9 Chapter 1: Overview Multicast Manager allows you to manage multicast traffic within your network environment. This includes the identification and monitoring of all multicast groups, sources, receivers and other critical sources like rendezvous point (RP) routers. Multicast Manager discovers and models Cisco and Juniper devices that support Multicast traffic. Once these devices are discovered, Multicast Manager provides several views which enable you to monitor the connectivity and performance of these Multicast elements. These views offer details relating to Multicast groups, sources, receivers, routers, and RPs and their relationships to each other. The information provided in the Multicast Manager views makes troubleshooting Multicast-related outages much more efficient. You can isolate a problem quickly because you can determine the group a receiver belongs to, the RP of the group, the source for the group, the routers and interfaces that a group uses, and the configuration and bandwidth limits of these interfaces. Based on this information, you can prioritize your troubleshooting efforts should multiple problems occur. If you purchase a multicast service or a data feed from an external service and you do not have access to the source to obtain its status, Multicast Manager provides you with the ability to create a proxy to the source or you can configure Multicast Manager to exclude the unmanageable source s status in group condition calculation. For more information on excluding the source s status in the group condition calculation, see Configuration Information on page 21. For more information on defining a proxy for an unmanageable (unreachable) source, see Define a Proxy for an Unmanageable Source on page 29. Overview 1

11 Chapter 2: Multicast Manager Interface This chapter describes the Multicast Manager interface. For additional information about OneClick, see the OneClick Console User Guide (5130). Access Multicast Manager In the OneClick console, you can access Multicast Manager from the Explorer tab of the Navigation panel. When you expand the Multicast Manager node, all of the Groups managed by Multicast Manager are listed. When you expand each Group, the Routers and Sources contained in the Multicast Group are listed. Multicast Manager Interface 3

12 Access Information About Your Multicast Network Access Information About Your Multicast Network Once the physical components of your Multicast network are modeled in SPECTRUM, you can use Multicast Manager to discover your Multicast devices. You can then navigate to or search for these Multicast elements in OneClick. The Contents panel and Component Detail panel provide configurations, alarms, events, and other information for a selected Multicast element. The following chapters describe how to configure Multicast Manager, discover your modeled Multicast elements, configure management of Multicast elements, and monitor your Multicast Network. For more information on modeling your network, see the Modeling Your IT Infrastructure Administrator Guide (5167). The following figure displays an example of information Multicast Manager provides to you. 4 Multicast Manager User Guide

13 Chapter 3: Multicast Manager Configuration This chapter describes Multicast Manager s Configuration options. This information is presented in the following sections: Access Multicast Manager Configuration Parameters on page 6 Configure Multicast Discovery on page 6 Management Configuration on page 8 Performance Analysis Configuration on page 9 Multicast Manager Configuration 5

14 Access Multicast Manager Configuration Parameters Access Multicast Manager Configuration Parameters The Multicast configuration parameters are available to all users with administrative privileges. To access these parameters: 1. Expand the desired landscape from the OneClick Explorer tab and select the Multicast Manager. 2. Select the Information tab in the Contents panel. 3. Expand the Configuration node to display the following options: Configure Multicast Discovery You can set the following parameters in the Multicast Discovery sub-view: Device Reconfiguration Discovery: This will run a Device Application Reconfiguration action. Discovery Polling Interval (sec): This interval determines how often (in seconds) Multicast Manager polls the attribute in the CiscoIPMRoute MIB during a background discovery to determine if new Multicast Groups, Sources, or routers exist. 6 Multicast Manager User Guide

