In the Diffserv tab of the SM, you may set the following parameters.
Table 9 SM Diffserv attributes
Attribute
Meaning
CodePoint 1
through
CodePoint 47
CodePoint 49
through
CodePoint 55
CodePoint 57
through
CodePoint 63
Priorities of 0 through 3 map to the low-priority channel; 4 through 7 to
the high-priority channel. The mappings are the same as 802.1p VLAN
priorities.
Consistent with RFC 2474
CodePoint 0 is predefined to a fixed priority value of 0
(low-priority channel).
CodePoint 48 is predefined to a fixed priority value of 6 (high-priority
channel).
CodePoint 56 is predefined to a fixed priority value of 7 (high-priority
channel).
You cannot change any of these three fixed priority values. Among the
settable parameters, the priority values (and therefore the handling of
packets in the high- or low-priority channel) are set in the AP for all
downlinks within the sector and in the SM for each uplink.

Priority Precedence
Allows operator to decide if 802.1p or DiffServ priority bits should be
used first when making priority decisions.
PPPoE Control Message
Priority
Operators may configure the SM to utilize the high priority channel for
PPPoE control messages. Configuring the SM 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 SM.
