Managing MAC Addresses on the Switch

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:

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.

 

 

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.
