QoS Overview
If user has configured any value greater than 0 and less than 64 then operation rate configured on
hardware would be 64 kbps irrespective of the constraint used.
Committed Burst Size
The committed burst size parameter specifies the maximum burst size that can be transmitted by
the source at the CIR while still complying with the CIR. If the transmitted burst is lower than the
CBS value then the packets are marked as in-profile by the meter to indicate that the traffic is
complying meter configured parameters.
Maximum Burst Size
For trTCM, the maximum burst size parameter specifies the maximum burst size that can be
transmitted by the source at the PIR while complying with the PIR. If the transmitted burst is
lower than the MBS value then the packets are marked as out-profile by the meter to indicate that
the traffic is not complying with CIR, but complying with PIR.
For srTCM, the maximum burst size parameter specifies the maximum burst size that can be
transmitted by the source while not complying with the CIR. If the transmitted burst is lower than
the MBS value then the packets are marked as out-profile by the meter to indicate that the traffic is
not complying with CIR.
If the packet burst is higher than MBS then packets are marked as red are dropped.
