Parameters

Parameter	Description	Value
interface-type	Displays brief IP configurations of a specified type of interface. If no interface type is specified, the system displays IP configurations of and statistics on all interfaces.	-
interface-number	Displays brief IP configurations of a specified interface. ifNum and ifType define an interface. If an interface type is specified but no interface number is specified, statistics on and IP configurations of all the interfaces of the specified type are displayed.	-
slot slot-number	Displays the IP configuration and statistics of interfaces on the specified slot. If the slot number is not specified, brief IP configurations of the interfaces on all interface boards and main control boards are displayed. In VS mode, this parameter is supported only by the admin VS.	-
card card-number	Displays the IP configuration and statistics of interfaces on the specified slot. If the slot number is not specified, brief IP configurations of the interfaces on all interface boards and main control boards are displayed. In VS mode, this parameter is supported only by the admin VS.	-
ip-configured	Displays the IP configuration of interfaces assigned IP addresses.	-

Usage Guidelines

Usage Scenario

To view the physical status, protocol status, and IP address of an interface, run the display ip interface brief command. The obtained information about interface status and configurations helps you diagnose interface faults.

Precautions

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

IP configurations of all interfaces
IP configurations of interfaces of the specified type, specified interfaces, interfaces in the specified slot, or interfaces on the specified board in the slot
IP configurations of interfaces assigned IP addresses
This command, however, cannot be used to display the IP configurations of member interfaces of a Trunk.
If an interface is used for services exclude IP services, no information about the interface is displayed with this command.

Example

The actual command output varies according to the device. The command output here is only an example.

**Table 1** Description of the **display ip interface brief** command output
Item	Description
(l): loopback	The loopback function is configured on the interface.
(s): spoofing	The spoofing feature of the link protocol status of the interface. That is, the link protocol status of the interface is always Up. This is the build-in attribute of an interface. When this interface is assigned an IP address, (s) is still displayed.
(d): Dampening Suppressed	Protocol of the interface is suppressed.
(E): E-Trunk down	The Eth-Trunk interface goes Down due to E-Trunk protocol negotiation.
The number of interface that is UP/DOWN in Physical is	Status (Up or Down) of a physical link and number of interfaces in different states.
The number of interface that is UP/DOWN in Protocol is	Status (Up or Down) of a protocol and number of interfaces in different states.
Physical	Physical status of an interface: Up: The interface is running normally. Down: The interface becomes faulty. *down: An administrator runs the shutdown command on the interface. !down: The forwarding information base (FIB) module is in the overload suspension state. In this case, the link protocol status of the interface is Down.
Protocol	Link protocol status of the interface: Up: The link protocol status of the interface is normal. Down: The link protocol status of the interface is abnormal, or the interface is not assigned an IP address.
Interface	Interface type and number. Bandwidth identifier displayed in the brackets after a interface: Actual bandwidth of the interface. For example, the name of a 10 Gbit/s main interface or sub-interface is tagged with the 10G bandwidth identifier.For a main interface or sub-interface whose bandwidth is limited by a license, the bandwidth identifier is displayed after the interface name.For a main interface or sub-interface with adaptive bandwidth, the bandwidth identifier is displayed after the interface name.
IP Address/Mask	IP address and subnet mask of a Layer 3 interface.
VPN	Status of a virtual private network (VPN) configured on the interface: -: No VPN is configured. l3vpn: Specifies the VPN configured for the interface is an L3VPN.
*down	Reason that interface is physically Down. Administratively DOWN: The network administrator runs the shutdown command on the interface.
(td): transceiver unmatch down	The interface does not match the optical module.
!down	The interface goes Down because the number of route prefixes in the FIB exceeds the upper limit.
^down	The interface is a backup interface.
