Rate Shaping

i set a rate limit but in bandwidth 3600Kbs with a irule but i need to know if it will work...

 

when CLIENT_ACCEPTED {

 

if { [class match [IP::client_addr] equals SmartWizard_rate_limit] } {

 

log local0. "[IP::client_addr] being handled by rateclass class1"

 

rateclass Class1

 

}

 

}

isn't it number of requests?

 

 

max_rate_per_minute

 

The maximum number of requests that can take place per minute. ‘0’ means ‘no limit’.

 

 

max_rate_per_second

 

The maximum number of requests that can take place per second. ‘0’ means no limit.

TCL error: /Smart_Wizard/SmartWizard_rate_limit - undefined reference to rate class 'Class1' (line 3) invoked from within "rateclass Class1"

Hi Niass

 

 

Yes it is number of reques...

And doesn't look like the rate shapeing is working...

And doesn't look like the rate shapeing is working...i do not think rate shaping counts number of requests/connections.

 

 

i think you may have to do something like this.

well i decided to rate shape them to 512 only thing i could think of but i don't know if it's working...

Nitass, does the VS need to have a least one Rate Class applied in order for this to work?
