Attribute Meaning
Codepoints 1 through
63 The PMP family of APs support four levels of QoS. The mapping of these
eight priority values to data channels is determined by the number of data
channels configured per SM as shown in the table below:
For example, for an AP that uses the default table shown above has
configured 3 QoS levels per SM, would see codepoints 0 through 15 mapped
to the Low Priority data channels, codepoint 16 would be mapped to the
Medium Priority data channels, and so on.
Note that CodePoints 0, 8, 16, 24, 32, 48, and 56 are predefined to the fixed
values shown in
Table 20 above and are not user configurable. Operator
cannot change any of these three fixed priority values. Among the
configurable parameters, the priority values (and therefore the handling of
packets in the high or low priority channel) are set in the AP/BHM for all
downlinks within the sector and in the SM/BHS for each uplink.
CodePoint Select This represents the CodePoint Selection to be modified via Priority Select.
Priority Select The priority setting input for the CodePoint selected in CodePoint Select.
Priority Precedence Allows operator to decide if 802.1p or DiffServ priority bits must be used
first when making priority decisions.
PPPoE Control
Message Priority Operators may configure the AP/BHM to utilize the high priority channel for
PPPoE control messages. Configuring the AP/BHM in this fashion can benefit
the continuity of PPPoE connections when there are issues with PPPoE
sessions being dropped in the network. This prioritization may be configured
in the DiffServ tab in the Configuration menu of the AP/BHM.
MPLS Traffic Class
(TC) 0 through MPLS
Traffic Class (TC) 7 The Multi-Protocol Label Switching (MPLS) protocol is used to route traffic
based on the priority setting configured each MPLS Traffic Class.
MPLS Traffic Class (TC) 0 through MPLS Traffic Class (TC) 7 can be
configured with 0 through 7 priority settings.
IPv4 and IPv6 Filtering
The operator can filter (block) specified IPv6 protocols including IPv4 and ports from leaving the
AP/BHM and SM/BHS and entering the network. This protects the network from both intended and
inadvertent packet loading or probing by network users. By keeping the specified protocols or ports off
the network, this feature also provides a level of protection to users from each other.
