The default priority value for each settable CodePoint is shown in
Figure 118. 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. See DSCP Field on Page 87.
The Diffserv tab of the SM also provides the following buttons.
