F5 Connection Rate Limit for VIP

Has anyone implemented Connection Rate Limit under the Virtual Servers -Advanced Configuration what do clients see after the particular rate limit is setup for a VIP.

Clients sending requests after the Connection Rate Limit has been exceeded will receive TCP packet in response where RST flag is set to 1. Or in other words, just "Connection Reset".

 

Note that this applies to entirely new connection attempts (handshakes), any existing connections will not be interrupted in case of threshold breach.

Hi,

 

"Currently, no matter how high I set the Connection Rate Limit the VS goes back to "Unavailable (Enabled)"

 

Before the limit is breached, the status should be Green or Blue (depending on if you use health-check monitors against pool members). Only after the limit is breached, it should switch to Yellow. Recommend to contact support with that, seems like unintended outcome.
