3 Port and switch naming standards for CUP The configuration is saved to the initial program load (IPL) file. IPL is a more general term that refers to the process of loading an operating system into memory. The switch Active Configuration is replicated to the backup CP. This includes the port PDCM configuration, port block/unblock states, and port address names. If Active=Saved is enabled in the FMS Mode Register, then the Active Configuration is also replicated to the IPL file. If Brocade Advanced Zoning is in use, refer to the Fabric OS Administrator's Guide for more information on configuration. Port and switch naming standards for CUP Fabric OS handles differences in port and switch naming rules between CUP and itself as follows: • CUP employs 8-bit characters in port address names and switch names; Fabric OS employs 7-bit characters. When FMS mode is enabled, all characters greater than 0x40 and not equal to 0xFF (EBCIDC code page 037 [0x25], refer to Appendix B, "EBCDIC Code Page") are allowed in the name; therefore, it is possible for a channel to set a name with nonprintable characters. If a name contains nonprintable characters, they are displayed as dots (...). The following characters are also displayed as dots: semicolon (;), comma (,), equal sign (=), and at sign (@). NOTE Configuration files that contain nonprintable characters should not be edited manually because many editors replace nonprintable characters with some other characters without warning you first. • CUP has a 24-character unique port name limitation; Fabric OS supports port names up to 32 characters long. When FMS mode is enabled, names longer than 24 characters are truncated. FICON CUP commands Table 3 summarizes the Fabric OS CLI commands that can be used for managing FICON fabrics. For detailed information on these commands, see the Fabric OS Command Reference.
