Configuring CUP port connectivity
18
When creating a new configuration or editing an existing configuration, keep in mind that Web Tools
port name input is restricted to printable ASCII characters. Therefore, when Web Tools displays a
port name, if there are characters beyond printable ASCII characters (which would have been
created by the Host Program), those characters are displayed as dots (.).
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 102 on page 227) 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,
which lists all ports by Area ID and identifies prohibited ports. Those columns are scrollable and
swappable.
DISPLAYING CUP PORT CONNECTIVITY CONFIGURATIONS
Use the following procedure to display a list of CUP port connectivity configurations, as shown in
Figure 101 on page 226.
To display the CUP Port Connectivity Configurations list
1. Click a FICON-enabled switch from the Fabric Tree.
2. Open the Switch Administration window as described on page 31.
3. Click the FICON CUP tab.
The FICON CUP tabbed page displays, with the FICON Management Server subtabbed page in
front (see Figure 99 on page 220). All attributes on this page are read-only until FMS mode is
enabled.
