Managing World Wide Names

Each port on a Cisco MDS 9000 Family switch is uniquely identified by its world wide names (WWNs), which include the switch MAC address and an identifier for each port. The principal switch selection and the allocation of domain IDs use the WWN to identify a specific port.

To add WWNs, perform the following steps.

  1. From the Fabric Manager, choose FC > WWN Manager on the menu tree, OR From the Device Manager, choose WWN Manager from the FC menu.

    The information pane of the Fabric Manager displays WWN information for multiple switches. The dialog box from the Device Manager displays WWN information for a single switch.

  2. Configure the BaseMacAddress and MacAddressRange attributes for the WWN(s).
  3. In the Fabric Manager information pane, the information is updated. In the Device Manager dialog, click Apply to accept the changes; click Close to close the WWWN Manager dialog without saving changes.
