# Locally Administered Address (LAA)

The Locally Administered Address feature allows you to override a device’s MAC Address and assign an address of your choice. The address is a 12-digit hexadecimal number in the range: 0000 0000 0001 – FEFF FFFF FFFF.

| CAUTION: Make sure no other systems on the network use this address.

Notes

- Do not use a multicast address (least significant bit of the high byte = 1).
  For example, in the address 0y123456789A, "y" cannot be an odd number. (y must be 0, 2, 4, 6, 8, A, C, or E.)
- To restore the default MAC address, click Use Default.
- You cannot change the address if the adapter is part of a team.
- Changing this setting may cause a momentary loss of connectivity.

The LAA setting is disabled and cannot be changed because one or more of the following is true:

- The device is configured to iSCSI boot primary or secondary.
- The device or team is bound to the Microsoft Virtual Switch Protocol.
