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:
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.
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 a MAC exclusion range.
5. Click Delete. You are prompted to confirm your choice.
6. Click OK.
IMPORTANT:
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 profile contains one or more MAC addresses associated with it, VCEM
identifies these addresses as external. Addresses identified as external are reserved for VC Domains outside
of VCEM and will not be used by VCEM.
To change the status of an address from External to Free, use the Reclaim External button. Before freeing an
address, verify that the address is no longer used by a VC Domain outside of VCEM.
To reclaim MAC addresses:
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.
4. Select the Individual addresses tab.
68 Managing MAC and WWN addresses
External addresses that are included in a MAC exclusion range remain external addresses.
If the exclusion range includes external addresses, these external addresses remain external,
