Function name:
DSCP Setting
Function description:
In the late 1990s, the IETF redefined the meaning of the 8-bit SERVICE TYPE
field to accommodate a set of differentiated services (DS). Under the
differentiated services interpretation, the first six bits comprise a codepoint,
which is sometimes abbreviated DSCP, and the last two bits are left unused.
DSCP can form total 64 (0~63) kinds of Traffic Class based on the
arrangement of 6-bit field in DSCP of the IP packet. In the switch, the user is
allowed to set up these 64 kinds of Classes that belong to any level of queue
(low, normal, medium, high).
Parameter description:
DSCP Priority Mapping:
64 kinds of priority traffic as mentioned above, the user can set up any
level of Queue (low, normal, medium, high). In default, Priority 0~63 are
mapped to Queue high.
