Control Unit Port (CUP) overview

Control Unit Port (CUP) is an interface defined by IBM that defines the Channel Command Words
that the FICON host can use for managing the switch. The protocol used is the IBM version of the
ANSI FC-SB3 single-byte command code specification, which defines the protocol used for
transporting CCWs to the switch, and for the switch to direct data and status back.CUP is an
optional licensed feature.
CUP allows for inband management and for the FICON director performance metrics using the RMF
74-7 record, more commonly known as the FICON Director Activity Report. Host-based
management programs manage the FICON directors and switches using CUP protocol by sending
commands to the emulated control device defined in HCD (Hardware Configuration Definition). A
FICON director or switch that supports CUP can be controlled by one or more host-based
management programs or director consoles. Control of the FICON directors can be shared between
these options. There are 39 CUP commands, or CCWs, for monitor and control of the FICON director
functions. CUP commands are oriented towards management of a single switch, even though the
use of CUP in a cascaded FICON environment is fully supported.
NOTE
The CUP port address will always be xxFExx. Port Addresses xxFExx and xxFFxx are unavailable to
assign to physical ports when FMS is enabled.
