  • Patent number: 9948495
    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.

  • Patent number: 8780899
    Abstract: A system and method for distributing data across a network including a plurality of trunked port lines, including modifying an existing field within one layer of a data packet on the basis of information found within another layer of the data packet and restricting the process of trunking distribution to only consider the modified layer. In an exemplary embodiment, a method and a system for improving packet data distribution across a communication network environment is provided that changes a field within the Layer 2 (L2) section of the packet on the basis of fields within the Layer 3 (L3) section of the packet. This may involve changing the destination Media Access Control (MAC) address on the basis of the destination IP address and limiting the trunk distribution determination to the L2 section of the packet data.
