Policy-map is wasting my BANDWIDTH

hello , i have asr1006 and i used it for PPPOE server for user

 For example 

500 users is connected to router via PPPOE 

and they have all of them downloading file

and i config when user connected he get Policy-map

Policy Map user

  Class class-default

   police cir 100000 bc 3125

     conform-action transmit

      exceed-action drop

 

so if all of them downloading in same time

they traffic must be 500Mbps ,

but i see they input interface is have 700Mbps traffic And PRTG of my ISP Is read 700Mbps

 

 why ? and all of users  has policy-map and they traffic speed is limited to 1Mbps?

 

maybe they have dropped and the Send request to internet and internet replay to them so the traffic is has more of 500Mbps

 

 

how to limit user and when he have drop he must can’t send more upload packet 

 

* i use radus to set policy name when user connect 

* ii need to limit user a thought not just out or in

so if he have downloading 1mbps he can’t send more request to internet and that will save my traffic

Hello,

 

how do you have this set up, is this a test lab ? How do you simulate 500 users downloading files at exactly the same time ?

hello we are ISP , now i have my Router with 1000 real user is online ..

 

But i give you small example to understand my issue ,

 

another example 

1000 real user is online , and all of them has policy-map 1Mbps

but i can see they traffic more of 800Mbps or 900Mbps , and is imposable all of them downloading  download same ,

 

what i mean ,i need to policy-map user for thought traffic not two policy - upload/Download 

 

My analysis is all user have 1Mbps Download limited , but when user downloading and use all his traffic (1m) he have another policy-map for upload so he can send more request for example (browsing) , his request will get replay from internet  to my router , and my router will drop this packer because user have use all of 1mbps , but the packet already delivery to my router and this wasting my BANDWIDTH

Where are you measuring the aggregate bandwidth usage?

If, for example, as an ingress policy on an interface, ingress could exceed the policing limits, as the traffic enters the interfaces, but shouldn't exceed the aggregate as forwarded to the egress interface(s).

If, the other hand, you have this as an egress policy, on an interface, then I would expect that interface not to exceed the aggregate unless there's other egress bandwidth not subject to the policy.

Hello, thanks for reply

let me give me your details,

my router has two interface

ten 0/0/0 is connect with my ISP

Ten 0/1/0 is has vlans with pppoe to my user's

 

so interface ten 0/0/0 is input my service

 

all user's in Ten 0/1/0 has limited with 1Mbps policy-map

 

but in peak-time traffic, for 500 user's has traffic more of 700Mbps

interface ten 0/0/0 input: 700Mbps
interface Ten0 / 1/0 Ouput : 700Mbps


how that ? and all user's is have limit traffic with 1Mbps

so if they are all of them downloading files in same time (and that's imposable) the Will not exceed 500Mbps , but the real traffic from my ISP is 700Mbps

Again, what interface(s) and what direction(s) (i.e. in or out or both) is policy assigned?

Hello,

 

looking at your output:

 

Class-map: class-default (match-any)
14559817 packets, 2670943646 bytes
30 second offered rate 18000 bps, drop rate 0000 bps

transmit
exceeded 75791 packets, 105166670 bytes; actions:
drop
conformed 18000 bps, exceeded 0000 bps

 

--> cir 10000000 bps equals 10Mbps, not 1Mbps

hello , thanks for replay,  yes in config i was open 10Mbps in night time

 

 

but i mean in peak-time traffic  i give user1' 1Mpbs 

 

 

Policy Map user

  Class class-default

   police cir 100000 bc 3125

     conform-action transmit

      exceed-action drop

but the are using  more than expected traffic

Hello,

 

Policy Map user

Class class-default

police cir 100000 bc 3125

conform-action transmit

exceed-action drop

 

I think the value is in bits per second, so you need to add a '0' for one Mbit. 100000 means 0.1 Mbit.

hello ,thanks for reply 

don't care about some text error 

 

 

i mean when use limit

 

Policy Map user

Class class-default

police cir 1000000 bc 3125

conform-action transmit

exceed-action drop

 

for 500 user'

the in interface traffic is going to more of 500Mbps (600 or 700 )

so how that's and all user's has limit traffic for 1Mbps

 

 

 

 

 

any idea how to limit use for throughput not just upload or download  
so if he download file with speed 1Mbps
he can't upload file in  same time
