Cuda 12000 IP Access Switch CLI Reference Guide
interface 181
interface
Use this command to enter interface configuration mode for a specific interface:
■ Ethernet
■ Cable
■ POS
■ Bridge-Group
■ Loopback
Mode
Any.
Syntax
interface {<chassis>/<slot>/<interface> | loopback}
Arguments
{<chassis>/<slot>/<interface> |
loopback}
Specifies one of the following values:
■ <chassis>/<slot>/<interface> – Specifies the combination of
chassis number, slot number, and interface number (port
number) that identifies the Ethernet, cable, POS, or
bridge-group interface you want to configure. The chassis
number can range from 1 to 128, though currently it can
only be 1. The slot number can range from 1 to 12. The
range of interface numbers depends on the number of
ports on the card.
■ loopback – Specifies the loopback interface, to enter
loopback mode. You can then manage this interface as you
would any other IP interface.
Note that this loopback interface differs from the standard
IP loopback interface (127.0.0.1). One of the uses of this
loopback interface is for opening in-band connections (such
as telnet sessions) to the Cuda 12000. Users can specify the
IP address of the loopback interface to open connections,
thereby eliminating the need to specify the IP address of a
physical interface (such as a CMTS interface).
