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.
