Applies to

  • ActiveIQ Unified Manager (AIQUM)
  • SnapMirror

Answer

  • The ports that are found outside of the required ports mentioned in the ports requirement doc are ephemeral ports
  • Ephemeral ports, also known as dynamic ports, are temporary network ports used by client applications to establish outgoing connections with server applications like MySQL
  • When a Java application connects to a MySQL server, it dynamically selects any available ephemeral port from a range specified by the operating system
  • The range of ephemeral ports typically falls between 1024 and 65536
  • The ephemeral ports are temporary and released once the connection is closed
  • They cannot be reduced in the AIQUM application as they are essential for secure communication with the MySQL server
  • The range selection is OS specific
  • These ports are visible in a packet trace between an AIQUM or SnapMirror and a cluster
