CirrusConnection Rate Limits - How does BigIP respond?
I have an application where I may need to employ the "Connection Rate Limit" feature on an 11.4 LTM. If I configure this on the virtual server for 1000 requests per second, what sort of response, if ...
It will send TCP reset for connection rate limited virtual servers when the limit is reached.
See the bottom of SOL14813 - Detecting and Mitigating DOS/DDOS attacks (11.4.x/11.5.x)
Connection limit on pool members is really for resource management. When you reach the limit it will not send any new connection requests to that server until it falls back below the threshold. It does not affect existing connections.

CirrusPerfect, thank you!
For the second part about CRL on the pool members, I would now assume that if all pool members are at the maximum for that second, the VS would send RST to connection attempts in this case as well.
