World Wide Names
The world wide name (WWN) in the switch is equivalent to the Ethernet MAC address. As with the MAC
address, you must uniquely associate the WWN to a single device. The principal switch selection and the
allocation of domain IDs rely on the WWN. The WWN manager, a process-level manager residing on the
switch’s supervisor module, assigns WWNs to each switch.
Cisco MDS 9000 Family switches support three network address authority (NAA) address formats (see Table
25: Standardized NAA WWN Formats , on page 305).
Table 25: Standardized NAA WWN Formats

Changes to the world-wide names should be made by an administrator or individual who is completely familiar
with switch operations.
