Abstract
In a first aspect, a first method is provided for creating a media access control (MAC) address for a device. The first method includes the steps of (1) obtaining one or more identifiers; (2) obtaining a first MAC address; and (3) creating at least a second MAC address based on the one or more identifiers and the first MAC address. Numerous other aspects are provided.
Claims10
An apparatus for creating a media access control (MAC) address for a first device, comprising:
- a management tool configured to couple to an Ethernet adapter and a partition, and configured to:
- obtain one or more identifiers;
- obtain a first MAC address;
- and
- create at least a second MAC address based on the one or more identifiers and the first MAC address;
- and
- a hosting partition coupled to the management tool, and configured to employ the second MAC address,
- wherein the management tool is further configured to create a second and a third MAC address based on the one or more identifiers and the first MAC address;
- and
- wherein the hosting partition is further configured to:
- employ the second MAC address as an address of a hosted partition of the first device;
- and
- while employing the second MAC address as the address of the hosted partition:
- detect another device using the second address on the same portion of the network;
- employ the third MAC address as the address of the hosted partition of the first device;
- and
- update a table entry in the Ethernet adapter used by the first device from the second MAC address to the third MAC address.
An apparatus for creating a media access control (MAC) address for a first device, comprising:
- a management tool configured to couple to an Ethernet adapter and a partition, and configured to:
- obtain one or more identifiers;
- obtain a first MAC address;
- and
- create at least a second MAC address based on the one or more identifiers and the first MAC address,
- wherein the management tool is further configured to:
- receive a starting MAC address of a MAC address range;
- and
- create at least a second MAC address based on the one or more identifiers, the first MAC address and the starting MAC address of the MAC address range.
An apparatus for creating a media access control (MAC) address for a first device, comprising:
- a management tool configured to couple to an Ethernet adapter and a partition, and configured to:
- obtain one or more identifiers;
- obtain a first MAC address;
- and
- create at least a second MAC address based on the one or more identifiers and the first MAC address,
- a hosting partition coupled to the management tool, and configured to:
- determine whether the second MAC address is used by another device on a portion of a network to which the first device is coupled;
- and
- if the second MAC address is not used by another device on the portion of the network to which the first device is coupled, employ the second MAC address on the portion of the network.
