Description (partial)

In rare circumstances, fail-to-wire (FTW) Ethernet port module (EPMs) may flap when a show tech is collected from the device via the 'show tech fprm detail' command in the local-mgmt CLI.

This has been observed when the 'show tech fprm detail' command is issued in the local-mgmt CLI in the FXOS shell.  This likely only occurs when there are at least three FTW pairs in service (6 ports in total).

This issue is still under active investigation.
