saved.
MAC_Address
Specifies the beginning address of a block of 256 MAC addresses that are used for virtual MAC addressing.
Usage
Use this command to disregard the MAC addresses assigned and stored in card firmware and assign MAC
addresses for all Ethernet ports from the specified block of virtual MAC addresses. This command does not
affect the MAC addresses on SPIO cards.
There are 65536 MAC addresses (00:05:47:FF:00:00 - 00:05:47:FF:FF:FF) reserved for use by customers.
This range allows for the creation of 256 address blocks each containing 256 MAC addresses (for example,
00:05:47:FF:00:00, 00:05:47:FF:01:00, 00:05:47:FF:02:00, 00:05:47:FF:03:00, 00:05:47:FF:04:00, etc.).

Caution:
This configuration requires the configuration of a valid block of unique MAC addresses that are not
used anywhere else. Use of non-unique MAC addresses can degrade and impair the operation of your network.
Important:
This command is not supported on all platforms.
