When using IPv6 addressing, the only way to initially connect
to the advanced management module is by using the IPv6 link-local
address.
The link-local address is a
unique IPv6 address for the advanced management module that is automatically
generated based on its MAC address. It is of the form: FE80::3BA7:94FF:FE07:CBD0.
The
link-local address for the advanced management module can be determined
in one of the following ways:
- Some advanced management modules will list the link-local address
on a label that is attached to the advanced management module.
- If you are able to log in to the management module command-line
interface (CLI) using IPv4 addressing, the link-local address can
be viewed using the ifconfig command (see ifconfig command for
information).
- If you are able to log in to the management module web interface
using IPv4 addressing, the link-local address can be viewed in the
Primary Management Module, IPv6 section of the MM Control → Network
Interfaces page (see the BladeCenter Advanced Management Module
User's Guide for information).
If the advanced management module does not have a label listing
the link-local address and you are unable to access the advanced management
module using IPv4, complete the following steps to calculate link-local
address:
-
Write down the MAC address of the advanced management module.
It is on a label on the management module, below the IP reset button.
The label reads MMxxxxxxxxxxxx, where xxxxxxxxxxxx is
the MAC address. For example,
39-A7-94-07-CB-D0
-
Split the MAC address into two parts and insert
FF-FE in the middle. For example,
39-A7-94-FF-FE-07-CB-D0
-
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
-
Invert the value for bit 7 of the binary string. For example,
-
00111001-A7-94-FF-FE-07-CB-D0
-
00111011-A7-94-FF-FE-07-CB-D0
-
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
-
Combine the hexadecimal digit pairs into 4-digit
groups. For example,
-
3B-A7-94-FF-FE-07-CB-D0
-
3BA7-94FF-FE07-CBD0
-
Replace dash (-) separators with colon (:)
separators. For example,
-
3BA7-94FF-FE07-CBD0
-
3BA7:94FF:FE07:CBD0
-
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 used for initial IPv6 access is FE80::3BA7:94FF:FE07:CBD0.
