hi folks,


in a policy map, when I use the 'police' command without transmit/exceed/violate action specifications, there's an implicit exceed-action drop?


Example:

policy-map Test

class X-Traffic

police 64000

exit


In this case, I've a policer always-on for the X-Traffic, and traffic exceeded 64k will be dropped?


Thanks for your support

Regards

Andrea

Yes the traffic will be dropped if it exceeds the rate you have configured.


If you do not want the traffic to be dropped, you can instead shape the traffic (provided the traffic is not delay sensitive)


Policing discards excess packets, so that overall policed rate is not exceeded whereas shaping enqueues the excess packets which are removed from the queue at the shaped rate


HTH, rate if it does
