3.
Enable multicast with the following:
configure interface cable-mac 1.0 ip igmp
configure interface cable-mac 1.0 ip igmp version 3
configure interface cable-mac 1.0 ip igmp proxy-interface gigabitethernet 17/0
configure interface cable-mac 1.0 ip igmp backup-proxy-interface gigabitethernet 18/0
Note that the following commands may be configured for either IGMPv2 or IGMPv3. In this example, IGMPv2 is
configured.
configure interface gigabitethernet 6/0.0 ip igmp
configure interface gigabitethernet 6/0.0 ip igmp version 2
configure interface gigabitethernet 7/0.0 ip igmp
configure interface gigabitethernet 7/0.0 ip igmp version 2
4.
Configure the fiber-node:
configure cable fiber-node FN1
configure cable fiber-node FN1 cable-downstream 14/0 14/1 14/2 14/3 14/4 14/5 14/6 14/7
configure cable fiber-node FN1 cable-upstream 1/0 1/1 1/2 1/3
Configure Bonding Groups
Downstream dynamic bonding must be disabled; requiring the configuration of all downstream bonding groups for the
following reason:
If a multiple downstream CM registers at a fiber node that carries more channels than the CM can support at one time,
then the C4/c CMTS must make a choice as to which channels to assign the CM to use for its downstream channel set. As
opposed to statically configured service flows, the C4/c CMTS does not know which channels a CM may need for any
dynamically created (for PCMM or IGMP, for example) service flows at the time that the CM registers. Since the C4/c CMTS
does not currently move a CM’s downstream channels after it registers, all static bonding groups must be configured to
include the channels that may be assigned to the dynamic service flows.
This example displays how to disable dynamic downstream channel bonding on the cable-mac and create two static
bonding groups for the HSD and video configurations.
