Monitor Your Network with IP Multicast Forms

The NNM iSPI for IP Multicast provides forms that help you easily view all details associated with the managed object such as multicast-enabled node, interface, or multicast flow (S, G). In addition, the Analysis Pane of the NNM iSPI for IP Multicast shows information about the multicast-enabled node, interface or flow. This topic includes the following sections:

Use the NNM iSPI for IP Multicast forms to complete the following tasks:

  • Determine the health of the multicast objects. Check the status and incident tabs.
  • Access a multicast map view.
  • Navigate to the tabs associated with the multicast node, PIM interface, and multicast flow (S, G).
  • See the information about the selected multicast-enabled node, interface, or flow using the Analysis pane.

The following forms are available from the IP Multicast workspace:

Form Name Description
IP Multicast Node Provides details about the selected Multicast node. For more information, see IP Multicast Node Form.
IP Multicast Interface Provides details about the selected PIM interface. For more information, see IP Multicast Interface Form.

  • Deviation in flow rate beyond the specified threshold
  • Addition of nodes to this flow
  • Deletion of nodes from this flow

The NNM iSPI for IP Multicast also generates incidents when the creation of baseline and last snapshot fail.

You can check the incidents related to IP Multicast Flows from the IP Multicast Flow forms or NNMi Incidents Browsing workspace. If you do not have access to the starting router of a flow or the starting router belongs to another security group, you cannot see the incidents related to that flow.

The following IP Multicast incidents related to IP Multicast Flows appear on the console:

Incidents Related to IP Multicast Flows
IP Multicast Incident Name Description Severity of the Incident
MulticastFlowMonitorFailure Appears when any of the four incidents namely MulticastFlowTopoChange, MulticastFlowTopoExtended, MulticastFlowRateDeviationOutOfRange, or MulticastFlowRPChange occurs. This is a parent incident that includes the listed correlated children incidents. Critical
MulticastFlowTopoChange Appears when there is a change in the topology due to the deletion of nodes. Some nodes in the baseline snapshot no longer receive multicast traffic for this Flow. Critical
MulticastFlowTopoExtended Appears when there is an addition of nodes. Some additional nodes, which were not in the baseline snapshot, have started receiving multicast traffic for this flow. Warning
MulticastFlowRateDeviationOutOfRange

Appears when there is a flow rate deviation more than the configured threshold value. The default deviation rate is 20%, which can be changed for each flow.

Critical
MulticastFlowRPChange Appears when there is a change in the RP in the multicast flow. Critical
MulticastFlowBaseliningFailed Appears when baseline creation fails. The flows cannot be compared without a baseline. Warning
MulticastFlowSnapshotFailed Appears when the last snapshot creation fails. Warning

The NNM iSPI for IP Multicast generates an incident for a particular type of fault or failure only once for a specific flow. If the failures of the same type occur again, NNM iSPI for IP Multicast does not generate the incident for the subsequent failures of the same type.

For example, the NNM iSPI for IP Multicast generates an incident namely MulticastFlowTopoChange, when a particular node does not receive the multicast data. If two more nodes do not receive the data over a period of time before you close this incident, the NNM iSPI for IP Multicast does not generate additional incidents for the next two nodes as MulticastFlowTopoChange incident already exists for the particular flow.
