IPv6 addressing for initial connection

When you use IPv6 addressing, use the IPv6 link-local address to complete the initial connection to the CMM.

The link-local address is a unique IPv6 address for the CMM that is automatically generated according to its MAC address. It is of the form FE80::3BA7:94FF:FE07:CBD0.

Determine the link-local address of the CMM in any of the following ways:

If the CMM does not have a network access tag and you are unable to access the CMM by using IPv4, complete the following steps to calculate link-local address:

Complete the following steps:

  1. Write down the MAC address of the CMM. It is on a label on the CMM, near the reset button. The label reads MMxxxxxxxxxxxx, where xxxxxxxxxxxx is the MAC address. For example:

    39-A7-94-07-CB-D0

  2. Split the MAC address into two parts and insert FF-FE in the middle.
    For example:

    39-A7-94-FF-FE-07-CB-D0

  3. Convert the two hexadecimal digits at the left end of the string to binary.
    For example:
    • 39-A7-94-FF-FE-07-CB-D0
    • 00111001-A7-94-FF-FE-07-CB-D0
  4. Invert the value of bit 7 of the binary string.
    For example:
    • 00111001-A7-94-FF-FE-07-CB-D0
    • 00111011-A7-94-FF-FE-07-CB-D0
  5. Convert the binary digits at the left end of the string back to hexadecimal.
    For example:
    • 00111011-A7-94-FF-FE-07-CB-D0
    • 3B-A7-94-FF-FE-07-CB-D0
  6. Combine the hexadecimal digit pairs into 4-digit groups.
    For example:
    • 3B-A7-94-FF-FE-07-CB-D0
    • 3BA7-94FF-FE07-CBD0
  7. Replace dash (-) separators with colon (:) separators.
    For example:
    • 3BA7-94FF-FE07-CBD0
    • 3BA7:94FF:FE07:CBD0
  8. Add FE80:: to the left of the string.
    For example:

    FE80::3BA7:94FF:FE07:CBD0

For a MAC address of 39-A7-94-07-CB-D0, the link-local address that is used for initial IPv6 access is FE80::3BA7:94FF:FE07:CBD0.
