Allow / Prohibit Matrix configuration
17
When initially installed, a switch allows any port to dynamically communicate with any other port.
Two connectivity attributes are defined to restrict this any-to-any capability for external ports: Block
and Prohibit.
Block is a port connectivity attribute that prevents all communication through a port. Prohibit is the
port connectivity attribute that prohibits or allows dynamic communication between ports when a
port is not blocked. Each port has a vector specifying its Prohibit attribute with respect to each of
the other ports in the switch. This attribute is always set symmetrically in that a pair of ports is
either prohibited or allowed to communicate dynamically.
The Port Connectivity table (shown in Figure 43 on page 223) displays the Port number (in
physical-location format), Port Name (port address name), Block attribute, Prohibit attribute, and
Area Id (port address, displayed in hexadecimal) in fixed columns. The right side is a port matrix,
that lists all ports by Area ID and identifies prohibited ports. Those columns are scrollable and
swappable.
Viewing Allow / Prohibit Matrix configurations
To display a list of Allow / Prohibit Matrix configurations, perform the following steps.
1. Select a FICON-enabled switch from the Fabric Tree.
2. Select Tasks > Manage > Switch Admin.
3. Click Show Advanced Mode to see all the available tabs and options.
4. Select the FICON CUP tab.
The FICON CUP page displays the FICON Management Server page in front. All attributes on
this page are read-only until FMS mode is enabled.
5. Click the Allow / Prohibit Matrix subtab.
Modifying Allow / Prohibit Matrix configurations
In the Allow / Prohibit Matrix Configuration dialog box, swapped ports are indicated with the
“(Swapped)” label (Figure 42).
