On the equipment navigation tree, expand NE→Logical Groups.

Right-click on LAGs and choose Create LAG. The Create LAG wizard opens.

Configure general properties

Configure the required parameters.

If you are creating a LAG for HSMDA, the Port Type parameter must be set to HSMDA. The Encapsulation Type must be either Dot1Q or QinQ. Setting Mode to network creates a network LAG, and setting it to access creates an access LAG.

If you are creating a LAG containing ports on an XMDA card on a 7705 SAR-18, the Encapsulation Type parameter must be either Dot1 Q or Null and the Mode must be set to Access.

The Weighted parameter is configurable only if the Per-Link Hashing parameter is enabled. The Auto Rebalance parameter is only configurable only if the Weighted parameter is enabled.

Consider the following when you configure the Enable DEI parameter on a hybrid LAG.

• When the Enable DEI parameter is selected, the Enable DEI parameter for the ports in the LAG must also be selected. See To configure Ethernet ports .

• Network policies assigned to the ports in the LAG must be configured to use DEI as the profile. The Default FC Profile parameter and the Profile parameter on the Ingress Dot1p tab must be set to the DEI option. See To configure a 7210 and 1830 network policy .

If you are configuring Ethernet ports for MWA 1+0 on a 7705 SAR-8 or 7705 SAR-18:

1. Set the Mode parameter to Network and the Encapsulation Type parameter to Dot1Q.

2. Set the MWA port Auto-negotiation parameter to Limited.

3. Create an MWA 1+0 link and add the port to the link.

4. Add the MWA 1+0 port to the LAG.

You can configure up to four MW links per LAG group, with a mix of MW and non-MW links with the same port speed settings. The LAG interface must be configured on the LAG group ID, not on the MW link. 1+1 is not supported, the redundancy is for L2 LAG only.

If you are configuring a LAG on a 7210 SAS NE that supports split horizon groups, you can select an SHG in the Split Horizon Group panel. See To create a 7210 SAS SHG for information about creating a 7210 SAS SHG.

Note: A LAG cannot be added to or deleted from an SHG if it has a SAP configured on it.

A LAG cannot belong to more than one SHG; you must remove all SHGs from the LAG before you can add the LAG to a different SHG.

Configure LAG parameters

Click Next. The Configure LAG Parameters step displays.

Configure the required parameters.

You must set the Port Threshold parameter to 0 when the Standby Signalling parameter is set to Power Off in Step 12 .

Perform one of the following:

1. If you set the Mode parameter in Step 3 to Access or Hybrid, go to Step 9 .

2. If you set the Mode parameter in Step 3 to Network, or if you did not configure the Mode parameter, go to Step 11 .

Configure access parameters

Click Next. The Configure Access Parameters step displays.

Configure the required parameters.

If you are creating a LAG for HSMDA, the QoS Adaptation parameter must be set to Link, otherwise the LAG will not be created.

Configure LACP parameters

Click Next. The Configure LACP form opens.

Configure the required parameters.

The LACP Mode, LACP Transmit Interval, Actor Administration Key, LACP System ID, and LACP System Priority parameters are configurable when the LACP Enabled parameter is enabled.

When the Standby Signalling parameter is set to Power Off, you must set the Active Sub-Group Selection Criteria parameter to Best Port.

Configure LAG members

Click Next. The Configure LAG Members step displays.

Click Create. The Only Show Compatible Ports wizard opens.

Configure the Show Only Compatible Ports and Class parameters.

Click Next. The Select Ports step displays.

Choose compatible ports to construct the LAG:

1. Choose one or more ports. The maximum number of ports you can add to a LAG is 64. The number or ports you can choose depends on the NE type; see the NE documentation for more information.

   Note:

   If there are no compatible ports to choose from and you want to edit some of the existing ports to be compatible, disable the Show Only Compatible Ports parameter in Step 15 .

   For ports to appear as compatible ports, ensure no SAPs or services are configured on them.

   You must use the same load balance algorithm for the ports associated with the LAG.

   The dot1x configuration modification is allowed only on the primary member port. These changes will be propagated to other member ports. Any new port added to LAG must have the same dot1x configuration as primary port.

   All ports added to a LAG must have the Enable DEI parameter set to the same configuration.

   Add subports of the same type, otherwise a validation error appears.

   For HSMDAv2 ports in a LAG, you must set the Auto-negotiate parameter to False or Limited. See To configure Ethernet ports for more information on configuring Ethernet ports.

   If you are creating a LAG containing ports on an XMDA card in the 7705 SAR-18, then the following conditions apply to the ports:

   • The Encapsulation Type must be set to either Dot1Q or Null.

   • The Mode parameter must be set to Access.

   • The Auto-negotiate parameter must be set to False or Limited.

2. Click Next. The Specify the Member Properties step displays.

3. Configure the parameters.

4. If required, perform Step 42 of To configure Ethernet ports to add Egress Secondary Shapers to a port member of an HSMDA LAG.

   The add/delete/modify functions for Egress Secondary Shapers apply only to the primary port.

   There can be a total of 64 egress secondary shapers per MDA, including the default shaper.

   The Egress Secondary Shapers on the primary port of the LAG are propagated to each non-primary port member of the LAG, with a maximum 8 ports per LAG. These propagated shapers cannot be deleted.

   For adding any new port to the LAG, the user must configure each Egress Secondary Shaper as per the primary port, otherwise the addition of the port is blocked.

   When adding a port member to a LAG, the primary port and each selected port (maximum 8 ports) secondary shapers must have the same name and rate.

   Ports with Egress Secondary Shapers cannot be added to a configured LAG which do not match the Egress Secondary Shapers of the primary port.

   Shapers are not removed from the port when the port is removed from a LAG.

   The SAP reference to the Egress Secondary Shapers within a LAG is supported. Only the primary port of the SAP on the LAG is used to determine the list of Egress Secondary Shapers for the SAP.

   Note:

   When port members are removed from the LAG, care must be taken to ensure that the last port member is not removed if the LAG is referenced to a SAP. Shapers must exist on a LAG to be referenced on a SAP. See Chapter 70, Service management and QoS to Chapter 85, Composite service management for more information.
