class-map match-all cm_class4

match ip dscp default

class-map match-all cm_class3

match ip dscp af21

class-map match-all cm_class2

match ip dscp af31

class-map match-all cm_class1

match ip dscp ef

!

!

policy-map pm_inbound

class cm_class1

police cir 320000 bc 8192

priority

class cm_class2

bandwidth 900

queue-limit 128

class cm_class3

bandwidth 5900

queue-limit 407

class cm_class4

bandwidth 2300

queue-limit 407

class class-default

policy-map pm_from_ABC

class class-default

shape average 9500000

service-policy pm_inbound

Hi

Pls let me know how you are viewing the class utilisation in %.

I think you know that a class can utilise the bandwidth from other classes if they are free.

Hi,

actually i getting reports from lucent vital net ....there it shows ....utilizations for diffrent classs..so it comes like ....10-2000 % ..

[network.king]

Hi,

You might be polling based on the bandwidth assigned to various classes and if the traffic in other classes is free , then one class can utilise the entire bandwidth .

eg . If a 10M link and one class is configured for 1 M , and other classes are free , then this class would use the entire 10M.

Pls check the utilisation by pummping traffic in all the classes.

Hi Vanesh,

I got the answer...from your reply can you please clear my last doubt.

In configuration why we are using

# police cir 320000 bc 8192 for class1

for class 2 bandwidth is there .

policy-map pm_inbound

class cm_class1

police cir 320000 bc 8192

priority

class cm_class2

bandwidth 900

queue-limit 128

class cm_class3

bandwidth 5900

queue-limit 407

class cm_class4

bandwidth 2300

queue-limit 407

class class-default

but in this example

policy-map pm_outbound

class cm_class1

police cir 320000 bc 8192

priority

class cm_class2

police cir 400000 bc 8192

bandwidth 400

queue-limit 128

both the classes are having cir values.

can u pls explain the same.

[network.king]

In your policy-map inbound , you have policing for one class , so that class would not be able to more bw than specified .But the other two classes , the bandwidth specified is the guaranteed amount of bandwidth when all the classes are utilising .But if other classes are not using then any class except the policed one would use the free bandwidth.

So in your case , inbound policy-map two classes would be able to have some exceeded utilisation . But your outbound cannot have exceeded values and they should display you the correct utilisation.

Hope this helps