15 Configure Multicast Discovery Enable Background Discovery: When Enable Background Discovery is set to Yes, events are created when new Multicast Groups, Sources, or routers become active on the network. Events for new Groups and Sources are asserted on the Multicast Manager model. Events for new Multicast routes are asserted on the applicable device model. Note: Before you enable background discovery, run a manual discovery to ensure that you find and model the RP routers that will be associated with discovered groups. To determine if a new entity has become active, Multicast Manager polls an attribute in the Cisco IPMRoute MIB which counts the number of entries in the Multicast routing table. Background Create Group Models: When set to Yes, this attribute will create models for the new Multicast Groups, Sources, or routers discovered from a background discovery. Note: Enable Background Discovery must be set to Yes. Group Addresses Excluded: This attribute allows you to choose the groups to exclude from a background discovery. Model Sources as Pingables: Because of the IT infrastructure in your particular network environment, it may not be possible for you to model the device representing the Source of the Multicast traffic. In this case, when you run Multicast Discovery with the Model Sources as Pingables parameter set to Yes, Multicast Manager creates a model using the pingable model type for each Multicast Source that does not have a corresponding device model. Multicast manager automatically assigns a model name to this pingable model using the convention <IPAddress>_mcast. The models created by running Multicast Discovery are placed in the Multicast Pingables Generic Container in the landscape topology view. Note: By default Multicast Manager determines the default gateway for the Source model. A correct default gateway is necessary for calculating performance and view in the topology. For instructions on verifying the default gateway, see Configuration on page 26. Enable MSDP Discovery: When set to Yes, this attribute enables MSDP Discovery. For more information see Multicast Source Discovery Protocol on page 13. Create Groups without Source: Some Multicast groups are not managable because they initiate outside of your network. If there is no manageable source to the group, then the group stays in the Initial condition and no fault management information is computed. When Create Groups without Source is set to No, Multicast Manager ignores groups for which you are not responsible. This is set to Yes by default. Multicast Manager Configuration 7

16 Management Configuration Management Configuration You can set the following parameters in the Management Configuration view: Default Group Priority: This sets the priority value given to a Group when it is created. This value defines the relative importance of the Group and can be used by the network operator to prioritize troubleshooting resources when there are problems with multiple Groups. This value can be changed for a specific Group in the individual Group model s Manage a Multicast Group on page 20. Enable Port Polling: If this value is set to Yes, when Multicast Discovery is run, it enables port polling on all interfaces associated with Group models. This enables port status to contribute to the overall Group condition. The default value of this attribute is Yes. Topology Display Units: Use this attribute to select the units displayed in the Topology graph. You can choose % Throughput or Packets. Global Enable Multicast Path Change Detection: This attribute enables or disables Multicast Manager s ability to detect topology changes in the Multicast distribution tree. It does this by identifying changes in the device interface receiving Multicast traffic. By default, it is set to No. You can also enable or disable this feature on a Group model basis. For more information, see the individual Group model description in the section Performance Analysis Configuration on page 21. Total Groups (modeled/known): This attribute shows the number of Groups that are modeled and known by Multicast Manager. The number of Groups modeled is the number of Multicast Groups that have been discovered and are presently modeled by Multicast Manager. The number of Groups known reflects the number of Groups discovered by Multicast Manager via the discovery process, but that are not currently modeled; that is, they have been deleted. Group Count Threshold: The Group count threshold, which if exceeded, generates a critical alarm on the Multicast Manager model. Total Sources (modeled/known): This attribute shows the number of Sources that are modeled and known by Multicast Manager. The number of Sources modeled is the number of Multicast Sources that have been discovered and are presently modeled by Multicast Manager. The number of Sources known reflects the number of Sources discovered by Multicast Manager via the discovery process, but that are not currently modeled; that is, they have been deleted. Source Count Threshold: The Source count threshold, which if exceeded, generates a critical alarm on the Multicast Manager model. 8 Multicast Manager User Guide

