12.4.2 Server network configuration

Check the following points regarding the server network configuration in which JP1/IM is to be used:

• Media sense (in Windows)

  We recommend that you disable the Windows media sense functionality that detects LAN cable disconnection and inactivates IP addresses. If the media sense functionality is enabled, a temporary network error will cause IP addresses to be lost, disabling JP1 communication.

• Duplicate NIC

  Some OSs provide duplicate NIC functionality (for example, Windows NIC teaming or AIX Ethernet channel) for switching to a standby NIC if the primary NIC fails. A server running JP1 that uses the duplicate NIC functionality must be completely compatible with non-duplicate NIC operations and must not affect JP1 operations.
