I'm not positive this is what you're asking but if you want to know the
difference between rate-limit and police during times when there's not
congestion, then the answer is the same.
Both rate-limit and police set a maximum amount of bandwidth that can be
used and this maximum can not be exceeded regardless of whether or not
there's congestion.
Be aware, however, that when you use MQC, the most bandwidth that can be
reserved is 75% of interfaces' bandwidth.
This raises an interesting question:
Is the bandwidth specified with the police command in MQC considered
"reserved" and applicable to this max-reserved-bandwidth value?
IOW, suppose this were the configuration:
policy-map TEST
class A
police 500
class B
police 500
and the bandwidth on the interface is 1000. Will this config work?
TIA, Tim

Subject: RATE-LIMIT vs POLICE
Hi,
Can anyone here confirm me? I am thinking that 'RATE-LIMIT OUTPUT' command
under interface configuration is always on, regardless there is congestion
in
outgoing interface. And, 'POLICE' command under class/policy-map
configuration
will be activated if and only if there is congestion in outgoing interface.
This thought arise when I face problem to configure router to let Voice
traffic can consume 99% link bandwidth, when there is no data traffic. But,
when data traffic flows, the voice traffic get only 50% bandwitdh.
Am I right??
Regards,
Firebat
