Are you trying to set a limit for bandwidth or just stopping transmitting after a counter?

 

You have already BWC and Rate Shaping to set bandwidth limits, which are more efficient:

 

RateShaping -> https://support.f5.com/kb/en-us/products/big-ip-aam/manuals/product/aam-concepts-12-1-0/4.html

 

BWC -> https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-implementations-12-0-0/8.html

 

Also, you can apply both using an iRule condition.
