The tool is pretty simple, but offers a time saving way of ensuing all your MAC addresses are formatted the same, prior to using them for a CSV import.Ĭisco Prime is slowly being replaced by Cisco DNA Center, but is a key use case for the MAC convertor tool.

Is that if the physical hardware changes, so does the IPv6 address. The firstĦ4 bits of the device's address are supplied using the Or in IPv6 colon hexadecimal notation, 3BA7:94FF:FE07:CBD0. The identifier thus becomes ∳B-A7-94-FF-FE-07-CB-D0, To one, which changes the first octet from ∳9 to ∳B. The local portion of ∰7-CB-D0 becomes the This can then be combined with a network prefix (routing prefix and subnet ID) to determine a corresponding IPv6 address for the device.Īddress of 39-A7-94-07-CB-D0 (illustrated in Figure 98 ):įigure 98: Converting IEEE 802 MAC Addresses To IPv6 Modified EUI-64 IdentifiersĢ4 bits of the identifier, and put it into the first (leftmost) 24 bits A simple process can be used to determine the interface identifier from the 48-bit MAC address of a device like an Ethernet network interface card.

Key Concept: The last 64 bits of IPv6 unicast addresses are used for interface identifiers, which are created in a special format called modified EUI-64. This gives us the modified EUI-64 interface ID. We change the universal/local bit (bit 7 from the left)įrom a zero to a one. We take the 24-bit local portion (the right-mostĢ4 bits of the Ethernet address) and put it into the right-most 24 bits Left-most 24 bits of the Ethernet address, and put them into the left-mostĢ4 bits of the interface ID. These can be converted to EUI-64Īnd then to modified EUI-64 form for creating an IPv6 interface ID.
