Protection Mode

Protection Mode is a state where the device is operational but has implemented defenses against disruptive changes that could take the product out of service.

Implicit Protection Mode

1756-RM3 redundancy modules enter Implicit Protection Mode when the redundant chassis pair is synchronized. Implicit Protection Mode helps prevent configuration changes that can affect system behavior and cause unintended and unforeseen changes.
In Implicit Protection Mode, the device deactivates services that could disrupt the operation of the device, but the device continues to function. For example, configuration operations or firmware updates are disabled so that they do not impact the operation of the device.

Restrictions in Implicit Protection Mode

When the redundancy module is in implicit Protection Mode, the mode prevents the following actions:
  • Disable or re-enable fiber security
  • Disable or re-enable SFP fiber ports
  • Update the module firmware
  • Perform any module resets, remote or out-of-the-box
