Fig. 14 Multicast Configuration Panel#

This panel contains configuration options that control the generation of multicast traffic.

Multicast Protocol Profile and Version#

  • Protocol Profile

    The protocol segment profile to use for the multicast traffic.

  • IGMP/MLD Version

    Specifies the IGMP or MLD version to use. Note that the IP version is implicitly selected in the Protocol Profile option described above.

Multicast Address Range#

  • Start Address (IPv4)

    The starting address to use when allocating a multicast group address sequence. Only valid if IPv4 is selected through the protocol profile.

  • Start Address (IPv6)

    The starting address to use when allocating a multicast group address sequence. Only valid if IPv6 is selected through the protocol profile.

  • Step Value

    The step value used to increment the address when generating a multicast group address sequence.

Protocol Registration Handling#

  • Join Refresh Interval

    The interval in seconds with which the join requests will be retransmitted. This is useful for longer-running tests where the router may otherwise timeout the individual learning requests.

  • Join/Leave Rate

    The maximum rate with which the IGMP Join or Leave packets are sent. This is used to spread out the request transmission to prevent the DUT from being overwhelmed and drop requests.

  • Use Source Address

    If selected the multicast address will be added as a source address to the IGMPv3/MLDv2 Group Record in the Join/Leave requests. If not selected the Group Records will not contain any source addresses. See RFC 3376 #section-4.2.9 for details.

  • Leave to AllRouters

    If selected, Leave Group messages are sent to the all-routers multicast group (224.0.0.2) If not selected Leave Group messages are sent to the multicast group address

Test Payload#

  • Payload Type

    The type of test payload in the packets generated by the MC source port.

  • Pattern

    If the payload type has been set to “Pattern” you can specify the pattern here.

Packet Rate#

  • Fraction

    This option allows you to specify the overall rate used for the multicast stream as a percentage of the physical port rate.

  • Packet/sec

    This option allows you to specify the overall rate used for the multicast stream as a packets per second value.
