Controllers with network security applied are not responding to a ping command after firmware upgrade

Issue

NC2 and ACX57xx controllers with network security applied will no longer respond to a ping command after upgrading to newest firmware.

Product Line

Andover Continuum

Environment

  • Network Security
  • ACX5740
  • ACX5720
  • NC2
  • CX9680

Cause

The ping command was used to monitor controllers offline/online status. 

CX9680 and ACX57xx controllers (with network security applied) stopped responding to  a ping command after respective firmware versions  v2.100048 and v1.100052 were applied.

Resolution

This is functioning as designed due to the hardening of the controller's firmware for security reasons when network security has been applied.
