View Multicast Interface Statistics

Learn how to view multicast statistics for an interface in Prisma SD-WAN.
You can choose to view multicast statistics for the interfaces with multicast enabled.
  1. Select
    Map
    Claimed Devices
    Configure the device
    Routing
    Multicast
    Statistics
    .
  2. Select an interface to view the neighbor information for the interface.
    The neighbor information table displays information about the PIM neighbors discovered by the ION device for an interface across all multicast enabled interfaces in the network.
    Field
    Description
    Neighbor IP
    Displays a neighbor’s IP address.
    DR
    Indicates if the neighbor is a designated router.
    DR Priority
    Indicates the priority associated with the interface on the device for DR election.
    Uptime
    Indicates the time for which the neighbor has been up.
    Expires
    Indicates the time remaining before a neighbor is timed out and the next PIM Hello message is received.
  3. Click
    Statistics
    to view detailed multicast traffic, IGMP, and PIM statistics for the interface.
    The descriptions for the fields are based on descriptions outlined in RFC 2362 (https://www.rfc-editor.org/rfc/rfc2362.html) and RFC 2236 (https://datatracker.ietf.org/doc/html/rfc2236)
    Multicast Traffic Statistics
    Field
    Description
    RX PKTS
    Indicates the number of multicast traffic packets received at the interface.
    RX BYTES
    Indicates the volume of multicast traffic received in bytes at the interface.
    TX PKTS
    Indicates the number of multicast traffic packets transmitted from the interface.
    TX BYTES
    Indicates the volume of multicast traffic sent in bytes at the interface.
    PIM Statistics
    Message Type (MSG TYPE)
    Description
    Received Packets (RX PKTS)
    Transmitted Packets (TX PKTS)
    Hello
    Periodic messages sent between PIM neighbors aid in discovery of neighbors and maintaining the relationship with neighbors.
    Displays the packets received for a PIM Hello message.
    Displays the packets sent for a PIM Hello message.
    Register
    A DR sends a message to an RP indicating interest in receiving multicast traffic meant for a group.
    Displays the packets received for a PIM Register message.
    Displays the packets sent for a PIM Register message.
    Register Stop
    The ION device acting as an RP indicates to the DR when either of the following conditions are met:
    • There are no active listeners, so receivers have stopped requesting multicast information from the RP.
    • The RP stops serving a multicast group.
    • Multicast traffic has switched from a Rendezvous Point Tree (RPT) to the Shortest Path Tree (SPT).
    Displays the packets received for a PIM Register Stop message.
    Displays the packets sent for a PIM Register Stop message.
    Join/Prune
    Routers send Join/Prune messages to join a branch or prune off a branch from the multicast distribution tree. A single message contains a join listas well as a prune list.
    Join messages are sent by:
    • DRs (near receivers) to RPs indicating an interest in receiving multicast traffic via RPT.
    • DRs to source when triggering SPT switchovers.
    • RPs to source when triggering SPT switchovers.
    Prune messages are sent by PIM devices to upstream devices to stop forwarding multicast traffic to the network segment in which the PIM device resides.
    Displays the join and prune packets received for a PIM Join/Prune message.
    Displays the join and prune packets sent for a PIM Join/Prune message.
    IGMP Statistics
    IGMP statistics indicate the number of messages exchanged between individual hosts in a LAN and multicast routers to dynamically register with or unregister from a multicast group. Routers periodically send out IGMP queries to check which multicast groups are active or inactive in their subnet. Hosts send out IGMP membership reports for a particular multicast group to indicate their interest in joining that group.
    Message Type (MSG TYPE)
    Description
    Received Packets (RX PKTS)
    Transmitted Packets (TX PKTS)
