Managing MAC Addresses on the Switch

OmniSwitch 6600 Family Hardware Users Guide

page 2-71

Your OmniSwitch 6600 Family switch is shipped with thirty-two factory-installed MAC addresses. These 
MAC addresses, which are stored on an EEPROM card in the chassis, are used by the switch as unique 
identifiers for the following functions:

• Base chassis MAC address

• 802.1X authentication

• VLAN router ports

Similar to IP addresses, MAC addresses are assigned by the Internet Assigned Numbers Authority (IANA) 
and distributed to users in sequential blocks. A sequential block of MAC addresses is referred to as a 
MAC address range.

The switch’s EEPROM contains two factory-installed MAC address ranges:

• You cannot edit or delete MAC range 1 or MAC range 3 at any time.

• The factory-installed 32 MAC addresses are sufficient for most network configurations. However, if 

you require additional MAC addresses for your network, you may purchase additional MAC addresses 
from Alcatel. Contact your Alcatel representative for more information.

MAC Range 1

Reserved for the first two MAC addresses in the factory installed range of 32 
MAC addresses. The first—or start—MAC address in this range is always 
allocated as the base chassis MAC address. The second MAC address is 
allocated for 802.1X authentication. 

MAC Range 3

Contains MAC addresses used for each port in the system.
