Performing Advanced Configuration Tasks Showing PID assignments Use the following procedure to display PID assignments. 1. Connect to the switch and log in using an account with admin permissions. 2. Based on what you want to display, enter the appropriate command. ∙ To display the assigned WWN-PID bindings, enter the following: wwnAddress --show ∙ To display the PID assigned to the specific device WWN, enter the following: wwnAddress -findPID wwn Ports Ports provide either a physical or virtual network connection point for a device. Brocade devices support a wide variety of ports. Port Types The following is a list of port types that may be part of a Brocade device: ∙ D_Port -- A diagnostic port lets an administrator isolate the link to diagnose link-level faults. This port runs only specific diagnostics tests and does not carry any fabric traffic. Refer to Diagnostic Port on page 415 for more information on this port type. ∙ E_Port -- An expansion port that is assigned to ISL links to expand a fabric by connecting it to other switches. Two connected E_Ports form an inter-switch link (ISL). When E_Ports are used to connect switches, those switches merge into a single fabric without an isolation demarcation point. ISLs are non-routed links. ∙ EX_Port -- A type of E_Port that connects a Fibre Channel router to an edge fabric. From the point of view of a switch in an edge fabric, an EX_Port appears as a normal E_Port. It follows applicable Fibre Channel standards as other E_Ports. However, the router terminates EX_Ports rather than allowing different fabrics to merge as would happen on a switch with regular E_Ports. An EX_Port cannot be connected to another EX_Port. ∙ F_Port -- A fabric port that is assigned to fabric-capable devices, such as SAN storage devices. ∙ G_Port -- A generic port that acts as a transition port for non-loop fabric-capable devices. ∙ L_Port or FL_Port -- A loop or fabric loop port that connects loop devices. L_Ports are associated with private loop devices and FL_Ports are associated with public loop devices. ∙ U_Port -- A universal Fibre Channel port. This is the base Fibre Channel port type, and all unidentified or uninitiated ports are listed as U_Ports. ∙ VE_Port -- A virtual E_Port that is a gigabit Ethernet switch port configured for an FCIP tunnel. ∙ VEX_Port -- A virtual EX_Port that connects a Fibre Channel router to an edge fabric. From the point of view of a switch in an edge fabric, a VEX_Port appears as a normal VE_Port. It follows the same Fibre Channel protocol as other VE_Ports. However, the router terminates VEX_Ports rather than allowing different fabrics to merge as would happen on a switch with regular VE_Ports. Director port blades Because DCX 8510 and X6 Directors 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 Backbones identify ports by slot/port notation Brocade Fabric OS Administration Guide, 8.0.1 53-1004111-02 73
