Managing Advanced Features


Cisco MDS 9000 Family switches support advanced features, such as world wide names, domains, and name server. The Fabric Manager allows you to configure these features on multiple Cisco 9000 switches. The Device Manager allows you to configure these advanced features on a single Cisco 9000 switch. This chapter describes how to configure these advanced features using the Fabric Manager and Device Manager.


Note For information about these advanced features and configuring them using the command-line interface (CLI), refer to the Cisco 9000 Family Configuration Guide.


This chapter includes the following information:

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 from the Fabric Manager, choose FC > WWN Manager on the menu tree. The dialog box from the Fabric Manager displays WWN information for multiple switches. To add WWNs from the Device Manager, choose WWN Manager from the FC menu. The dialog box from the Device Manager displays WWNs for a single switch.

Both dialog boxes show the display-only information described in Table 11-1.
