Base Chassis MAC Address as Unique Identifier

The switch chassis requires a unique identifier in order to be recognized by other devices in the network.
The base chassis MAC address, which is automatically allocated by the switch, serves as this identifier.
The base chassis MAC address is always the start MAC address listed in the switch's default
MAC range 1.
Viewing the Base Chassis MAC Address
To display the switch's base chassis MAC address, use the
default MAC range 1. Be sure to specify the MAC range number ( 1 ), as shown below:
-> show mac-range 1
The following information displays:
Mac
Range Row Status
-----+----------------+--------+------------------+------------------
01 ACTIVE
Because MAC address 00:d0:95:6a:79:6e is the first address in default MAC range 1, it is automatically
allocated as the base chassis MAC address and, therefore, serves as a unique identifier for the switch as a
whole.

Determining Current MAC Address Allocation on the Switch

To quickly view all allocated MAC addresses, use the show mac-range alloc command. For example:
-> show mac-range
Mac
Range Row Status
-----+----------------+--------+------------------+------------------
01 ACTIVE
03 ACTIVE

Base Chassis MAC Address in Stacked Configurations

In stacked configurations of two or more OmniSwitch 6600 Family switches, the base MAC address for
the stack (also referred to as the virtual chassis) is always provided by the primary switch.
If a failover occurs and another switch assumes the primary role, the stack's base MAC address changes to
the address provided by the new primary switch.
For detailed information on stacked configurations, refer to
Family Stacks."