17 Performance Analysis Configuration Performance Analysis Configuration You can set the following parameters in the Performance Analysis Configuration section: Device Performance Alarms: This parameter enables or disables the generation of Multicast performance based alarms on the device; these alarms are asserted in addition to those on the Multicast Group model. If enabled, alarms are produced on the device models in the Group causing the threshold violation. By default, this parameter is set to Disable. Performance Analysis: This attribute is used to enable or disable the entire Multicast Performance Monitoring system. By default, it is set to Enable. You can also enable or disable performance monitoring on a Group model basis. For more information on enabling or disabling performance monitoring for a Multicast Group, see Performance Analysis Configuration on page 21. Note: Performance Analysis must be enabled for performance information to be displayed in the Multicast Topology view. For more information about the Multicast Topology view, see View Multicast Topology Information on page 32. Collection Interval (sec): This parameter determines the interval at which the devices are sampled to obtain performance and IfIndex information. The default value is 300 seconds (5 minutes). Lowering the interval may have a negative impact on the overall SpectroSERVER performance. Multicast Manager Configuration 9

19 Chapter 4: Multicast Manager Discovery and Modeling This chapter describes how to discover and model your Multicast network environment. This information is presented in the following sections: Model Your Multicast Network on page 11 Multicast Discovery on page 12 Multicast Source Discovery Protocol on page 13 Delete Device Models on page 13 Model Your Multicast Network SPECTRUM discovers and models the physical network infrastructure using Discovery, manual modeling, or the Modeling Gateway. Before using the Multicast Discovery on page 12 functionality in Multicast Manager, you must first model the physical components of your network in SPECTRUM using one of these methods. See the Modeling Your IT Infrastructure Administrator Guide (5167) and the Modeling Gateway Toolkit Guide (5069) for instructions on using these mechanisms to model your network. Multicast Manager Discovery and Modeling 11

20 Multicast Discovery Multicast Discovery Once the physical network components have been discovered, network elements which implement the Multicast MIBs supported by Multicast Manager can be discovered and modeled. This discovery is based on the MIBs specified within Chapter 7: Device Support. These MIBs provide the information required to identify all the primary Multicast components. Multicast Manager models Multicast Groups, Sources, and Receivers. To do this, Multicast Manager uses Group, Source, and Receiver model types. Group models represent a domain-wide Multicast data stream. The Source and Receiver models represent the producer and consumer of information in a Multicast network. The RP represents the meeting point for sources and receivers in a Multicast network. Run Multicast Discovery You must log in with administrator privileges to run Multicast Discovery. To run a Multicast Discovery 1. Expand the desired landscape from the OneClick Explorer tab and select the Multicast Manager. Information and Configurations display in the Contents panel. 2. Select the Information tab in the Contents panel. Expand the Configuration node. Expand the Multicast Discovery node, as shown in the following figure. Multicast Discovery controls and configurations display. 3. Set the appropriate Discovery parameters as described in Configure Multicast Discovery on page 6. Click Run next to the Discovery Status field to begin Multicast Discovery. The Discovery Status field shows the status of the discovery process. 12 Multicast Manager User Guide

21 Multicast Source Discovery Protocol Multicast Source Discovery Protocol SPECTRUM supports the Multicast Source Discovery Protocol (MSDP). This means that when you create a device model using OneClick Discovery, AutoDiscovery, or manual modeling, SPECTRUM automatically discovers MSDP information on network devices that support the MSDP protocol. This information is used during the Multicast Discovery process to identify Multicast network elements only visible from your network domain via MSDP. If you have already created device models representing the physical components of your Multicast network with a SPECTRUM release prior to 7.1 SP2, you must use the Device Reconfiguration Discovery button to discover MSDP protocol support on your network. After the Device Reconfiguration Discovery finishes, rerun Multicast Discovery. Delete Device Models You can delete a Device model by selecting the Device and selecting Delete from the right-click menu. If a device model is deleted, any associated Multicast Group, Source, or Receiver model is also deleted. Multicast Manager Discovery and Modeling 13

