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.
