5 Managing OpenFlow alerts and
troubleshooting service flows
SDNM is used to manage OpenFlow alerts and troubleshoot SDN service flows.
Managing OpenFlow alerts
When a controller is added to SDNM, SDNM registers an alert listener with the controller so that the
controller can send the generated OpenFlow alerts to SDNM.
SDNM enables is used to view, query, acknowledge, recover, and delete the following OpenFlow alerts:
• OpenFlow alerts generated by controllers.
• OpenFlow alerts generated by SDNM.
Accessing the alert list page
1. Click the Service tab.
2. From the navigation tree, select VAN SDN Manager > OF Monitor > Alerts.
The alert list displays all alerts in SDNM.
