Multiple media access control (MAC) addresses
First Claim
Patent Images
1. A system comprising:
- a slave device communicatively connected to a master device in the system,the slave device including;
a first storage device that stores a real media access control (MAC) address of the slave device,the real MAC address of the slave device mapping to a real Internet protocol (IP) address associated with the slave device, anda second storage device that stores a virtual MAC address that is different from the real MAC address of the slave device,the second storage device being different from the first storage device, andthe virtual MAC address mapping to a real IP address associated with the master device and a virtual IP address associated with the master device, andwhen a failure is associated with the master device, the slave device is to;
receive the virtual MAC address from the master device,store the virtual MAC address in the second storage device,receive and process information, intended for the master device, based on the virtual MAC address, andreceive administrative services based on the real MAC address of the slave device.

Abstract
A method for providing multiple media access control (MAC) addresses in a device of a master/slave system may include providing a first MAC address in a MAC address storage of the device. The method may also include providing a second MAC address in a multicast table entry of a multicast hash filter of the device.

9. A method comprising:
-
storing, in a first storage device of a slave device, a real media access control (MAC) address of the slave device, the real MAC address of the slave device mapping to a real Internet protocol (IP) address associated with the slave device; receiving, by the slave device, a virtual MAC Address from a master device, the virtual MAC address mapping to a real IP address associated with the master device and a virtual IP address associated with the master device; storing, in a second storage device of the slave device, the virtual MAC address, the second storage device being different from the first storage device; using, by the slave device, the real MAC address of the slave device to access administrative services when a failure is associated with the master device; and using, by the slave device, the virtual MAC address to process traffic, intended for the master device, when the failure is associated with the master device. - View Dependent Claims (10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium storing instructions, the instructions comprising:
-
one or more instructions that, when executed by at least one processor of a slave device, cause the at least one processor to; store a real media access control (MAC) address of the slave device in a first storage component of the slave device, the real MAC address of the slave device mapping to a real Internet protocol (IP) address associated with the slave device; receive a virtual media access control (MAC) address from a master device, the virtual MAC address mapping to a real IP address associated with the master device and a virtual IP address associated with the master device; store the virtual MAC address in a second storage component of the slave device, the second storage component being different from the first storage component; use the real MAC address of the slave device to access administrative services; and use the virtual MAC address to process data, intended for the master device, after a failure of the master device. - View Dependent Claims (16, 17, 18, 19, 20)
