Port groups
A port group is a group of FC ports from one or more switches within the same fabric. Port groups
are user-specific; you can only view and manage port groups that you create.
The ports display in the order in which you add them to the port group. The order in which you add
ports to a port group is persisted in both the port group and the Allow/Prohibit Matrix. While port
groups can be at the fabric level (ports from multiple switches within the same fabric), the
Allow/Prohibit Matrix is at the switch level. Therefore, when you view the Allow/Prohibit Matrix for a
port group with ports from multiple switches, the matrix only shows the ports for the selected
switch.
To reorder the ports, you must remove the ports, save your changes, then open the Port Groups
dialog box and add the ports back to the port group in the new order.
Once you create a port group, you can view and edit the Allow/Prohibit Matrix for the port group.
Allow/Prohibit Matrix is a FICON port attribute that can be used to prohibit communication between
specific ports. For more information about the Allow/Prohibit Matrix, refer to
“Configuring an
Allow/Prohibit Matrix” on page 1025.

At least one switch must be reachable to create a port group.
