Table 18-16 Privacy IP Multicast Details Window Parameters
Parameter Description
IP Multicast Index Specify an index that identifies the multicast mapping entry.
Acceptable values are 1 to 10000.
IP Address Type Specify the internet address for an IP multicast address. At
this time, only ipV4 is supported.
IP Address Specify the Class D IP address of the multicast group to
which you are applying the security association specified by
the SAID.
IP Address Mask
Type
Specify the internet address for an IP multicast mask. At this
time, only ipV4 is supported.
IP Mask Specify the mask that can be used with a single multicast
group address; or, specify a multicast address range. For
example:
■ For a single multicast group address of 239.2.2.2, specify
a mask of 255.255.255.255.
■ For a multicast address range with an address of
239.1.0.0 and a mask of 255.255.0.0, the SA applies to
all multicast groups within 239.1.0.0.
Multicast SAID Specify the multicast SAID to be used in the multicast
address mapping entry. Acceptable values are 8192 to
16383.
SA Type Specify one of the following security association types:
■ none - No security association.
■ primary - Primary Security Association. This is tied to a
single cable modem and is established when that cable
modem completes CMTS MAC registration.
■ static - Static Security Association, which is provisioned
within the CMTS.
■ dynamic - Dynamic Security Association. This is
established and eliminated with the response to the
initiation and termination of specific (downstream)
traffics flows.
Both static and dynamic SA types may be shared by multiple
cable modems.
