Usage Guidelines

Usage Scenario

After configuring an Eth-Trunk on a device, you can run the display eth-trunk command to check whether the Eth-Trunk configuration is correct.

When using the display eth-trunk command, pay attention to the following points:

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

Prerequisites

The Eth-Trunk has been correctly configured. If no Eth-Trunk is configured, when you run this command, the system displays an error message.

Precautions

If there are traffic statistics about many Eth-Trunks, you are advised to specify trunk-id or interface interface-type interface-number to filter output information. Otherwise, the following problems may occur due to excessive output information:

The displayed information is repeatedly updated, and required information cannot be located.
The system does not respond because of long-time information traverse and search.

Hash arithmetic	Hash algorithm used for load balancing among member interfaces of the Eth-Trunk. The hash algorithm is configured by using the load-balance command. The S2720-EI, S5720I-SI, S5720-LI, S5720S-LI, S5720S-SI, S5720-SI, S5730S-EI, S5730-SI, S6720-LI, S6720S-LI, S6720S-SI, and S6720-SI use the src-dst-ip, source TCP or UDP port number, and destination TCP or UDP port number in the hash algorithm for load balancing regardless of whether you configure this parameter.
System Priority	System LACP priority. To configure the LACP system priority, run the lacp priority command.
System ID	System ID.
Least Active-linknumber	Minimum number of active member links in Up state. To configure the minimum number of active member links in Up state, run the least active-linknumber command.
Max Active-linknumber	Maximum number of active member links in Up state. To configure the maximum number of active member links in Up state, run the max active-linknumber command.
Max Bandwidth-affected-linknumber	Maximum number of connections that affect the Eth-Trunk bandwidth.
Operate status	Eth-Trunk status: UP DOWN
Number Of Up Port In Trunk	Number of member interfaces in Up state in the Eth-Trunk.
ActorPortName	Name of a member interface.
Status	Status of the local member interface in LACP mode: Selected: A member interface in Selected state is active. Unselect: A member interface in Unselected state is inactive. ForceFwd: A member interface can forward Layer 2 traffic. Status of the local member interface in manual load balancing mode: Up: indicates that the interface is properly started. Down: indicates that the interface is faulty.
PortType	Type of the local member interface.
PortPri	LACP priority of the member interface.
PortNo	Number of the member interface in LACP mode.
PortKey	Key value of the member interface in LACP mode.
PortState	Status variable of the member interface. The status variable is eight bits, such as 10111100. The descriptions of each bit are as follows: Bit 1: Whether the member interface is an Actor. This bit has a fixed value 1. Bit 2: Whether the member interface uses a long or short timeout interval to receive LACPDUs. 1: The member interface uses a short timeout interval. 0: The member interface uses a long timeout interval. By default, an Eth-Trunk member interface uses the long timeout interval (90s) to receive LACPDUs. To set the timeout interval, run the lacp timeout command. Bit 3: 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. Bit 4: 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. Bit 5: Whether the member interface can receive LACPDUs. 1: The member interface can receive LACPDUs. 0: The member interface cannot receive LACPDUs. Bit 6: Whether the member interface can send LACPDUs. 1: The member interface can send LACPDUs. 0: The member interface cannot send LACPDUs. Bit 7: Whether the LACPDUs contain default parameter values. 1: The LACPDUs contain default parameter values. 0: The LACPDUs do not contain default parameter values.
