2.3.4.2 ToS/DiffServ Mapping
Fig. 2.12
The switch can classify traffic based on a valid DiffServ (ToS) priority tag; Fig. 2.12 shows
where users can map ToS to the different priority queues.
Table 2.7
Label Description Factory Default
Level
Sets the mapping table of different ToS to
4 distinct output queues, which are Q0
(lowest), Q1 (los), Q2 (median), and Q3
(highest). ToS 0~15: Q1
ToS 16~31: Q0
ToS 32~47: Q2
ToS 48~63: Q3
For example, when ToS 0*F8 (62) is assigned to Q3, it has the highest priority. When ToS
0*40(16) is assigned to Q1, it has the lowest priority. For ToS explanations please refer to
