Configuring IP Multicast Address Mapping
You can configure and display an IP multicast address mapping entry, and set
the associated multicast SAID authorization for each cable modem on each
CMTS MAC interface.
Configuring an IP multicast address mapping and associated SAID involves
setting the following parameters:
Table 19-6 Parameters for Setting and Displaying IP Multicast Address
Mappings
Parameter Description
index An index value that identifies the multicast
mapping entry.
multicast-ip-address Specifies the Class D IP address (for example,
239.1.1.1) of the multicast group to which you
are applying the security association specified
by the SAID.
mask Specifies the mask, in dot-notation format, that
can be used with a single multicast group
address or to specify a multicast address range.
For example, a multicast address of 239.1.0.0
and a mask of 255.255.0.0 means that the SA
applies to all multicast groups within 239.1.0.0.
For a single multicast group address (for
example, 239.2.2.2), specify a mask of
255.255.255.255.
mac-address The MAC address of the CM that is authorized
to access the defined multicast stream via the
SAID.
SAID The multicast SAID used in the multicast
address mapping entry. Allowable value ranges
are 8192 to 16383.
