Creating a Multicast Profile
This topic describes how to create a multicast profile that enables provisioning of the IPTV
service limits that can be applied when adding an Ethernet service to an xDSL port. A
multicast profile is defined by the parameters listed below and references two previously
defined profiles:
Multicast Address Map
Identifies the optional global allowable multicast IP ranges. See Creating a Multicast
Address Map and Ranges.
Multicast VLAN Registration (MVR) Profile
Identifies the optional MVR address ranges associated with specified multicast VLANs.
See
Creating a MVR profile and MVR VLAN Addresses
(on page
111
).
Parameters
You can provision the following parameters for multicast profiles:
Parameter
Description
Valid Options
Name*
Name of the multicast profile.
32 character string
Max Streams*
Maximum number of multicast streams allowed at the subscriber port.
This value should include the boot channels, the programming guide,
and any other channels that may be learned, in addition to the number
of STBs on the port.
1-128
Multicast Maps
Identifies the map of optional global multicast IP addresses that a
subscriber service can join when this multicast profile is used. The
multicast map is an optional parameter of the multicast profile. With no
multicast address map identified, multicast group destination addresses
are unconstrained.
Any established multicast
map
MVR Profile
Identifies the optional MVR profile to be used by this multicast profile.
Note:
An MVR profile cannot be paired with more than one multicast
map.
Any established MVR profile
General Query
Interval
The value in seconds that matches the upstream router's general query
interval.
Note:
General Query Interval is NOT applicable for VDSL services.
In the absence of a channel join, the ONT keeps the channel active for
the query interval before cutting it off. The assumption is the router
sends a general query every interval which causes the set-top box to
join the channel which also keeps the channel alive.
10-3600
240 ‡
Convert to Unicast
Whether to convert multicast packets to unicast before sending them
out the subscriber Ethernet port.
The Convert to Unicast parameter should ONLY be enabled if switches
are deployed on the subscriber side that cannot manage heavy
multicast traffic.
Note:
Convert to Unicast feature is only applicable to the Calix GX
ONTs.
selected=enabled
unselected=disabled
* Required
‡ Default
