Version: 1.5
Transmit and receive PDU sizes
Management mode modification per port
Max VPI/VCI bits (interface must be disabled)
Maximum number of VCCs supported
OAM source ID
3.6 Multicast Modes
IGMPv2 operation is provided and conform to RFC2236.
IVD supports IGMP snooping function
IVD supports configurable filtering of IGMP Membership Report messages.
IVD supports dropping of all IGMP messages received on a subscriber port.
IVD supports an IGMP v2 transparent snooping function. This feature is configurable on a per
VLAN basis.
IVD supports IGMP immediate leave as part of the IGMP snooping function.
IVD provides statistics on all active groups on a per-VLAN and per-port basis.
IVD allows the configuration of IP multicast groups or ranges of multicast groups per multicast
VLAN based on:
‧ Source address matching
‧ Group address matching
IVD is able to configure per DSL port the maximum number of simultaneous multicast channels
allowed.
IVD supports the Globally Scoped Multicast Addresses (224.0.1.0 – 238.255.255.255).
IVD supports the Limited Scoped Multicast Addresses (239.0.0.0/8).
IVD supports a mechanism to prevent a user port from becoming a multicast router port by
blocking IGMP query messages.
IVD supports mechanisms to stop user ports injecting unauthorized multicast traffic into the
aggregation network.
The DSLAM support IGMP Fast Leave.
N:1 VLANs forwarding mode is used in order allow efficient forwarding of multicast traffic. (It is to
be noted that other types of traffic (data, voice, unicast video) could be delivered via N:1 VLANs
as well.)
Dedicated Multicast VLAN model is supported. (This is a model where a dedicated N:1 VLAN is
used to send some multicast groups from a multicast router / BNG to one or several access nodes,
over an aggregation network. Other traffic is sent across different VLANs, where these VLANs
could be 1:1 or N:1.)
Integrated Multicast VLAN model is supported. (This is a model where multicast traffic is inserted
into one of the N:1 VLANs that are terminated at a subscriber DSL port, or alternatively dot1q
trunked to the RG. This effectively means multicast and unicast share a VLAN.)
