Excluded Addresses
Creating MAC exclusion ranges
VCEM requires that you define exclusion ranges for both MAC and WWN address ranges that
are in use by VC Domains outside VCEM management. Exclusion ranges are used to set aside
addresses that might be in use for other purposes within your data center. Excluded address ranges
are not assigned for use by VCEM.
1. From the VCEM home page, under the Administration heading, click the MAC addresses
hyperlink.
2. From the Select ranges to configure list, select MAC.
3. Select a MAC address range. The exclusion range must be contained within the address range
to which the exclusion range belongs.
4. Select the Exclusion ranges tab.
5. To create the exclusion range, click New.
IMPORTANT: External addresses that are included in a MAC exclusion range remain external
addresses. The status of an external address does not change if it is included in a MAC
exclusion range.
6. Select a HP-predefined address range, or manually enter the address range to exclude.
Deleting MAC exclusion ranges
1. From the VCEM home page, under the Administration heading, click the MAC addresses
hyperlink.

3. Select a MAC address range. The exclusion range must be contained within the address range
to which the exclusion range belongs.
4. Select a MAC exclusion range.
5. Click Delete. You are prompted to confirm your choice.
6. Click OK.
IMPORTANT: If the exclusion range includes external addresses, these external addresses remain
external, even if the exclusion range is removed.
To avoid conflicts, make sure all addresses within this range are not being used by any other
Ethernet device on your network.
Reclaiming external MAC addresses
External MAC addresses are generated when a VC Domain containing server profiles is removed
from a VC Domain Group. Since every server profile contains one or more MAC addresses
