Configuration Examples for Adding and Deleting OUIs

Example: Adding and Deleting OUIs

switch# configure terminal
switch(config)# wwn oui 0x10001c
switch(config)# no wwn oui 0x10001c
switch(config)# end

Example: Displaying OUIs

switch# show wwn oui

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
25: Standardized NAA WWN Formats , on page

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

Displaying WWN Information

Use the show wwn commands to display the status of the WWN configuration. See the following examples:
