2. Enter the wwnAddress -unbind command to clear the PID binding for the specified WWN.

Showing PID assignments

1. Connect to the switch and log in using an account assigned to the admin role.
2. Based on what you want to display, enter the appropriate command:
•wwnAddress –show displays the assigned WWN-PID bindings.
•wwnAddress –findPID wwn displays the PID assigned to the device WWN specified.

Ports

Because enterprise-class platforms contain interchangeable port blades, their procedures differ
from those for fixed-port switches. For example, fixed-port models identify ports only by the port
number, while enterprise-class platforms identify ports by slot/port notation.
NOTE
For detailed information about the Brocade 48000 director, and the Brocade DCX and DCX-4S
enterprise-class platforms, see the Brocade 48000 Hardware Reference Manual, the Brocade DCX
Data Center Backbone Hardware Reference Manual, and the Brocade DCX-4S Data Center
Backbone Hardware Reference Manual, respectively.
The different blades that can be inserted into a chassis are described as follows:
•Control processor blades (CPs) contain communication ports for system management, and are
used for low-level, platform-wide tasks. In the Brocade 48000, CPs are used for intra-platform
switching.
•Core blades in the Brocade DCX (CORE8) and DCX-4S (CR4S-8) are used for intra-chassis
switching as well as interconnecting two Brocade DCX enterprise-class platforms.
•Port blades are used for host, storage, and interswitch connections.
•AP blades are used for Fibre Channel Application Services and Routing Services, iSCSI
bridging, FCIP, Converged Enhanced Ethernet, storage virtualization, and encryption support.
NOTE
On each port blade, a particular port must be represented by both slot number and port number.
The Brocade 48000 has 10 slots that contain control processor, port, and application (AP) blades:
•Slot numbers 5 and 6 contain control processor blades.
•Slot numbers 1 through 4 and 7 through 10 contain port and AP blades.
The Brocade DCX has 12 slots that contain control processor, core, port, and AP blades:
•Slot numbers 6 and 7 contain CPs.
•Slot numbers 5 and 8 contain core blades.
•Slot numbers 1 through 4 and 9 through 12 contain port and AP blades.
