The AF/EF Codepoints mask is displayed. Priorities are assigned in the form of hexadecimals.
● AF: guarantees minimum bandwidth for the data from one of a number of classes. Lower
priority classes share the bandwidths not used by EF or other high-priority classes. A
"Dropping Level" can be defined for every class; this specifies the speed at which packets
are rejected if the system is unable to forward them fast enough.
● EF: guarantees constant bandwidth for this data. If this defined value is reached, all pack-
ets that would exceed this bandwidth are rejected.
Four classes are reserved for AF:
● AF1x (lowest priority)
● AF2x
● AF3x
● AF4x (highest priority).
In the AF class, the value x stands for the "Dropping Level":
● 1 (low), packets are buffered for an extended length of time
