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 PDCM 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 Group

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 Prohibit Dynamic Connectivity Mask

(PDCM) Allow/Prohibit Matrix for the port group. PDCM is a FICON port attribute that can be used to

prohibit communication between specific ports. For more information about the PDCM

Allow/Prohibit Matrix, refer to “Configuring a PDCM Allow/Prohibit Matrix” on page 468.
