Title: SAFE STATE FOR NETWORKED DEVICES
Abstract:
A method placing a device in safe state is disclosed. The method includes initiating a safe state for a device. In one embodiment, an operational functionality of the device is disabled. A safe state message at an interface of the device may be received. The interface may be designated as a management interface. Information may be received at the management interface, wherein the information manages the device. The method may also include disabling a non-management interface of the device, wherein the non-management interface is an interface that does not receive a safe state message. The method may further include shutting down a non-management interface of the device, wherein the non-management interface is an interface that does not receive a safe state message. A normal state for the device may be initiated, wherein in the normal state the device restores the operational functionality of the device.
