5. Multicast service configuration 57
www.qtech.ru
5.3. Multicast bandwidth downlink rate limit
OLT (config-gpon-olt1 / 4) # scb max-bandwidth 200000
It must be configured in "qos-queue-scheduler mode hierarchy" mode, if it is in switch mode you
need to manually shutdown PON port before switching.
OLT (config-xe1 / 2) # storm-control multicast kbps 5000
Configuration will be valid in “qos-queue-scheduler mode simple” and
“qos-queue-scheduler mode hierarch”.
When the PON port SCB multicast flow rate and uplink port of storm-control are both configured,
the lower data rate will be effective.
IGMPv3 Snooping Description:
For IGMPv3, the snooping that supports type1.2.3.4 only follows the following rules. Type1 - is include:
It is “include” with source, and “exclude” without source. Type2 - is exclude: It is “include” without
source, and “exclude” with source.
Type3 - change to include: It is “include” with source, and “exclude” without source. Type4 - change
to exclude: t is “include” without source, and “exclude” with source.
Maximumly 16 table entries is supported at present.
IGMP Run version will be automatically adjusted at uplink port, so if you need to receive V3 report,
the query should be sent.
MLD only supports version v1.
IGMP v3 Proxy Description:
This function send the source IP which didn't join the group, there are two scenarios:
When the uplink port didn't issue v3-query, the default version is V2, so the V2 report will be transferred;
When the uplink port issue v3-query, then V3 report will be transferred, where type is the fixed type4
(change to exclude).
When the packet carries type 5 or type 6, the OLT discards the corresponding source group information.
Span-VLAN configuration tips:
When configuring Span-VLAN multicast, need to pay attention to the order of configuration, firstly to
configure the converted MVLAN, or don't configure the user-vlan MVLAN related parameters,
otherwise it could be unable to join the group.
The planned IGMP VLAN, and MLD VLAN cannot be the same VLAN.
