Usage Guidelines

Usage Scenario

The display interface brief command displays brief information about interfaces, including the physical status, link layer protocol status, inbound and outbound bandwidth usage within a certain period, and numbers of sent and received error packets. This information helps locate faults on interfaces.

Precautions

To clear statistics on an interface, run the reset counters interface command.

Description

Interface

Type and number of an interface.

In V200R008C50 and later versions, if (v) is displayed behind an interface number, the interface is a virtual interface.

PHY

Physical status of an interface:
  • up: indicates that the interface is working properly.
  • down: indicates that the physical layer of the interface fails.
  • *down: Administratively Down, indicating that the administrator has run the shutdown command on the interface.
  • ^down: indicates that the interface is a backup interface.
  • (l): indicates that the loopback function is enabled on the interface.
  • (s): indicates that the spoofing function is enabled on the interface.
  • (b): indicates that the link layer of the interface is in BFD Down state.
  • (e): indicates that the link layer of the interface is in EFM Down state.

Protocol

Link layer protocol status of the interface:
  • up: indicates that the interface is working properly.
  • down: indicates that the link layer protocol of the interface fails.
  • (s): indicates that the spoofing function is enabled on the interface.
  • (b): indicates that the link layer of the interface is in BFD Down state.
  • (e): indicates that the link layer of the interface is in EFM Down state.
  • (d): indicates that the protocol module of the interface is suppressed.
  • --: indicates that the link layer protocol status is not obtained.

InUti

Average inbound bandwidth usage of an interface within the last 300 seconds.

Average inbound bandwidth usage within the last 300 seconds = Average inbound traffic rate within the last 300 seconds/Interface bandwidth

When the average bandwidth usage is smaller than 0.01% and greater than 0, the value 0.01% is displayed. When the interface bandwidth becomes lower, the bandwidth usage may be displayed as 100% because the traffic volume is not adjusted in time. "--" indicates that an interface does not support the display of bandwidth usage.

OutUti

Average outbound bandwidth usage within the last 300 seconds.

Average outbound bandwidth usage within the last 300 seconds = Average outbound traffic rate within the last 300 seconds/Interface bandwidth

When the average bandwidth usage is smaller than 0.01% and greater than 0, the value 0.01% is displayed. When the interface bandwidth becomes lower, the bandwidth usage may be displayed as 100% because the traffic volume is not adjusted in time. "--" indicates that an interface does not support the display of bandwidth usage.

inErrors

Number of error packets received by an interface. The value becomes 0 when you run the reset counters interface command in the user view or when the number of received packets reaches the maximum value 0xFFFFFFFF.

outErrors

Number of error packets sent by an interface. The value becomes 0 when you run the reset counters interface command in the user view or when the number of sent packets reaches the maximum value 0xFFFFFFFF.
