Duplicate Device Index setting
The FTE subsystem detects duplicate Device Index settings in separate nodes.
Diagnostic Check
All nodes will stop tracking cable status for the detected duplicate Device
Index value. Communications will continue and will not impact system
performance until there is a cable fault. This fault will also be detected by
the FTE System Management Tool.
A duplicate Device Index could cause a duplicate IP Address. In most
cases, the duplicate IP Address would be detected first and prevent the
FTE diagnostic messages from being sent.
Cause 1
Have set Device Index switches on separate IOTA's to same value.
