NOTE: FlexAddress does not take effect on a server module until the next reboot. When the
FlexAddress feature is deployed for the first time on a given server module, it requires a power-
down and power-up sequence for FlexAddress to take effect. 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.
Configuring 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 configure FlexAddress.
Configuring FlexAddress for Chassis-Level Fabric and Slots Using CMC Web Interface
If a server is present in the slot, turn it off 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 configure
FlexAddress.
• Configuring 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 configuration.
4. To save the settings, click Apply.
Configuring FlexAddress for Chassis-Level Fabric and Slots Using RACADM
To enable or disable fabrics, use the following RACADM command:
racadm setflexaddr [-f <fabricName> <state>]
where, <fabricName> = A or iDRAC and <state> = 0 or 1
0 is disable and 1 is enable.
To enable or disable slots, use the following RACADM command:
racadm setflexaddr [-i <slot#> <state>
where, <slot#> = 1 or 4 and <state> = 0 or 1
0 is disable and 1 is enable.
