CDM-840 Remote Router Revision 2
Appendix C MN-CDM840
C–7
If required, you can create QoS rules with “Filter All” enabled to filter undesired Multicast from
traversing the satellite network for both the CTOG-250 and the CDM-840.
C .5.1 Multicas t Management/R outed B ehavior (no change)
In both BPM and Router Modes, Multicast packets arriving at the Management (routed) port of
the CTOG-250 and CDM-840 must be configured to be transmitted to the WAN by adding a
Multicast-specific route table entry with a “/32” subnet.
Packets arriving at the CDM-840 downlink pass out the CDM-840 Ethernet port based upon the
following criteria (configurable via NetVue or the Web page for each CDM-840):
• Downlink (outbound from the Hub Segment) Multicast All – All downlink outbound
Multicast packets pass to the Traffic LAN interface of the CDM-840 unit.
• Use IGMP (Internet Group Management Protocol) – Only remotes that have IGMP
clients enabled with the Multicast address pass the Multicast packet to the CDM-840’s
LAN port.
C.6 BPM and Group QoS with Outbound ACM/VCM
Figure C-7. Configuring VLAN to QoS Group Mapping
ACM/VCM on the Outbound carrier works with BPM by seamlessly matching packets to the
correct remote site. While no configuration is required, you have the ability to first use a VLAN
