Configuring LACP on a port

Configure LACP on a port to enable LACP.

You must use the LACP keys to determine which ports are eligible for link aggregation. The LACP keys are defined by the ports after you configure the multilink trunk. You can aggregate the ports key that match the MLT key into that multilink trunk.

The minimum LACP configuration is as follows:

Assign a given key to a set of ports.
Assign the same key to an MLT with no members. The ports will automatically become MLT members.

Keys do not have to match between two LACP peers.

Procedure

In the Device Physical View tab, select a port.
In the navigation tree, expand the following folders: Configuration > Edit > Port.
Click General.
Click the LACP tab.
To enable LACP on the port, select the AdminEnable check box.
To assign an LACP key, configure the ActorAdminKey field.
Configure the remaining parameters as required.
Click Apply.

LACP field descriptions

Use the data in the following table to use the LACP tab.

All the parameters beginning with Partner are for debug purposes only. If you configure these commands locally and there is a mismatch with what is learned from the partner, there will be trace or log message.


Name	Description
AdminEnable	Enables LACP status for the port. The default value is false.
OperEnable	Displays the operational status of LACP for the port. The default value is false.
FastPeriodicTime	Specifies the number of milliseconds between periodic transmissions using short timeouts for all LACP enabled ports. The range is 200–20000. The default value is 1000.
FastPeriodicTimeOper	Displays the operating value of the fast periodic timer on the port. The default value is 1000.
SlowPeriodicTime	Specifies the number of milliseconds between periodic transmissions using long timeouts for all LACP enabled ports. The range is 10000–30000. The default value is 30000.
SlowPeriodicTimeOper	Displays the operating value of the slow periodic timer on the port. The default value is 30000.
AggrWaitTime	Specifies the number of milliseconds to delay aggregation to allow multiple links to aggregate simultaneously. The range is 200–2000. The default value is 2000.
AggrWaitTimeOper	Displays the operating value of the aggregate wait timer on the port. The default value is 2000.
TimeoutScale	Assigns the value used to calculate timeout time from the periodic time. Set this value to all LACP enabled ports. The range is 2–10. The default value is 3.
TimeoutScaleOper	Displays the operating value of the timeout scale on the port. The default value is 3.
ActorSystemPriority	Specifies the two octet read-write value indicating the priority value associated with the actor system ID. The range is 0–65535. The default value is 32768.
ActorSystemID	Displays the six octet read-write MAC address value used as a unique identifier for the system that contains this aggregator. From the perspective of the link aggregation mechanisms, only a single combination of actor system ID and system priority are considered, and no distinction is made between the values of these parameters for an aggregator and the ports that are associated with it; that is, the protocol is described in terms of the operation of aggregation within a single system. However, the managed objects provided for the aggregator and the port both allow management of these parameters. The result of this is to permit a single piece of equipment to be configured by management to contain more than one system from the point of view of the operation of link aggregation. This can be of particular use in the configuration of equipment that has limited aggregation capability.
ActorAdminKey	Specifies the current read-write administrative value of the key for the aggregator, which is a 16-bit value in the range of 0–65535. The administrative key value can differ from the operational key value. This key needs to match the LAG key.
ActorOperKey	Displays the current read-only operational value of the key for the aggregator. The operational key value can differ from the administrative key value. The meaning of particular key values is of local significance.
SelectedAggID	Displays the identifier value of the aggregator that this aggregation port has currently selected. Zero indicates that the aggregation port has not selected an aggregator, either because it is in the process of detaching from an aggregator or because there is no suitable aggregator available for it to select. This value is read-only.
AttachedAggID	Displays the identifier value of the aggregator to which this aggregation port is currently attached. Zero indicates that the aggregation port is not currently attached to an aggregator. This value is read-only.
ActorPort	Displays the port number locally assigned to the aggregation port. The port number is communicated in LACPDUs as the Actor_Port. This value is read-only.
ActorPortPriority	Specifies the priority value assigned to this aggregation port. This 16-bit value is read-write in the range of 0–65535. The default value is 32768.
ActorAdminState	Specifies a string of eight bits, corresponding to the administrative values as transmitted by the actor in LACPDUs, by selecting check boxes. The values are the first bit corresponds to bit 0 of Actor_State (LACP_Activity) (the default value) the second bit corresponds to bit 1 (LACP_Timeout) the third bit corresponds to bit 2 (Aggregation) the fourth bit corresponds to bit 3 (Synchronization) the fifth bit corresponds to bit 4 (Collecting) the sixth bit corresponds to bit 5 (Distributing) the seventh bit corresponds to bit 6 (Defaulted) the eighth bit corresponds to bit 7 (Expired) These values allow administrative control over the values of LACP_Activity, LACP_Timeout, and aggregation. This attribute value is read-write.
ActorOperState	Displays a string of eight bits, corresponding to the current operational values of Actor_State as transmitted by the actor in LACPDUs. This attribute value is read-only. The default value is lacpActive.
PartnerAdminSystemPriority	Specifies the current administrative value of the port number for the protocol partner. It is a 16-bit read-write value in the range of 0–65535. The assigned value is used, along with the value of PartnerAdminSystemPriority, PartnerAdminSystemID, PartnerAdminKey, and PartnerAdminPortPriority, to achieve manually configured aggregation. The default value is 0.
PartnerOperSystemPriority	Displays a two octet read-only value indicating the operational value of priority associated with the partner system ID. The value of this attribute can contain the manually configured value carried in PartnerAdminSystemPriority if there is no protocol partner. The default value is 0.
PartnerAdminSystemID	Specifies a six octet read-write MAC address value that represents the administrative value of the aggregation port protocol partners system ID. The assigned value is used with the values of PartnerAdminSystemPriority, PartnerAdminKey, PartnerAdminPort, and PartnerAdminPortPriority to achieve manually configured aggregation. The default value is 00:00:00:00:00:00.
PartnerOperSystemID	Displays a six octet read-only MAC address value that indicates representing the current value of the aggregation port protocol partner system ID. A value of zero indicates that there is no known protocol partner. The value of this attribute can contain the manually configured value carried in PartnerAdminSystemID if there is no protocol partner. The default value is 00:00:00:00:00:00.
PartnerAdminKey	Specifies the current administrative value of the key for the protocol partner. It is a 16–bit read-write value in the range of 0–65535.
