display interface ethernet brief
Function
The display interface ethernet brief command displays brief information about all Ethernet interfaces.
Usage Guidelines
Usage Scenario
You can use the display interface ethernet brief command to view brief information about Ethernet interfaces, including the physical status, auto-negotiation mode, duplex mode, bandwidth, and average inbound and outbound bandwidth usages within the last period of time. This information helps you locate and rectify faults.
Precautions
To clear statistics on an interface, run the reset counters interface command.
Example

Description |
|---|---|
Interface |
Type and number of an interface. All interfaces are displayed in alphabetical order. Information about the following interfaces can be displayed:
|
PHY |
Physical status of an interface:
|
Auto-Neg |
Whether auto-negotiation is enabled on an interface:
To configure the auto-negotiation mode for an interface, run the negotiation auto command. |
Duplex |
Duplex mode of an interface:
|
Bandwidth |
Bandwidth on the interface. |
InUti |
Average inbound bandwidth usage within the last 5 minutes. Average inbound bandwidth usage = Average inbound rate within the last 5 minutes/Interface bandwidth When the average bandwidth usage is smaller than 0.01% and larger than 0, the value 0.01% is displayed. When the interface bandwidth becomes smaller, for example, the bandwidth is changed using the speed command, or when an Eth-Trunk member interface becomes Down or is removed from the Eth-Trunk, the bandwidth usage may be displayed as 100% because the communication traffic is not adjusted in time. |
OutUti |
Average outbound bandwidth usage within the last 5 minutes. Average outbound bandwidth usage = Average outbound rate within the last 5 minutes/Interface bandwidth When the average bandwidth usage is smaller than 0.01% and larger than 0, the value 0.01% is displayed. When the interface bandwidth becomes smaller, for example, the bandwidth is changed using the speed command, or when an Eth-Trunk member interface becomes Down or is removed from the Eth-Trunk, the bandwidth usage may be displayed as 100% because the communication traffic is not adjusted in time. |
Trunk |
Number of the Eth-Trunk to which an interface is added. |
