Limitation of ICMP on Virtual Servers

Is there a built in limit for ICMP responses on Big-IP? Consistently it will stop at 249 example: Sending 250, 100-byte ICMP Echos to 192.168.1.40, timeout is 2 seconds: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!...

OK i found this information....: F5 has a limit to the ICMP rate which causes this droppage. Seen it before, it's an expected feature

 

But can anyone tell me "where" is this rate configured and what the rate is to be expected. Additional question if the Big-IP is configured to be a router do the devices that sit behind the Big-Ip fall into the same category. As I am seeing the same type of limitation for ip addresses that sit behind the Big-ip.....

 

Thanks in advance!
