It is recommended that you store the configuration file locally, and validate the
new configuration. It is also important to store the configuration file in a safe
location because this is your original copy of the OFM configuration. If an AMM
has a hardware failure and you don't have a standby AMM, then this is your
single source to reproduce the OFM configuration.
If you wish to apply the configuration directly or to create a Requirements Report,
you can do it directly from this page.

address. You can select ranges that meet the type of adapter that you are using.
Each vendor has allocated a special range for OFM outside of their normal range
which guarantees that these addresses do not conflict with any previous or
future burned-in addresses. Selecting a vendor automatically sets values within
that range. You can also set it to user defined mode and select any range by
editing the From and To fields.
The default address ranges are as follows:
Emulex:
WWNN - use 2F:FE:00:00:C9:XX:XX:XX and 2F:FF:00:00:C9:XX:XX:XX for the two ports.
WWPN - use 2F:FC:00:00:C9:XX:XX:XX and 2F:FD:00:00:C9:XX:XX:XX for the two ports.
QLogic:
21:80:00:E0:8B:0X:XX:XX for the first port and 21:81:00:E0:8B:2X:XX:XX for the
second port (the WWPN is generated automatically from the WWNN).
The range for the Ethernet addresses is: 00:1A:64:76:00:00 - 00:1A:64:76:FF:FF.
default is that the system assigns an address from one of the ranges for each
port of the device. When generating the file automatically, the system allocates
the addresses for the even ports out of the first range and allocates the addresses
for the odd ports out of the second range.
Note: For some devices this might not be the appropriate allocation. For
example, a Fibre Channel high speed adapter is connected to ports 6 and
8, which are both allocated out of the second range, and this might
appear as two different devices rather then a single device. You can

each of the ports 1 to 8, and FC addresses will be assigned for each of the ports
from 3 to 8. These configurations match a single slot blade. These are generic
