Zeng,
You are right. If you configure both bc and be to the same value there is
no extended burst. In order to achieve your stated goal, then bc 1000 and
be 2000 would be correct.
Be careful when using these police commands, I would recommend that you
always use the ? prompt to determine whether you need to enter bits or
bytes.
Also the relationship between bc and be is different when using Traffic
shaping. When traffic shaping any value of be will be the absolute value of
the burst.

Subject: Bc and Be
Hi:
Could anyone clarify to me, when I asked to configure normal burst
size 1000 bytes, and excess burst size 1000 bytes for CAR or CB
policing, should I configure like this ".....bc 1000 be 2000" or just
"...bc 1000 be 1000".
Based on my understanding if Be is configured as 1000, then there is
no excess burst, is that right?
Thanks
Zeng
