Managing MAC Addresses on the Switch

Your OmniSwitch 6600 series switch is shipped with thirty-two (32) 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:

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 the switch’s remaining unused MAC addresses (i.e., MAC addresses
	3 through 32).

MAC Range Guidelines

•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.
