6.6 Virtual Address attributes 361
Virtual address attributes include the following attributes: 362
• VirtMacAddr 363
• VirtIscsiMacAddr 364
• VirtFIPMacAddr 365
• VirtWWN 366
• VirtWWPN 367
The default values of these virtual attributes is equal to the permanent addresses programmed onto the 368
controller. For example, the VirtMacAddr default value is MacAddr on that port or partition. 369
Note that the configuration of the above attributes depends on the DCIM_LCEnumeration 370
VirtualAddressManagement attribute described in the LC Management Profile, section 7.2.3. The 371
VirtualAddressManagement attribute needs to have “Console” value in order for the above attributes be 372
configurable. 373
To set these attributes, see Section 8.1 and 8.2 for more details. Virtual address attributes behave 374
differently from the other attributes in the following way: 375
6.6.1 Read Write behavior 376
The virtual address attributes listed above behave as Read-Only attributes if accessed via the System 377
Settings (F2 during POST)  Device Settings menu. However, they behave as Read-Write attributes 378
through the Lifecycle Controller Remote Services interface used by WSMAN clients. This allows a remote 379
application to change the virtual identities of NIC/CNA controllers, similar to the FlexAddress feature that 380
allows a chassis management controller (CMC) to distribute a predefined list of identities across all blade 381
NIC/CNA controllers on a chassis. 382
6.6.2 Reset behavior 383
Setting a particular Input/Ouput (IO) attribute to zeros causes that particular address to be erased and 384
reset to the default permanent address. The attributes can be set to default permanent values: as 385
equivalent to resetting to factory default and removing a virtual address attribute from a system. 386
When there is AC Power loss to the system, all the virtual address attributes are erased and reset to 387
default addresses when AC Power is restored to the system. AC Power loss includes power loss to both 388
MAIN and AUX power bus. 389
NOTE: This behavior may not be available on the Broadcom CNA. 390
6.7 Behavior Differences between Broadcom and QLogic CNAs 391
There are few key differences between CNA manufacturers: Broadcom and QLogic. The supported CNAs 392
for Broadcom and QLogic include: 393
Broadcom: 394
M710HD Dual Port 10Gig 57712 NDC, 395
QLogic: 396
Qlogic QMD8252-K Dual Port 10GbE NDC 397
398
Table 6 – Behavior Differences between Broadcom and QLogic CNAs lists the behaviorial differences. 399

Offload
personalities
Only two Offload personalities (FCoEOffloadMode and
iScsiOffloadMode) are allowed per port.
Partition 3 allows
iScsiOffloadMode personality and
Partition 4 allows
FCoEOffloadMode personality.
