ways:
• Specifying up to five interface ranges
• Specifying a previously defined macro
You can either specify the interfaces or the name of an interface-range macro. An interface range must
consist of the same interface type, and the interfaces within a range cannot span across the modules.
default (Optional) All interfaces become passive.
interface-type Specifies the interface type.
interface-number Specifies the interface number.
range Specifies the range of subinterfaces being configured; see the “Usage
Guidelines” section.
