Configuring an Allow/Prohibit Matrix
The Allow/Prohibit Matrix is a FICON port attribute that can be used to prohibit communication
between specific ports. Prohibits are not recommended on E_Ports (inter switch links).
The Allow/Prohibit Matrix can be manipulated by host-based management programs using FICON
CUP, or from a Management program to create policies and determine paths for data and
command flows. Up to 8 Allow/Prohibit matrices can be modified at the same time. Allow/Prohibit
Matrix settings apply per switch rather than per fabric, and only work when an active zone
configuration is present in the fabric.
Multiple configurations may be defined, edited, copied, or removed. Only one configuration may be
active per switch.
NOTE
If you receive a 'FICON not supported on switch' error, refer to FICON troubleshooting for a list of
possible causes.
1. Select Configure > Allow/Prohibit Matrix.
The Configure Allow/Prohibit Matrix dialog box displays.
2. Select a switch from Available Switches.
Two default configurations (Active and IPL) are displayed in a tree structure below the switch.
Existing configurations are also displayed.
3. Choose one of the following options:
• Double-click a configuration file.
• Select a configuration file and click the right arrow.
A matrix displays. The switch ports are displayed on both the vertical axis and horizontal
axis. A green circle icon ( ) indicates communication is allowed between the ports.
