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.

used first when making priority decisions.
PPPoE Control
Message
Priority
Operators may configure the AP to utilize the high priority channel
for PPPoE control messages. Configuring the AP 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.
