saved.
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 the IDEEPROM on Ethernet Line
Cards and assign MAC addresses for all ports on all Ethernet Line Cards 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 (e.g.
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.
Example
To enable virtual MAC addressing for Ethernet ports on all Ethernet line cards in the system using a block of MAC
addresses starting at 00:05:47:FF:00:00, enter the following command:
