CIR – The Committed Information Rate can be set between 1 and 156249. The color rates are
based on the following two fields which are used in conjunction with the CIR.
CBS – Committed Burst Size. Measured in bytes, the CBS is associated with the CIR and is
used to identify packets that exceed the normal boundaries of packet size. The CBS should be
configured to accept the biggest IP packet that is expected in the IP flow. Packet flows that are
lower than this configured value are marked green. Packet flows that exceed this value but are
less than the EBS value are marked yellow.
EBS – Excess Burst Size. Measured in bytes, the EBS is associated with the CIR and is used to
identify packets that exceed the boundaries of the CBS packet size. The EBS is to be configured
for an equal or larger rate than the CBS. Packet flows that exceed this value are marked as red.
Action This field is used to determine the course of action when a packet flow has been marked as a
color, based on the following fields.
Conform This field denotes the green packet flow. Green packet flows may have their DSCP field
rewritten to a value stated in this field. Users may also choose to count green packets by ticking
the Counter check box.
Exceed This field denotes the yellow packet flow. Yellow packet flows may have excess packets
permitted through or dropped. Users may replace the DSCP field of these packets by checking
its radio button and entering a new DSCP value in the allotted field. Users may also choose to
count yellow packets by ticking the Counter check box.
Violate This field denotes the red packet flow. Red packet flows may have excess packets permitted
through or dropped. Users may replace the DSCP field of these packets by checking its radio
button and entering a new DSCP value in the allotted field. Users may also choose to count
yellow packets by ticking the Counter check box.
