The following additional information is displayed in the Probe Properties window for certain devices, such as Cisco CPT devices. Packets Per Burst The number of packets transmitted per burst. Burst Period The time taken to send the packets from the source to their destination. This period is usually specified in terms of seconds or milliseconds. Table 22-1 Y.1731 Content Pane (continued) Field Name Description Table 22-2 Probe Properties Window Field Name Description Delay Measurement Configurations Statistics Type The statistics type, which is Round Trip Delay or Round Trip Jitter. Aggregate Bin Count The aggregate count of bins to store the counter values of the result of each performance parameter. NoteThe counter value refers to the counter of number of results that fall within a particular range specified for each performance attribute. Aggregate Bin BoundariesThe bin boundary for the bins. For some devices, such as Cisco CPT devices, the bin boundary is specified as comma separated intervals; for other devices, such as the Cisco ASR 9000, it is an integer.

Bin boundaries are specified in terms of milliseconds. Bucket Size The number of buckets required to store the performance attribute results gathered during a specified period. By default, a separate bucket is created for each probe, which will contain the results relating to measurements made by the probe. Aggregation Period The period of time during which the aggregation must take place on the loss data. Aggregate Burst Cycles The total number of burst cycles on which the aggregation must take place. Availability Algorithm The type of algorithm to be used to measure proportion of time when there was a prolonged high loss, which can be any one of the following: Consecutive Frames The number of consecutive frames that must be used to calculate frame loss. NoteFrame loss is calculated by comparing loss measurement data of the specified number of consecutive frames. Consecutive Frames For Loss RatioThe number of consecutive frames that is used to calculate loss ratio. NoteThe Frame Loss Ratio is calculated as a ratio between the number of packets sent and the number of packets lost, which is then expressed in terms of percentage.

CH A P T E R 23-1 Cisco Prime Network 4.3.2 User Guide 23 Monitoring IP and MPLS Multicast Configurations IP Multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to thousands of corporate recipients and homes. Applications that take advantage of multicast include video conferences, corporate communications, distance learning, and distribution of software, stock quotes, and news. IP Multicast delivers source traffic to multiple receivers without adding any additional burden on the source or the receivers while using the least network bandwidth of any competing technology. Multicast packets are replicated in the network by Cisco routers enabled with Protocol Independent Multicast (PIM), Multicast Label Distribution Protocol (MLDP) and other supporting multicast protocols resulting in the most efficient delivery of data to multiple receivers possible. Multicast is based on the concept of a group. An arbitrary group of receivers expresses an interest in receiving a particular data stream. This group does not have any physical or geographical boundaries—the hosts can be located anywhere on the Internet. Hosts that are interested in receiving data flowing to a particular group must join the group using Internet Group Management Protocol (IGMP). Hosts must be a member of the group to receive the data stream. For information on the devices that support IP and multicast, refer to Cisco Prime Network 4.1 Supported VNEs. These topics provide an overview of the IP Multicast technology and describe how to view IP and multicast configurations using the Vision client. If you cannot perform an operation that is described in these topics, you may not have sufficient permissions; see Permissions for Managing IP and MPLS Multicast, page B-20. Viewing Multicast Nodes, page 23-1 Viewing Multicast Protocols, page 23-3 Viewing the Address Family (IPv6) Profile, page 23-4 Prime Network also provides multicast support for: MPLS services. See Multicast Label Switching (mLADP), page 17-44. Routing entities. If you have configured multicast route information for a VRF, the Vision client displays a separate tab for the related VRF wherein you can view the multicast routing information. See Viewing Routing Entities, page 17-32and Viewing VRF Properties, page 17-28.

Step 2In the Inventory window, choose Logical Inventory>Multicast>Address Family (IPV6). The profile details are displayed in the content pane. Table 23-3 describes the fields that are displayed in the Address Family (IPV6) profile. Table 23-2 Address Family (IPV4) Profile Field Name Description MDT Source Interface The source interface to set the multicast VPN data. NoteThis interface can identify the root of the MDT in the service provider network. This interface and its corresponding address is used to update all Multicast VPN (MVPN) peers through multiprotocol Border Gateway Protocol (BGP). MDT Static The interface used for transporting MDT data. Interface All Indicates whether the multicast routing and protocols are enabled on the interfaces. NoteYou must enable the interfaces using the Interface command in the multicast-routing configuration mode. NSF Status Indicates whether the non-stop forwarding capability is enabled for all the relevant components. NoteIf this feature is enabled, then multicast forwarding will not stop on failure of the control plane multicast routing components. Address Family The address family, which in this instance is IPV4. MDT MLDP Indicates whether the Multicast Distribution Tree (MDT) Multipoint Extensions to Label Distribution Protocol (MLDP) in-band signalling is enabled.
23-5 Cisco Prime Network 4.3.2 User Guide Chapter 23 Monitoring IP and MPLS Multicast Configurations Viewing the Address Family (IPv6) Profile Viewing the IGMP Profile The IGMP runs between hosts and their immediately neighboring multicast routers. The mechanisms of the protocol allow a host to inform its local router that it wishes to receive transmissions addressed to a specific multicast group. Also, routers periodically query the LAN to determine if known group members are still active. If there is more than one router on the LAN performing IP multicasting, one of the routers is elected querier and assumes the responsibility of querying the LAN for group members. Based on the group membership information learned from the IGMP, a router is able to determine which (if any) multicast traffic needs to be forwarded to each of its leaf sub networks. Multicast routers use this information, in conjunction with a multicast routing protocol, to support IP multicasting across the Internet. Table 23-3 Address Family (IPV6) profile Field Name Description Interface All Indicates whether the multicast routing and protocols are enabled on the interface. NoteYou must enable the interfaces using the Interface command in the multicast-routing configuration mode. NSF Status Indicates whether the non-stop forwarding capability is enabled for all the relevant components. NoteIf this feature is enabled, then multicast forwarding will not stop if the control plane multicast routing components fail. Address Family The address family, which in this instance is IPV6. MDT MLDP Indicates whether the Multicast Distribution Tree (MDT) Multipoint Extensions to Label Distribution Protocol (MLDP) in-band signalling is enabled. MDT Static The interface used for transporting MDT data. MDT Source Interface The source interface to set the multicast VPN data. NoteThis interface can identify the root of the MDT in the service provider network. This interface and its corresponding address is used to update all Multicast VPN (MVPN) peers through multiprotocol Border Gateway Protocol (BGP).