29 Manage a Multicast Group Landscape: The SPECTRUM landscape to which the Group model belongs. Notes: Notes or comments about the group. To add a note, click Set. Type the appropriate information. When you have finished typing the note, click Save. If you do not want to save the note that you entered, click Cancel. Configuration Information The following attribute displays in the Configuration Information sub-view: Ignore initial/unmodeled sources in group condition: Enables you to choose (on a per-group basis) whether or not to include the status of the source model in the group condition calculation. If you purchase a Multicast service or a data feed from an external service, you may not have access to the source to obtain its status. You can use this option to exclude the source s status in the group condition calculation. If you do own and have access to the source of the multicast stream, you should include the source status in the group status configuration. Performance Analysis Configuration Performance analysis shows you important information about the flow of Multicast traffic on your network. In a properly functioning Multicast network, each point of the network (where Multicast is enabled for that Group) should experience the same traffic flow in packets per second or bytes per second. Any deviation from the traffic level as measured at the source could indicate one or more of the following scenarios: A change in Group membership. A change in routing where Multicast traffic is taking a different path due to load balancing, a redundant failover, or a change from Shared to Source mode. A change in the network s Multicast configuration where Multicast has been disabled on an interface or device. A change in interface status. Device or link instabilities. The following parameters, displayed in the Performance Analysis Configuration sub-view, enable you to configure how Multicast Manager analyzes the performance of the Group model selected. A graphical representation of source traffic is also available (see the Source Performance Information on page 28). Note: To access performance configuration parameters that apply across all Group models, see Performance Analysis Configuration on page 9. Managing the Multicast Network 21

30 Manage a Multicast Group Global Group Performance Analysis: This value indicates whether the entire Multicast Performance Monitoring system is enabled or disabled. It can be set in the Multicast Manager model s Performance Analysis Configuration. The value of this parameter must be set to enable for the Group Performance Analysis to function. For more information about Performance Analysis Configuration, see Performance Analysis Configuration on page 9. Group Performance Analysis: Set this value to enable to enable performance monitoring for each Group. This value must be enabled for performance information to be displayed in the Multicast Topology view. For more information on the Multicast Topology view, see View Multicast Topology Information on page 32. Percent Degradation Threshold: This parameter defines the percent variation allowed in the monitoring of Group performance. For example, if the source is measured at 100 pps, all other points in the network receiving this Group should be within this percent threshold (+/-). Otherwise, a threshold violation is noted for the Group on that device. The default value is 3 percent. Enable Multicast Path Change Collection: When this parameter is set to Yes, the Multicast Group looks for changes in the interface receiving Multicast traffic. If a change is detected, an event is generated on the offending device. This event gives information about the device that generated the event, the interface receiving the traffic, and the Group to which the device belongs. By default, this parameter is set to No. The following scenarios can cause a change in path to be detected: A router performs a routine load balancing operation and redirects the Multicast traffic to be routed around the network by a different path. This does not necessarily indicate a failure. A router along the path of the Multicast traffic goes down. In this case a topology change will occur and the device receiving the Multicast traffic will detect that the interface sending the information has changed. Enable Path Change Alarms: If this parameter is set to Yes, Multicast Manager generates a yellow (minor) alarm when a change in path is detected. For this parameter to operate correctly, Enable Multicast Path Change Collection must be set to Yes. Group Performance Alarms: Set this value to Enable if you want Multicast Manager to create an alarm in response to the violation of performance thresholds defined in the Minor, Major, and Critical Alarm Threshold parameters. Minor Alarm Threshold: This parameter sets the Minor Threshold Percent. This value determines the severity of threshold violations on a Group. For example, a Group may have 100 interfaces sampled in the network. If more than the Minor Alarm Threshold percentage and less than the Major Alarm Threshold percentage of those samples are in violation of the Performance Degradation Threshold, a Minor event (and an alarm if Group Performance Alarms is set to enable) is generated. 22 Multicast Manager User Guide

31 Manage a Multicast Group Major Alarm Threshold: This parameter sets the Major Threshold Percent. This value determines the severity of threshold violations on a Group. For example, a Group may have 100 interfaces sampled in the network. If more than the Major Alarm Threshold percentage and less than the Critical Alarm Threshold percentage of those samples are in violation of the Performance Degradation Threshold, a Major event (and an alarm if Group Performance Alarms is set to enable) is generated. Critical Alarm Threshold: This parameter sets the Critical Threshold Percent. This value determines the severity of threshold violations on a Group. For example, a Group may have 100 interfaces sampled in the network. If more than the Critical Alarm Threshold percentage of those samples are in violation of the Performance Degradation Threshold, a Critical event (and an alarm if Group Performance Alarms is set to enable) is generated.

