display ip interface

Function

The display ip interface command displays the IP configuration and statistics on interfaces. The statistics include the number of packets and bytes received and sent by interfaces, number of multicast packets sent and received by interfaces, and number of broadcast packets received, sent, forwarded, and discarded by interfaces.

The display ip interface brief command displays brief information about interface IP addresses, including the IP address, subnet mask, physical status, link-layer protocol status, and number of interfaces in different states.

Format

display ip interface [ interface-type interface-number ]

display ip interface brief [ interface-type [ interface-number ] | slot slot-id [ card card-number ] ]

display ip interface brief [ interface-type ] &<1-8>

Parameters

Parameter	Description	Value
interface-type interface-number	Specifies the type and number of an interface. If no interface is specified, IP configuration and statistics about all interfaces are displayed.	-
brief	Displays brief information, including the IP address, subnet mask, physical status, link-layer protocol status, and number of interfaces in different states.	-
slot slot-id	Displays the IP configuration and statistics of interfaces on the specified slot. If the slot number is not specified, brief information related to the IP addresses of the interfaces on all interface boards and main control boards is displayed.	-

Usage Guidelines

You can run the display ip interface brief command to view the following information:

IP configurations of all interfaces
IP configurations of interfaces of the specified type and a specified interface
IP configurations of interfaces that have IP addresses

This command, however, cannot display the IP configurations of Layer 2 interfaces or Eth-Trunk member interfaces.

You can run the display interface description command to view the interface description.
You can run the display interface command to view detailed information about the running status and statistics on the interface.

**Table 1** Description of the **display ip interface** command output
Item	Description
Vlanif15 current state	Physical status of the interface: UP: indicates that the interface is physically Up. DOWN: indicates that the interface is physically Down. Administratively down: indicates that the administrator has run the shutdown (interface view) command on the interface.

**Table 2** Description of the **display ip interface brief** command output
Item	Description
*down:	Reason why an interface is physically Down. Administratively down indicates that the administrator has run the shutdown command on the interface.
^down	^down: indicates that the interface is a backup interface.
(l): loopback	The letter "l" refers to loopback.
(s): spoofing	The letter "s" refers to spoofing.
(E): E-Trunk down	Indicates that the Eth-Trunk is Down because of the protocol negotiation on the E-Trunk.
Interface	Interface type and number.
IP Address/Mask	IP address and mask of an interface.
Physical	Physical status of an interface: Up: indicates that the interface is physically Up. (l) indicates that the loopback function is configured on the interface. Down: indicates that the interface becomes faulty. down: indicates that the administrator has run the shutdown (interface view)* command on the interface. (l) indicates that the loopback function is configured on the interface. !down: indicates that the FIB module is suspended. In this case, the link protocol status of the interface is Down.
Protocol	Link protocol status of the interface: Up: indicates that the link protocol of the interface is running properly. (s) indicates that the link protocol status of the interface is Up when this interface is created and has no IP address configured. This is an inherent attribute of an interface. When this interface is configured with an IP address, (s) is still displayed. Down: indicates that the link protocol of the interface fails or no IP address is configured on the interface. (l) indicates that the loopback function is configured on the interface.
