FICON Configuration
Fibre Connection (FICON) interface capabilities enhance the Cisco MDS 9000 Family by supporting
both open systems and mainframe storage network environments. Inclusion of Control Unit Port (CUP)
support further enhances the MDS offering by allowing in-band management of the switch from FICON
processors.
The fabric binding feature helps prevent unauthorized switches from joining the fabric or disrupting
current fabric operations. The Registered Link Incident Report (RLIR) application provides a method
for a switchport to send a LIR to a registered Nx-port.
Note FICON features can be implemented in any switch in the Cisco MDS 9000 Family running Cisco MDS
SAN-OS Release 1.3(x) or earlier. While no hardware changes are required, you do need the
MAINFRAME_PKG license to configure FICON parameters (see Chapter 9, “Obtaining and Installing
Licenses”).
