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 configuration of the Eth-Trunk interface is correct.

When using the display eth-trunk command, note that:

If no optional parameter is specified, the configurations of all Eth-Trunk interfaces are displayed.
If trunk-id is specified only, the configuration of a specified Eth-Trunk interface is displayed.
If trunk-id and interface interface-type interface-number are specified, the status of a specified member interface of a specified Eth-Trunk interface is displayed.
If trunk-id is specified and verbose is configured, the detailed configuration of a specified Eth-Trunk interface is displayed, including the statistics about interface traffic.

Prerequisites

The interface specified in this command must be an existing one.

Precautions

If there is a great deal of statistics about traffic on Eth-Trunk interfaces, you are recommended to specify trunk-id or interface interface-type interface-number to filter output information.

Unselected: indicates that the member interface is an inactive interface and forwards no traffic. 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 and LACP negotiation fails. If Status of all Eth-Trunk member interfaces is Unselected, it indicates that no member interface is selected in the Eth-Trunk interface in static LACP mode.
PortType	Type 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 LACP packets. 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 LACP packets. 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.

Flow statistic	Statistics about interface traffic
Last 300 seconds input rate Last 300 seconds output rate	Indicates the rates at which bytes and packets are sent and received by the interface in the last 300 seconds. The rates are re-calculated in bytes/300s and packets/300s each time the display eth-trunk command is run.
