Policing: Calculate burst rate

Unanswered Question
Jun 13th, 2009

Looking at configuring policing on a layer3 port on a 6500 switch. How do I calculate the burst rate to limit the port to allow a max of 600MB ingress/egress on a 1GB port

### 6500 ###

!- QOS

mls qos

!- ACL

access-list 101 permit tcp 172.16.35.152 0.0.0.0 172.18.0.0 0.0.0.255

access-list 101 permit tcp 172.16.38.100 0.0.0.0 172.18.0.0 0.0.0.255

access-list 102 permit tcp 172.18.35.125 0.0.0.0 172.16.0.0 0.0.0.255

access-list 102 permit tcp 172.18.38.100 0.0.0.0 172.16.0.0 0.0.0.255

!- class map

class-map Police

match ip address 101

match ip address 102

!- Policy map

policy-map Traffic

class Police_OUT

police 600000000 conform-act transmit exceed-act drop

Please advise.

!- L3 Port

int G5/1

service-policy in traffic

service-policy out trafic

I have this problem too.

I don't think the 6500 will support full MQC. Commands like police, bandwidth, etc. are not going to be taken.

Can anyone else confirm?

Sorry, just realized I gave you an answer that provided zero help. You will want to check out the 6500 documentation for PFC QoS. Specifically the sections for aggregate and micro-flow policers. Basically, you build the mls qos aggregate-policer, then apply that to the class-map.
