DAS-3600 Series Ethernet over VDSL Switch CLI Reference Manual
Used to configure the multicast group which will be learned with the specific IGMP multicast
VLAN.
<vlan_name 32> [add | delete] profile_name <profile_name 1- 32
This command is used to configure the multicast group which will be learned by the specific
IGMP multicast VLAN. There are two cases that need to be considered. The join packet will
be learned with the IGMP multicast VLAN that contains the destination multicast group. If the
destination multicast group of the join packet can not be classified into any IGMP multicast
VLAN that this port belongs to, then the join packet will be learned with the natural VLAN of
the packet.
When an IGMP packet is received, first, it will check whether to be processed by the IGMP
snooping. If the IGMP snooping for the classified VLAN of this IGMP packet is enabled, it will
be processed based on IGMP snooping function. If the IGMP snooping for the classified
VLAN of this IGMP packet is disabled, then it will be checked whether to be processed by the
IGMP Multicast VLAN function.
There are some cases when an IGMP packet can be processed by IGMP Multicast VLAN. If
there are no profiles systemwise, and there is only one IGMP Multicast VLAN, then this IGMP
packet will be associated with this only IGMP Multicast VLAN.
If the packet is a tagged packet, the packet will be matched against the profile on this VLAN.
If matched, the packet will be associated with this VLAN. Otherwise, the packet is an
unmatched packet. If the packet is an untagged packet, the packet will be matched against
profiles on all IGMP Multicast VLANs. If it matches profiles on one of the IGMP Multicast
VLAN, the packet will be associated with this VLAN. If it does not match profiles on any
VLANs, then the packet is an umatched packet. If the packet is an unmatched packet, it will
not be processed by the IGMP Multicast VLAN. Instead, it will be processed based on the
forwarding mode for unmatched packets and the classified VLAN of this packet.
<vlan_name 32> − The name of the multicast VLAN to be configured, each multicast VLAN is
given a name that can be up to 32 characters.
add − Used to associate a profile to a multicast VLAN.
delete − Used to remove a profile from a multicast VLAN.
<profile_name 32> − The name of the IPv4 multicast VLAN group profile to be associated the
specified multicast VLAN.
Only Administrator and Operator-level users can issue this command.
Note: The same profile can not be overlapped in
different IGMP Multicast VLANs if these IGMP
Multicast VLANs have an overlapping portlist. Multiple
profiles can be added to a multicast VLAN.