Multicast Source Management Multicast Manager provides several informative views about your multicast sources as well as the ability to define a source proxy and default gateway. Source Management Information The Component Detail panel contains tabs that enable you to view additional information about a Source selected from the search results list in the Contents panel. The Information tab provides a number of views for the Source. If a Multicast Source is unmanageable, you can define a source proxy. For more information on defining a Multicast Source proxy, see Define a Proxy for an Unmanageable Source on page 29. Managing the Multicast Network 25

34 Multicast Source Management General Information The following information for the Multicast Source model is displayed in the General Information sub-view: Condition: The status of the Source model. Possible conditions are initial (blue), normal (green), minor alarm (yellow), major alarm (orange), contact lost (red), unknown (gray), and maintenance (brown). Source Address: The IP address of the Source. Model Class: The model class of the Source model. For more information on a model type s model class, see the Concepts Guide (0647). Creation Time: The creation date and time of the Source model. Security String: The SNPMP community string or password for the device. If you have the appropriate permissions, you can modify the security string. Click set, type the security string into the available field, and press Enter. Landscape: The SPECTRUM landscape to which the Source model belongs. Configuration The Configuration sub-view allows you to define a proxy to reach the selected source and reconfigure the Default Gateway. Default Gateway: The IP Address of the device SPECTRUM should poll to obtain base-line performance statistics for a Multicast Group. This value will generally be the IP address of the default gateway for the Multicast Source. By default Multicast Manager determines the default gateway. The default gateway must be correct to utilize the Multicast Performance and Topology views. Click Set to modify the IP address. Note: When the default gateway is set to the Virtual IP address of a Hot Standby Routing Protocol (HSRP) group, for Multicast Performance Analysis to work properly, it is necessary to configure the HSRP member routers to send HSRP related SNMP Traps to SPECTRUM. This enables SPECTRUM to continue obtaining Multicast performance statistics when the Active HSRP router changes. Proxy IP: The IP Address of the proxy for an unmanageable Multicast Source. This allows you to compute condition and gather performance data for an unmanageable source using the information from the closest ingress router to the unmanageable source. For more information about defining a proxy for an unmanageable source, see Define a Proxy for an Unmanageable Source on page 29. Source Device The following information is shown about the Source device for the Multicast Source model. Condition: The status of the device model that represents the Source. Possible conditions are initial (blue), normal (green), minor alarm (yellow), major alarm (orange), critical alarm (red), gray (unknown), and maintenance (brown). 26 Multicast Manager User Guide

35 Multicast Source Management Name: The model name of the model that represents the Source. Network Address: The network address of the Source device. Manufacturer: The manufacturer of the Source device. Model Class: The model class of the model that represents the Source. For more information on a model type s model class, see the Concepts Guide (0647). MAC Address: The MAC address of the Source device. Type: The model type of the model that represents the Source device. Landscape: The SPECTRUM landscape on which the Source device is modeled. Group List This view shows information on the Group model to which the Source model sends information. Condition: The status of the device model that represents the Source. Possible conditions are initial (blue), normal (green), minor alarm (yellow), major alarm (orange), critical alarm (red), gray (unknown), and maintenance (brown). Name: The model name of the model that represents the Group. Group Priority: The relative importance of the Group. It can be used to prioritize troubleshooting resources when there are problems with multiple Groups. The smaller the number the higher the level of priority. Administrators can set this value in the Group model s Manage a Multicast Group on page 20. Mode: The Multicast mode of the Group. The value can be either sparse or dense. Type: The model type of the model that represents the Group. Model Class: The model class of the model that represents the Group. For more information on a model type s model class, see the Concepts Guide (0647). Source Event Information You can access the Event view for a Source by selecting a Source model and then selecting the Events tab from the Component Detail view. This tab displays event information for events that occur on the Source model. Managing the Multicast Network 27

