To modify a LAG

Before you begin

This procedure applies to 7210 SAS, 7250 IXR, 7450 ESS, 7705 SAR, 7750 SR, and 7950 XRS NEs. See To configure OmniSwitch dynamic LAG members for information about configuring a LAG on an OmniSwitch. See the NSP NFM-P Microwave Radio User Guide for information about configuring a LAG on a Wavence NE.

Steps
 

On the equipment navigation tree, expand Network→NE→Logical Groups→LAGs→LAG n.


Right-click on the LAG n object and choose Properties. The LAG (Edit) form opens.


Configure general parameters
 

Configure the required parameters.

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

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


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.


If you are configuring a LAG on a 7850 VSG, you can select a port profile and an operational group in the OperGroup and ServiceProfle panel.


Configure other LAG parameters
 

Click on the Link Aggregation Group tab and configure the required parameters.

You must set the Port Threshold parameter to zero when the Standby Signalling parameter is set to Power Off in Step 9 .


Click on the States tab and configure the Administrative State parameter.


If you are configuring a LAG in Access or Hybrid mode, click on the Access tab and configure the required parameters.

If you are configuring a LAG for HSMDA, the QoS Adaptation parameter must be set to Link.


Click on the LACP tab and configure the required parameters.

The LACP Mode, LACP Transmit Interval, and Actor Administration Key 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

Click on the LAG Members tab.

You can also add LAG members by right-clicking on an existing LAG object and choosing Create LAG Members from the contextual menu.

To add LAG members, perform Step 14 to Step 18 of To create a LAG .


11 

Perform one of the following steps:

  1. If the LAG that you are configuring is in Network mode, the Network Interfaces tab is displayed. Click Create. The Create Network Interface form opens. See To create an L3 network interface on a routing instance for information on creating a network interface. Otherwise go to Step 17 .

  2. If the LAG that you are configuring is in access mode or hybrid mode with dot1q or QinQ encapsulation, or in network mode with dot1q encapsulation, the MEPs tab is displayed. Go to Step 12 .


12 

Add a facility MEP to the LAG:

Note: Only one facility MEP can be configured on a LAG.

  1. Click on the MEPs tab and click Create. The MEP (Create) form opens.

  2. Select a global MEG.

  3. Configure the required parameters.

    Note:

    You cannot enable the collection of LMM statistics on a facility MEP if a service MEP is already configured to collect the LMM statistics information.

    The CCM Padding Packet Size (Bytes) parameter cannot be configured when the CCM interval parameter is set to 10 ms or 100 ms.

    To enable fault propagation on a LAG facility MEP, the Facility Fault Notify parameter must be enabled.

  4. If the MD for the MEP has a Name Type of None, the Y.1731 Tests tab is configurable; click on the Y.1731 Tests tab and configure the required parameters.

    The Eth Test Pattern parameter is configurable when the Eth Test Enabled parameter is enabled.

  5. Save your changes and close the form.


13 

To add a tunnel facility MEP to the LAG, perform the following steps.

The LAG that you are configuring must be in Access mode or Hybrid mode and must have an encapsulation type of QinQ.

  1. Click on the MEPs tab.

  2. Click Create. The MEP (Create) form opens.

  3. Select a global MEG.

  4. Configure the required parameters.

    Note:

    The CCM Padding Packet Size (Bytes) parameter cannot be configured when the CCM interval parameter is set to 10 ms or 100 ms.

    To enable the fault propagation on a tunnel facility MEP, Facility Fault Notify must be enabled.

    To link the tunnel facility status to the SAP, Facility VLAN ID must match the outer encapsulation value of the SAP.

    To accept the fault notification from a facility MEP on the site where the SAP is located and on the SAP, Tunnel Fault Management must be set to Accept.

  5. If the MD for the MEP has a Name Type of None the Y.1731 Tests tab is configurable; click on the Y.1731 Tests tab and configure the required parameters.

    The Eth Test Pattern parameter is configurable when the Eth Test Enabled parameter is enabled.

  6. Save your changes and close the form.


14 

Configure Ethernet-CFM redundancy on a facility MEP.

You must enable Ethernet CFM redundancy globally on a device before it can function on child objects such as LAGs. See Chapter 12, Device object configuration for information about device object configuration.

The tunnel MEP must be part of an MC-LAG with Ethernet CFM redundancy configured.

  1. Click on the MEPs tab.

  2. Choose the facility MEP for which you need to configure Ethernet-CFM redundancy and click Properties. The MEP (Edit) form opens.

  3. On the Facility MEPS panel, enable the Create Redundant MEP parameter.

  4. Click OK to confirm. A redundant tunnel MEP with the same ID and Operational MAC address is created on the peer LAG. The redundant MEP has the same state as the MC-LAG in which that MEP resides.


15 

Configure BFD parameters:

  1. Select the IPv4 or IPv6 entry and click Properties. The BFD Configuration on LAG form appears.

  2. Configure the required parameters.

  3. Save your changes and close the form.


16 

Configure Operational Group parameters:

  1. Select the Oper Group and Monitor Oper Group value.

  2. Save your changes.


17 

Save your changes and close the form.
