We are in the process of upgrading our Local Directors to CSM blades but functional testing has indicated that the CSM's are failing to redirect connections to a healthy real server when one of the real servers has failed and the failed_interval timer has expired. Instead of being redirected to a healthy real server the client is sent a TCP RST. We are using inband health monitoring to detect a server failure.
Is it possible to configure the equivalent of the Local Director reassign parameter on the CSM's so that the client doesn't experience any loss of service when a real server fails?
LocalDirector counts the number of TCP SYN packets per connection. When the number of allowable retries is exceeded, LocalDirector reassigns the next TCP SYN packet for the connection to another real server
