| Description | This represents one entry in the p2mpHistCtrlTable. This table
is indexed by ifIndex, p2mpHistSuMacAddress, and p2mpHistClass.
At the head end:
Histograms can be created on each upstream channel either on a
per channel or per subscriber unit basis.
When histograms are created on a per subscriber unit basis, the
user must specify the subscriber unit's MAC address and the
ifIndex of the MAC layer (propDocsWirelessMaclayer) at the
head end.
When histograms are created on a per channel basis, the user
must set the MAC address to zero(00 00 00 00 00 00). The
channel ID is specified by the ifIndex of the upstream channel.
Hence, when creating histograms on a per channel basis, the
ifIndex must be set to the ifIndex of the upstream channel
(propDocsWirelessUpstream) on which the histogram is to be
created.
At the subscriber end:
Histograms can only be created on the downstream channel. Since
there is only one downstream channel, histograms cannot be
created per channel ID. Hence, when a histogram is created, the
user must set the MAC address (p2mpHistSuMacAdress) to
zero(00 00 00 00 00 00). The ifIndex must be set to the ifIndex
of the downstream channel (propDocsWirelessDownstream). |
