Use the display interface null command to display information about the null interface. Because Null 0
interface is the only null interface on a device, this command displays information about Null 0 interface,
even if you do not specify the 0 parameter:
If you do not specify the null parameter, this command displays information about all interfaces on
the device.
If you specify the null parameter, this command displays information about interface Null 0 with or
without the 0 parameter, because the device supports only one interface Null 0.
