Introduction to FICON and CUP

FICON is a protocol used between IBM (and compatible) mainframes and storage.

FICON Control Unit Port (CUP) is a protocol for managing FICON directors. CUP is used by IBM

mainframe management applications to provide in-band management for ESCON and FICON. CUP

is an optional, license-based feature.

Host-based management programs manage the switches using CUP protocol by sending

commands to the emulated Control Device implemented by Fabric OS. A Brocade switch or director

that supports CUP can be controlled by one or more host-based management programs or director

consoles, such as Web Tools or Fabric Manager. The director allows control to be shared between

host-based management programs and director consoles.

To monitor a FICON CUP environment in Fabric Manager, you must have the following (all can be

performed through Web Tools):

• A CUP license installed on a FICON director

• FICON Management Server (FMS) mode enabled on the FICON director

• CUP attributes (FMS Parameters) configured for the FICON director

The following FICON Emulation features can be configured in Fabric Manager in the FCIP Tunnel

Configuration wizard:

• FICON XRC Emulation

• FICON Tape Write Emulation

• FICON Tape Read Emulation
