7 Managing MAC and WWN addresses

MAC Addresses

NOTE: A "VCEM-defined” range has been reserved, from which VCEM allocates MAC addresses.

VCEM no longer uses the “HP Pre-defined” range for MAC address allocation. However, server

profiles created before VCEM 1.40 will continue to use the HP Pre-defined addresses already

assigned to them.

When using VCEM-assigned MAC addresses, you can choose between VCEM-defined MAC

address ranges or user-defined MAC address ranges. You can use the HP predefined MAC address

range only to import server profiles or server profiles created on previous versions of VCEM.

• VCEM-defined MAC address ranges—HP recommends this range. This predefined range is

reserved and never appears as factory-default on any hardware. There are 131,072 unique

addresses from which VCEM automatically assigns to server profiles on demand.

• User-defined MAC address range—To prevent potential conflict with other hardware MAC

addresses in the environment, you can use a subrange of MAC addresses reserved by the

IEEE for locally administered MAC addresses. Ensure that the range does not conflict with any

Ethernet device already deployed within the enterprise.

To access the MAC addresses from the VCEM home page, click the MAC addresses hyperlink.

The MAC Ranges List page appears.

Tracking individual MAC addresses

Individual addresses in a MAC range (HP-predefined, VCEM-defined, or user-defined) can be

monitored by clicking the Individual addresses secondary tab within the MAC Ranges List page.
