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.

24. A system comprising:
-
a master device; a slave device communicatively connected to master device, the slave device including a media access control (MAC) address storage device that stores a real MAC address of the slave device; and a programmable multicast hash filter, associated with the system, that is programmed to store a virtual MAC address, which is received from the master device, as an entry in a table of the programmable multicast hash filter, where the slave device is to use both the real MAC address and the virtual MAC address during a time interval when the slave device assumes the role of the master device. - View Dependent Claims (25, 26, 27, 28, 29, 30)

31. A method for providing multiple media access control (MAC) addresses for a device of a master/slave system, the method comprising:
-
providing, in a MAC address storage of the device, a first MAC address that identifies the device to the master/slave system; programming a multicast table entry, of a multicast hash filter, of the master/slave system, with a second MAC address, where the second MAC address identifies the device to the master/slave system and permits the device to act as a master device of the master/slave system; using the first MAC address to continue to access administrative services of the master/slave system during a time interval when the device acts as the master device; and using the second MAC address to route messages during the time interval when the device acts as the master device. - View Dependent Claims (32, 33, 34, 35, 36, 37)

38. A master/slave system, including a slave device connected to a master device, the master/slave system comprising:
-
a programmable multicast hash filter that is programmed to store a virtual media access control (MAC) address of the master device, as a first entry in a table of the programmable multicast hash filter, and is programmed to store a real MAC address of the slave device, as a second entry in the table of the programmable multicast hash filter, where the slave device is to use both the real MAC address and the virtual MAC address upon a failure of the master device. - View Dependent Claims (39, 40, 41, 42, 43)
