Explanation

During a failover event in Cisco IM&P high availability, all clients from the failed primary node attempt to re-login to the secondary node simultaneously. This surge can overwhelm the secondary node and disrupt users who were already connected to it. The 'CUPC 8.5 And Higher - Re-Login Limits' parameter on the Server Recovery Manager service controls the rate and maximum number of client re-logins permitted during a failover, acting as a throttle. By tuning this limit, the engineer ensures the secondary node is not flooded, preserving service for existing users while gradually accepting the re-logging clients. The other options affect SIP proxy capacity, database request limits, and presence engine polling - none specifically govern client re-login rate during failover.
