Chapter 36 Configuring FICON FICON Port Numbering Send documentation comments to [email protected] Figure 36-3 Default FICON Port Number in Numbering on the Cisco MDS 9000 Family Switch Module 1 16-Port module 0 1 2 3 4 5 6 7 8 9 10 11 11 13 14 15 Module 2 16-Port module 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 105217 The default FICON port number is assigned based on the front panel location of the port and is specific to the slot in which the module resides. Thirty-two (32) port numbers are assigned to each slot on all Cisco MDS 9000 Family switches except for the Cisco MDS 9513 Director, which has 16 port numbers assigned for each slot. These default numbers are assigned regardless of the module's physical presence in the chassis, the port status (up or down), or the number of ports on the module (4, 12, 16, 24, or 48). If a module has fewer ports than the number of port numbers assigned to the slot, then the excess port numbers are unused. If a module has more ports than the number of port numbers assigned to the slot, the excess ports cannot be used for FICON traffic unless you manually assign the port numbers. Note Follow the steps in "Assigning FICON Port Numbers to Slots" section on page 36-13 to make use of excess ports by manually assigning more port numbers to the slot. Before doing this, however, we recommend that you review the default port number assignments for Cisco MDS 9000 switches shown in Table 36-3 on page 36-42, and that you read the following sections to gain a complete understanding of FICON port numbering: "About the Reserved FICON Port Numbering Scheme" section on page 36-11, "FICON Port Numbering Guidelines" section on page 36-12, and "Assigning FICON Port Numbers to Slots" section on page 36-13. Note Only Fibre Channel, PortChannel, and FCIP ports are mapped to FICON port numbers. Other types of interfaces do not have a corresponding port number. Table 36-3 lists the default port number assignment for the Cisco MDS 9000 Family of switches and directors.