36 Multicast Source Management Source Performance Information Real-time Multicast performance statistics can be obtained for a Multicast Source by selecting the Performance tab in the Contents panel. The Performance view provides a real-time graphical view of Source traffic. The information provided in the Performance view is useful for monitoring Multicast performance and faults within the Multicast environment. For this graph to function properly, the following must be true: If you are able to create a physical device model of the Source, you should model it as an SNMP host. You can choose one of SPECTRUM s host model types: Host_Compaq Host_Dell Host_Sun Host_systemEdge Host_Device GnSNMPDev 28 Multicast Manager User Guide

37 Multicast Source Management If you are not able to create a physical device model of the Source, you should model the Source as a pingable. The Multicast Discovery process will create pingable models automatically for all Multicast Sources that do not have a corresponding physical device model. See Multicast Discovery on page 12 for more information. SPECTRUM must be able to communicate with the Source. The default gateway for the Source must be modeled in SPECTRUM using the appropriate router model type. If you model the Source as a pingable, the default gateway must be correct in the Source model s Configuration view. For instructions on verifying the default gateway see Configuration on page 26. SPECTRUM must be able to communicate with the default gateway for the Source. The default gateway must support one of the IPM Route MIBs (draft or RFC). The routers in a Hot Standby Routing Protocol (HSRP) group must be set to send HSRP traps to the SpectroSERVER for Multicast Manager performance monitoring to work properly, and for performance graphs to show traffic statistics when the active router in the HSRP group has changed because of a failover. To set the configuration parameters that control how the Group Performance view is displayed and the alarms that are triggered based on performance, see Multicast Manager Configuration on page 5. Define a Proxy for an Unmanageable Source Multicast Manager allows you to define a proxy to monitor an unmanageable source. Examples of an unmanageable source (or Multicast stream) are groups which originate outside of your network. These could be feeds which traverse the internet to get to this location or dedicated services like financial data streams which are purchased to feed trading applications. The proxy should ideally be the ingress router where the Multicast Stream enters the network. Since you cannot monitor the source, you can configure the ingress router where the Multicast Stream enters the network to represent the unmanageable source for performance comparisons. To define a proxy 1. Conduct a Multicast Search for the unmanageable source model. The results of the search display in the Contents panel. 2. Select the unmanageable source model from the results list. Information and configurations display in the Information tab of the Component Detail panel. Managing the Multicast Network 29

38 View Alarms 3. Expand the Configuration sub-view. The Default Gateway and Proxy IP configuration parameters display. 4. Click set next to Proxy IP and enter the IP Address of the ingress router where the Multicast Stream from the unmanageable source enters your network and press Enter. The IP Address of the unmanageable source s proxy displays. View Alarms The Contents panel displays the Alarm list for the modeled element that you have selected in the Navigation panel. Further information about an alarming element can be found in the Alarm Details tab of the Component Detail panel.

40 View Multicast Topology Information View Multicast Topology Information The Multicast Topology view provides you with a graphical representation of the data flow from a Multicast source through the associated devices, and allows you to more easily troubleshoot and gauge the overall impact of traffic flow changes and outages within your environment. You can access a Topology view, such as the one shown in the figure in the following procedure, for each source within a Multicast Group that Multicast Manager has discovered and modeled. The performance information for each segment of the traffic distribution tree displays the percentage of source traffic reaching that segment. The percentage is calculated by comparing the baseline traffic from the source. Note: Performance Analysis must be enabled on the Multicast Manager model and for any Multicast group you want performance information to be displayed for in the Multicast Topology view. For more information on enabling Performance Analysis on the Multicast Manager model, see Performance Analysis Configuration on page 9. For more information on enabling Performance Analysis on a Multicast Group model, see Performance Analysis Configuration on page 21. Note: The path structure and performance data displayed is based on the latest poll. It may not necessarily reflect the current state. 32 Multicast Manager User Guide
