Planning Considerations for Fibre Channel Topologies
9. Update channel path and control unit definitions — A cascaded FICON

control unit and an entry switch.
10. Verify FICON devices log back in — Inspect the Node List View
11. Verify cascaded FICON operation — Verify operation of established

b. Ensure that the Enable Switch Binding check box is checked (enabled).
c. Select the Restrict E_Ports radio button to restrict connections from
specific fabric elements to E_Ports. WWNs can be added to the
membership list to allow fabric element connection and removed from the
list to prohibit fabric element connection. Devices are allowed to connect
to any F_Port or FL_Port without restriction.
d. Click Activate to close the dialog box and enforce the connection policy.
environment requires channel entry switch and link address updates to the
input/output configuration program (IOCP) as follows:
a. In the IOCP, define an entry switch ID in the SWITCH keyword of the
channel path identifier (CHPID) definition.
An entry switch is a fabric director or switch connected to the FICON channel
b. In the IOCP, define a 2-byte link address (consisting of a switch (or
domain) address and port address) for the cascaded switch in the LINK
keyword of the control unit (CNTLUNIT) definition.
An cascaded switch is a fabric director or switch connected to a destination
c. Run the IOCP to create an input/output configuration data
set (IOCDS). The switch ID (CHPID macroinstructions) and 2-byte link
address (control unit macroinstructions) are updated in the IOCDS.
Refer to the IBM FICON Native Implementation and Reference Guide
(SG24-6266) for additional information.
