NOTE: By using the racresetcfg subcommand, you can reset the Flex Address of a CMC to its factory-default setting, which
is “disabled”. The RACADM syntax is:
racadm racresetcfg -c flex
For more information about the FlexAddress-related RACADM commands and data about the other factory-default properties,
see the
Chassis Management Controller for PowerEdge VRTX RACADM Command Line Reference Guide
available at dell.com/
cmcmanuals.
The server must be turned o before you begin conguration. You can enable or disable FlexAddress on a per-fabric–basis. Additionally, you
can enable or disable the feature on a per-slot–basis. After you enable the feature on a per-fabric–basis, you can select slots to be enabled.
For example, if Fabric-A is enabled, any slots that are enabled have FlexAddress enabled only on Fabric-A. All other fabrics use the factory-
assigned WWN/MAC on the server.
NOTE: FlexAddress does not take eect on a server module until the next reboot. When the FlexAddress feature is deployed for
the rst time on a given server module, it requires a power-down and power-up sequence for FlexAddress to take eect.
FlexAddress on Ethernet devices is programmed by the server module BIOS. For the server module BIOS to program the
address, it needs to be operational which requires the server module to be powered up. When the power-down and power-up
sequences complete, the chassis-assigned MAC addresses are available for Wake-On-LAN (WOL) function.
Conguring FlexAddress for Chassis-Level Fabric and Slots
At the chassis level, you can enable or disable the FlexAddress feature for fabrics and slots. FlexAddress is enabled on a per-fabric–basis
and then slots are selected for participation in the feature. Both fabrics and slots must be enabled to successfully congure FlexAddress.
Conguring FlexAddress for Chassis-Level Fabric and Slots Using CMC
Web Interface
If a server is present in the slot, turn it o before enabling the FlexAddress feature on that slot.
To enable or disable fabric and slots to use the FlexAddress feature using the CMC Web interface:
1 In the left pane, click Server Overview > Setup > FlexAddress..
2 On the Deploy FlexAddress page, in the Select Fabrics for Chassis-Assigned WWN/MACs section, select the fabric type (Fabric-A
or iDRAC) to which you want to enable FlexAddress. To disable, clear the option.
3 On the Select Slots for Chassis-Assigned WWN/MACs page, select the Enabled option for the slot to which you want to enable
FlexAddress. To disable, clear the option.
NOTE
: Note the following:
If a slot is not selected, FlexAddress is not enabled for the selected fabric.
When none of the fabrics are selected and a server slot is selected and applied, the following message is displayed No
fabrics selected! FlexAddress will not be used on this chassis. Select both the fabric and the slot
to successfully congure FlexAddress.
Conguring Flexaddress for slave slot is not allowed. The option is greyed out in the CMC Web interface. The Ethernet
devices associated with the slave slot of the server, inherits the master slot conguration.
