For CAR ( applied via rate-limit command )
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Max Burst = Be Pls. note : Be is always greater than Bc here
Special Case: when No excess burst is allowed then Be=Bc
For Policing ( applied via service policy )
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Max Burst = Be+ Bc . Pls. note : Here Be could take any value between 0 and
Line rate .
Special case :when No excess burst is allowed then Be=0
Thanks and Regards
Arun
