Buttons

Button	Description
Delete	To release the occupied resources, you can delete the redundant or idle LAGs. NOTE: You are user with Operator Group authority or higher. NOTICE: This operation interrupts services on the LAGs. The LAG occupied by the MC LAG cannot be deleted.
Query	When a network fault occurs, you can analyze the fault causes and locate the faulty equipment by querying the working status of a LAG. NOTE: If a LAG is not queried before, the member port status is Unknown. If a port is the actually working port and services are forwarded at the port, the port status is Working. If a port is the standby port and no service is forwarded at the port, the port status is Unworking. Applies to the LAGs in the static aggregation mode. The LAG must be configured on the peer equipment.

NOTE:

You are user with Operator Group authority or higher.

NOTICE:

This operation interrupts services on the LAGs.

The LAG occupied by the MC LAG cannot be deleted.

Query

When a network fault occurs, you can analyze the fault causes and locate the faulty equipment by querying the working status of a LAG.

NOTE:

If a LAG is not queried before, the member port status is Unknown.

If a port is the actually working port and services are forwarded at the port, the port status is Working.

If a port is the standby port and no service is forwarded at the port, the port status is Unworking.

Applies to the LAGs in the static aggregation mode.

The LAG must be configured on the peer equipment.

Parameters

Field	Value	Description
LAG No.	Example: 1	Set the number of the LAG. You can also select the automatic allocation.
LAG Name	Example: LAG_1	Set the name of the LAG.
LAG Type	Static, Manual	Manual: Indicates that an LAG does not run the LACP protocol. The system selects one or more ports in a manual LAG to carry services according to the status (a port can carry services only when it is up), rate (a port with a higher rate is selected with precedence), and the duplex mode (a port can carry services only when it is in full-duplex mode) of the port. Static: Indicates that an LAG runs the LACP protocol and the protocol packets are communicated between the two ends of an LAG. For a static LAG, the protocol state machine determines which ports in the LAG are used to carry services. NOTE: The LAG types at the two ends of an LAG must be the same. A static LAG is highly reliable and therefore is recommended. However, a manual LAG needs to be configured when the PTN equipment is interconnected with equipment that does not support the LACP protocol. For a manual LAG, Ethernet port OAM (802.3ah) is recommended for detecting link status to ensure that the two ends of the LAG perform coordinated switching actions (namely, selects the same link to carry services) in case of a unidirectional fiber cut.
Revertive Mode	Revertive, Non-Revertive	Select the revertive mode.
Load Sharing	Non-Sharing, Sharing	Sharing: All member links in the LAG bear traffic, and share the load. The load is shared to increase the bandwidth of the links. When the member links change or some member links fail, the system automatically re-allocate the traffic. Non-Sharing: Only one member link in the LAG bears traffic. The other member link is in the standby state. In this way, a mechanism similar to hot backup is available. When the active link in the LAG fail, the system automatically selects the other link for protection against the link failure. Hence, the interruption of the upper-layer protocols is avoided.
Load Sharing Hash Algorithm	Automatic, Source MAC, Destination MAC, Source and Destination MAC, Source IP, Destination IP, Source and Destination IP, Source Port Number, Destination Port Number, Source and Destination Port Numbers, MPLS Label	Set Load Sharing Hash Algorithm properly to ensure that the service flows in compliance with the algorithm are transported over the same link. In this way, the received data packets are in the correct frame sequence. This parameter can be set only when Load Sharing is set to Sharing.
System Priority	0 to 65535	The LAG priority and system MAC address indicate the system ID, which is used for negotiation with the opposite equipment. The equipment with a higher system priority has the priority for selection.
WTR Time(min)	0 to 30	Specifies the wait-to-restore time of the switching. Indicates the waiting time before switching services from the standby link to the active link. You can set this parameter to avoid frequent switchover between the active and standby links due to the instability of the active link.
Switch LAG upon Air Interface SD	Enabled, Disabled	Specifies whether the LAG switchover is triggered when a bit error occurs. If this parameter is set to Enabled, the LAG switchover is triggered when a bit error occurs. If this parameter is set to Disabled, the LAG switchover is not triggered when a bit error occurs. Only IF interface supports this parameter.
Main Port	Example: Slot-Board Name-Port(Port No.)	Select the main port of the LAG.
Main Port Status	In Service, Out of Service, /	Display the working state of the main port.
Standby Port	Example: Slot-Board Name-Port(Port No.)	Select the standby port of the LAG.
Standby Port Status	In Service, Out of Service, /	Display the working state of the standby port.
Switching Protocol	Null, 3ah	Null: indicates that a manual LAG does not use the switch protocol. 3ah: indicates that a manual LAG uses the extended 802.3ah protocol as the switch protocol. When the local equipment is connected to the equipment that supports the extended 802.3ah protocol, it is recommended that the local equipment use the extended 802.3ah protocol as the switching protocol to ensure that the two ends take the same switching actions (that is, the two ends select the same link to carry services). Specifies the switching protocol for a manual LAG. NOTE: This parameter can be set and queried only when LAG Type is set to Manual.
Switching Mode	Active, Passive	In active mode, the local LAG determines the status (active or standby) of the link that the member ports in the local LAG belong to based on the status of the member ports and transmits the link status information to the peer equipment by using the extended 802.3ah packets. In passive mode, the local LAG receives the status information (active or standby) of the link that the member ports in the peer LAG belong to and selects a link to carry services according to the received link status information. NOTE: This parameter can be set and queried only when LAG Type is set to Manual. This parameter value takes effect only when Switching Mode is set to 3ah.
Link Detection Protocol	Null, 3ah, -	Null: indicates that a manual LAG does not use the link detection protocol. 3ah: indicates that a manual LAG uses the 802.3ah protocol as the link detection protocol. Specifies the link detection protocol for a member link in a manual LAG.
LAG Min. Active Links	1 to 255	LAG Min. Active Links works with simple LPT and determines the minimum number of active links in a LAG. If the number of active links in the LAG is smaller than this value, the U2000 Web LCTconsiders the LAG faulty and triggers LPT. The default value is 1, indicating that the U2000 Web LCTconsiders a LAG faulty when all links in the LAG are faulty.
Packet Receive Timeout Period	Long period, Short period	In some scenarios where two devices are interconnected, the peer device may not support the short period. Packet loss occurs if the timeout periods of the two devices are different. In this situation, you need to set Packet Receive Timeout Period to long period. When configuring LAG protection between two nonadjacent NEs (traversed by the third-party network), you are advised to set this parameter to Short Period. Packet Receive Timeout Period can be set only when LAG Type is set to Static. Short period: packet send period: 1s, packet receive timeout period: 3s Long period: packet send period: 30s, packet receive timeout period: 90s NOTE: If a port does not receive packets from its peer in the long period, alarms are automatically reported and the port keeps waiting after the time is reset.
