Usage Guidelines

Usage Scenario

After configuring an Eth-Trunk interface on a device, you can run the display eth-trunk command to check whether the configurations of the Eth-Trunk interface are correct.

Prerequisites

The interface specified in this command must be an existing one. This ensures that valid entries are displayed after you execute the 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 eth-trunk** command output
Item	Description
PortName	Eth-Trunk member interface name.
Slave/Master	Master/backup status of an Eth-Trunk member interface: M: indicates a master interface. S: indicates a backup interface.
LAG ID	ID of the Eth-Trunk interface.
Preempt Delay	Preemption delay of an Eth-Trunk interface in static LACP mode. You can configure and change the preemption delay of an Eth-Trunk interface in static LACP mode using the lacp preempt delay command.
Hash arithmetic	Load balancing mode: According to flow: per-flow load balancing. According to packet all: per-packet load balancing.
System Priority	LACP priority of the system. After Eth-Trunk interfaces in static LACP mode are added to an E-Trunk, you can configure or modify the system priority using the lacp e-trunk priority command.
System ID	System ID. After Eth-Trunk interfaces in static LACP mode are added to an E-Trunk, you can configure or modify the system ID using the lacp system-id command.
Least active-linknumber	Minimum number of active member links. If the number of Eth-Trunk member interfaces that are in the Up state is less than the Least Active-linknumber value, the Eth-Trunk interface goes Down. You can change the Least Active-linknumber value by running the least active-linknumber (Eth-Trunk interface view) command.
Max Active-linknumber	Maximum number of active member links. You can configure and change the maximum number of active member links using the max active-linknumber command.
Max bandwidth-affected-linknumber	Maximum number of member interfaces that affect the actual bandwidth of the Layer 2 Eth-Trunk interface.
Operate status	Status of the Eth-Trunk interface: UP: indicates that the Eth-Trunk interface is in the Up state and can forward traffic. DOWN: indicates that the Eth-Trunk interface is in the Down state and cannot forward traffic.
Number Of Up Ports In Trunk	Number of Up member interfaces in the Eth-Trunk interface.
Timeout Period	Timeout period during which an Eth-Trunk interface in static LACP mode fails to receive LACPDUs. You can configure or modify the timeout period using the lacp timeout command.
ActorPortName	Name of a member interface.
Status	Status of local member interfaces: Selected: A member interface in the Selected state is active. Unselected: A member interface in the Unselected state is inactive. Up: The member interface is brought up. Down: The member interface is shut down. Offline: The member interface is offline. If an Eth-Trunk interface works in static LACP mode and Status is Unselected, no interface is selected as the Eth-Trunk interface's member interface. Consequently, LACP negotiation fails.
PortType	Type of local member interface.
PortPri	LACP priority of the member interface in an Eth-Trunk interface in static LACP mode. You can configure and change the LACP priority of the member interface using the lacp priority command.
PortNo	LACP number of the member interface in an Eth-Trunk interface in static LACP mode.
PortKey	LACP key of the member interface in an Eth-Trunk interface in static LACP mode.
PortState	Status variable of the member interface in an Eth-Trunk interface in static LACP mode. The status variable is an 8-bit binary number, such as 10111100. The descriptions of each bit are as follows: First bit: whether the member interface is an Actor. This bit has a fixed value 1. Second bit: whether the member interface uses a long or short timeout period to receive LACPDUs. 1: The member interface uses a short timeout period. 0: The member interface uses a long timeout period. By default, an Eth-Trunk member interface uses the long timeout (90 seconds) period to receive LACPDUs. The value can be changed using the lacp timeout command. Third bit: whether the system allows the member interface to be aggregated. 1: the system allows the member interface to be aggregated. 0: the system does not allow the member interface to be aggregated. Fourth bit: whether the member interface is added to the link aggregation group (LAG). 1: The member interface is added to the LAG. 0: The member interface is not added to the LAG. Fifth bit: whether the member interface can receive packets. 1: The member interface can receive packets. 0: The member interface cannot receive packets. Sixth bit: whether the member interface can send packets. 1: The member interface can send packets. 0: The member interface cannot send packets. Seventh bit: whether the packets have default contents. 1: The packets have default contents. 0: The packets do not have default contents. Eighth bit: whether the receive state machine of the Actor is in Expired state. 1: It is in Expired state. 0: It is not in Expired state.
Weight	Weight of the member interface in an Eth-Trunk interface.
Flow statistic	Eth-Trunk traffic statistics.
Interface	Interface name and number.
Last 300 seconds input rate Last 300 seconds output rate	Rates at which bits and packets are sent and received by the interface in the last 300 seconds. Each time this command is run, the rates at which bits and packets are sent and received by the interface within the last 300s are re-collected. The rates at which bits and packets are sent and received by the interface within the last 300s are displayed. The rates at which bits and packets are sent and received by the interface within the last 300s are calculated respectively. The interval at which traffic statistics are collected can be changed using the set flow-stat interval command.
Role	Member interface role of the Eth-Trunk interface in static LACP mode: MASTER: master role. SLAVE: backup role. NONE: no role set. You can set or change the role of a member interface using the lacp port-role command.
Local	Configuration of the local Eth-Trunk interface.
WorkingMode	Operation mode of the Eth-Trunk interface: NORMAL: manual load balancing mode. STATIC: static LACP mode. You can configure and change the operation mode of an Eth-Trunk interface using the mode command.
Partner	Information about remote Eth-Trunk member interfaces.
Input	Total number of packets and bytes received by an interface. packets: total number of packets. The total number of packets received by an Eth-Trunk interface is the total number of packets received by all Eth-Trunk member interfaces. bytes: total number of bytes. The total number of bytes received by an Eth-Trunk interface is the total number of bytes received by all Eth-Trunk member interfaces. drops: number of discarded packets.
Output	Total number of packets and bytes sent by an interface. packets: total number of packets. The total number of packets sent by an Eth-Trunk interface is the total number of packets sent by all Eth-Trunk member interfaces. bytes: total number of bytes. The total number of bytes sent by an Eth-Trunk interface is the total number of bytes sent by all Eth-Trunk member interfaces. drops: number of discarded packets.
Remote	Interface's system ID synchronized with that on the peer device through an E-Trunk connection.
Act	Number of activated links.
Inact	Number of deactivated links.
Cfgd	Number of configured links.
BW	Link bandwidth.
WorkingState	Master/backup status of an Eth-Trunk interface: Master: indicates a master interface. Slave: indicates a backup interface.
preempt delay time	Preemption delay.
ports	Port number.
PortKeyMode	LACP member interface's PortKey generation mode: Auto: The system automatically generates a value. Manual: The configuration is generated manually.
