Description
Use display interface null 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 keyword.
If you do not specify the null keyword, this command displays information about all interfaces on
•
the device.
If you specify the null keyword, this command displays information about interface Null 0 with or
•
without the 0 keyword, because the device supports only one interface Null 0.
