A single word	`cat`	Topics that contain the word "cat". You will also find its grammatical variations, such as "cats".
A phrase. You can specify that the search results contain a specific phrase.	`"cat food"` (quotation marks)	Topics that contain the literal phrase "cat food" and all its grammatical variations. Without the quotation marks, the query is equivalent to specifying an OR operator, which finds topics with one of the individual words instead of the phrase.

Either word in a topic	`OR` `or` `\|` (pipe)	`cat OR dog` `cat \| dog`
Topics that do not contain a specific word or phrase	`NOT` `not` `!` (exclamation point)	`NOT cat` `! dog`

Monitor with the NNM iSPI for IP Multicast

The Network Node Manager iSPI for IP Multicast Software(NNM iSPI for IP Multicast) enables you to monitor the health of your multicast network.

IP multicast is a technology that efficiently sends data to a group of receivers in a single transmission to save network bandwidth. It is ideal for applications where the source transmits a large set of data to many destinations at one time.

The NNM iSPI for IP Multicast works in conjunction with NNMi to gather information about your multicast network. The NNM iSPI for IP Multicast monitors the multicast flows passing through the multicast-enabled nodes and Protocol Independent Multicast (PIM) interfaces.

Examples of the applications using an IP Multicast network:

Webcasts or audiocasts
Distance learning or video conferencing
Inventory, pricing, or stock data delivered to many destinations simultaneously

These applications need sufficient bandwidth or prioritization to prevent duplicate, dropped, or out-of-sequence packets. This requires the monitoring and management of the multicast traffic.

The NNM iSPI for IP Multicast, in conjunction with NNMi, enables you to perform the following tasks:

Discover and monitor the IP multicast routing topology in your network management environment.
Monitor the health of multicast-enabled nodes, PIM interfaces, and neighbors.
Monitor the flows against the expected flow topology.
View the list of receivers of a particular multicast flow.
Troubleshoot the network by using the IP multicast map views such as Forwarding Trees, Reverse Paths, Neighbor Views, and Snapshots.
Monitor the IP multicast Inventories from the Global Network Manager and Regional Manager.
Monitoring the incidents based on IP multicast activity to enable rapid identification of faults on the network.
Troubleshoot the IP Multicast-VPN network by integrating with the Network Node Manager iSPI for MPLS Software.
Generate the IP multicast reports using the NNM iSPI Performance for Metrics.
Monitor the IP multicast traffic flow rate available in the map views.

The traffic flow rate is available only if you deploy the Network Node Manager iSPI Performance for Metrics Software.
