You may set the following Differentiated Services Configuration page parameters.
CodePoint 1
through
CodePoint 47
CodePoint 49
through
CodePoint 55
CodePoint 57
through
CodePoint 63
The default priority value for each settable CodePoint is shown in
Figure 113. 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 BHM for the downlink and in the BHS for the uplink. See DSCP
Field on Page 87.
