RHEL6 / RHEL7: After an NFS client's TCP connection goes idle, does it reconnect using the same source port or a different port?

Solution Verified - Updated -

Issue

  • I've noticed the Linux NFS client using TCP may drop a connection due to an NFS mount not being accessed for a while (5 minute idle timer), or if certain errors occur on NFSv4 mounts. When it becomes active again and the TCP connection is re-established, will the NFS client re-use the same source TCP port or a different one?

Environment

  • Red Hat Enterprise Linux 6 or 7 (NFS client)
  • NFS (v3 or v4)
