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.

Description

*down:

Reason why an interface is physically Down. Administratively down indicates that the administrator has run the shutdown command on the interface.

^down: standby

Indicates that the interface is a backup interface.

(l): loopback

Indicates that the loopback function is enabled on the interface.

(s): spoofing

Indicates that the spoofing function is enabled on the interface.

(E): E-Trunk down

Indicates that the Eth-Trunk is Down because of the protocol negotiation on the E-Trunk.

The number of interface that is UP/DOWN in Physical is

Up or Down state of a physical link and number of interfaces in different states.

The number of interface that is UP/DOWN in Protocol is

Up or Down state of the protocol and number of interfaces in different states.

Interface

Interface type and number.

IP Address/Mask

IP address and subnet 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.
