**Table 1** Description of the **display interface ethernet brief** command output
Item	Description
Interface	Indicates the name and number of an interface. All interfaces are displayed in the lexicographic order. The interface can be: Ethernet Gigabit Ethernet
PHY	Indicates the physical status of the interface. The physical status can be: up: indicates that the interface runs normally. down: indicates that the physical layer of the interface fails. down: refers to Administratively Down, indicating that the administrator runs the shutdown* command on the interface. ^down: refers to standby, indicating that the interface is a standby interface. (l): refers to loopback, indicating that the interface is enabled with the loopback function. (b): refers to BFD down, indicating that the physical layer of the interface is in the BFD Down state.
Auto-Neg	Indicates whether auto-negotiation is enabled on the interface. The value can be: enable: indicates that the interface is enabled with auto-negotiation. disable: indicates that the interface is disabled with auto-negotiation.
Duplex	Indicates the duplex mode of the interface. The value can be: full: indicates that the interface is in the full-duplex mode.
Bandwidth	Indicates the bandwidth of the interface. The value can be: 10 Mbit/s or 100 Mbit/s for FE interfaces. 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s for GE interfaces.
InUti	Indicates the average bandwidth usage of the interface in the receiving direction within the latest five minutes. Average bandwidth usage of the interface in the receiving direction within the latest five minutes = Average traffic rate of the interface in the receiving direction within the latest five minutes/interface bandwidth When the average bandwidth usage of the interface in the receiving direction is smaller than 0.01% and the traffic is available, the value is displayed as 0.01%. When interface bandwidth becomes smaller, for example, when you use the speed command to adjust the interface bandwidth of an Ethernet interface, or a member interface of an Eth-Trunk interface goes Down or is unbound from the Eth-Trunk interface, bandwidth usage may be 100% because the communication traffic is not adjusted in a timely manner.
OutUti	Indicates the average bandwidth usage of the interface in the sending direction within the latest five minutes. Average bandwidth usage of the interface in the sending direction within the latest five minutes = Average traffic rate of the interface in the sending direction within the latest five minutes/interface bandwidth When the average bandwidth usage of the interface in the sending direction is smaller than 0.01% and the traffic is available, the value is displayed as 0.01%. When interface bandwidth becomes smaller, for example, when you use the speed command to adjust the interface bandwidth of an Ethernet interface, or a member interface of an Eth-Trunk interface goes Down or is unbound from the Eth-Trunk interface, bandwidth usage may be 100% because the communication traffic is not adjusted in a timely manner.
Trunk	Indicates the ID of the Eth-Trunk interface.
