How do I resize LAGs?

This procedure can be used to increase or decrease the capacity of IP links that are carried over LAGs with traffic running through an optical network.

 
1 

Import and configure the lag-resize intent by performing the following steps:

  1. Download the nsp-cdrc-lag-resize intent file for the current release from Nokia Electronic Delivery service.

  2. Open Network Intents.

  3. Click Import, select the nsp-cdrc-lag-resize-rel.zip intent, and click Open. When imported, the intent is named icm-logical-lag-access.

  4. Open Device Management, Configuration Intent Types.

  5. Click png1.png IMPORT, select icm-logical-lag-access, and click Import.

  6. Wait for the intent to initialize and the Status to display “Successful”.

2 

Create the configuration template for the intent by performing the following steps:

  1. Open Device Management, Configuration Templates.

  2. Click png1.png TEMPLATE.

  3. In the form that opens, perform the following steps:

    • Under Basic Info, set Template Name to “lag-resize”. Setting this value is mandatory.

    • Click png1.png INTENT TYPE, select icm-logical-lag-access and click ADD.

    • Click RELEASE. The configuration template is created.

3 

Deploy the intent by performing the following steps:

  1. Open Device Management, Configuration Deployments.

  2. Click png1.png DEPLOYMENT and choose Logical from the drop-down list. The Deploy Logical Configuration form opens.

  3. Under Select Template, click png1.png TEMPLATE, select the lag-resize template that you created previously, and click ADD.

  4. Under Select Targets and Edit Selected Template, click png1.png TARGET select a single NE and click ADD. Only one NE can be selected.

  5. In Select Targets and Edit Selected Template, click VIEW/EDIT TEMPLATE CONFIG. The configuration form for lag-resize opens.

  6. Set only the following parameter values and click UPDATE:

    • Admin State - enabled

    • Max Ports - 64

    • Encap Type - null

    • Mode - trunk

  7. If the LAG already exists on the node, in Assign Identifier for Selected Template, set the LAG-NAME and LAG-ID parameters as configured on the node. If the LAG has not been created yet, go to step Step 4.

  8. Click DEPLOY.

  9. Wait until the Deployment Status displays "Deployed Aligned".

  10. Repeat from sub-step 4 to deploy the intent for the second node. If you are creating a protection group, then performing these steps on a single node is sufficient.

If the LAG has not yet been created on the node, perform the following steps. Skip to step Step 5 if the LAG already exists.

  1. Open Device Management, Configuration Deployments.

  2. Choose the lag-resize template, click More png13.png, Associate to network.

    The Associate Template form opens with the template already selected.

  3. Under Select Targets and Edit Selected Template, click png1.png TARGET select a single NE and click ADD. Only one NE can be selected.

  4. In Assign Identifier for Selected Template, set the LAG-NAME and LAG-ID parameters.

  5. Click Associate to apply the configuration. Validate that under the Configuration Deployments drop-down an entry is created for the selected node with Deployment Status as Deployed Aligned.

  6. Repeat this step and sub-steps to deploy the intent for the second node. If you are creating a protection group, then performing these steps on a single node is sufficient.

To expand a LAG, perform the following:

  1. Open IP/Optical Coordination, IP-Optical Correlation. A list of IP links is displayed.

    IP links that are part of a LAG will be identified as 'Elastic' in the Elastic column.

  2. Select an 'Elastic' IP link in the list and click Info png18.png. The Info panel opens.

  3. Click More png13.png for a Link Layer Interconnect and choose Expand LAG from the contextual menu. The Expand LAG form opens.

  4. Click png1.pngADD, then select an endpoint to deploy as Link Layer Interconnects.

  5. Click DEPLOY. The Expand LAG form closes and the IP link displays “EXPAND IN PROGRESS” in the Elastic column.

  6. Click More png13.png and choose View Progress from the contextual menu to show the status of the expansion.

    NOTE: If no operation is ongoing, clicking View Progress will show the results of the most recently-completed operation.

    When successfully completed, the IP link will again be identified as 'Elastic' in the Elastic column.

  7. Once the deployment is complete, the following occurs:

    1. a new service is displayed in WS-NOC

    2. a new Optical Service is displayed in the IP/Optical Coordination Optical Service view

    3. an additional LLI is displayed in the IP/Optical Coordination IP-Optical Correlation, Info png18.png view for the relevant IP link

6 

If the LAG expansion fails, viewing the Operational Status in the Info png18.png for the link displays the failure cause.

7 

To contract a LAG, perform the following steps:

  1. Open IP/Optical Coordination, IP-Optical Correlation. A list of IP links is displayed.

  2. Select an 'Elastic' IP link in the list and click Info png18.png

  3. Click Contract png4.png inline with any Link Layer Interconnect. A form opens.

  4. Click Delete to confirm.
