FlexAddress The FlexAddress feature is an optional upgrade introduced in CMC 1.1 that allows server modules to replace the factory assigned World Wide Name and Media Access Control (WWN/MAC) network IDs with WWN/MAC IDs provided by the chassis. Every server module is assigned unique WWN and MAC IDs as part of the manufacturing process. Before the FlexAddress feature was introduced, if you had to replace one server module with another, the WWN/MAC IDs would change and Ethernet network management tools and SAN resources would need to be reconfigured to be aware of the new server module. FlexAddress allows the CMC to assign WWN/MAC IDs to a particular slot and override the factory IDs. If the server module is replaced, the slot-based WWN/MAC ID remains the same. This feature eliminates the need to reconfigure Ethernet network management tools and SAN resources for a new server module. Additionally, the override action only occurs when a server module is inserted in a FlexAddress enabled chassis; no permanent changes are made to the server module. If a server module is moved to a chassis that does not support FlexAddress, the factory assigned WWN/MAC IDs are used. Prior to installing FlexAddress, you can determine the range of MAC addresses contained on a FlexAddress feature card by inserting the SD card into an USB Memory Card Reader and viewing the file pwwn_mac.xml. This clear text XML file on the SD card contains an XML tag mac_start, which is the first starting hex MAC address that will be used for this unique MAC address range. The mac_count tag is the total number of MAC addresses that the SD card allocates. The total MAC range allocated can be determined by: + 0xCF (208 - 1) = mac_end Initial System Configuration 43

FlexAddress
The FlexAddress feature is an optional upgrade introduced in CMC 1.1 that
allows server modules to replace the factory assigned World Wide Name and
Media Access Control (WWN/MAC) network IDs with WWN/MAC IDs
provided by the chassis.
Every server module is assigned unique WWN and MAC IDs as part of the
manufacturing process. Before the FlexAddress feature was introduced, if you
had to replace one server module with another, the WWN/MAC IDs would
change and Ethernet network management tools and SAN resources would
need to be reconfigured to be aware of the new server module.
FlexAddress allows the CMC to assign WWN/MAC IDs to a particular slot
and
override
the factory IDs. If the server module is replaced, the slot-based
WWN/MAC ID remains the same. This feature eliminates the need to
reconfigure Ethernet network management tools and SAN resources for a new
server module.
Additionally, the
override
action only occurs when a server module is inserted
in a FlexAddress enabled chassis; no permanent changes are made to the
server module. If a server module is moved to a chassis that does not support
FlexAddress, the factory assigned WWN/MAC IDs are used.
Prior to installing FlexAddress, you can determine the range of MAC
addresses contained on a FlexAddress feature card by inserting the SD card
into an USB Memory Card Reader and viewing the file
pwwn_mac.xml
. This
clear text XML file on the SD card contains an XML tag
mac_start
, which is
the first starting hex MAC address that will be used for this unique MAC
address range. The
mac_count
tag is the total number of MAC addresses that
the SD card allocates. The total MAC range allocated can be determined by:
<
mac_start
> + 0xCF (208 - 1) = mac_end
