LTM V11.2 rate shaping - rateclass not working as expected

OK, I thought I'd read up on this just to be sure. It's still not 100% clear from this: http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-concepts-11-3-0/tmos_rateshaping.html?sr=26769961 - "A rate class defines the throughput limitations and packet scheduling method that you want the BIG-IP system to apply to all traffic that the rate class handles".

 

 

So, I read that as;

 

1) If you apply the RC via a Packet Filter (and nothing else) anything that matches is handled by the specified RC (it applies to all matching flows)

 

2) If you apply the RC via a VS (and nothing else) anything that uses that VS is handled by the specified RC (it applies to all combined flows handled by the VS)

 

3) If you apply the RC via an iRule (and nothing else) anything you specify in the iRule to use the RC does (this could be a single connection or a source subnet or whatever)

 

 

So, in your case I'd suggest go for 3) if you can identify the clients easily (by source IP hopefully). Hope this makes sense.
