Hi Udo,

sorry for the late reply, just catching up with emails

after few days of break.

In my understanding:

police <cir> <bc> <be> configures a 1 rate policer.

police cir <cir> pir <pir> configures a 2 rates

policer.

when only <cir> is specified, both commands:

i.e.

police <cir> or

police cir <cir>

are identical.

Please look for "police" and "police (two rates) in

the cisco documentation below:

/qos_o1h.htm#wp1095717
