Port Groups; Creating A Port Group - Brocade Communications Systems Brocade BladeSystem 4/24 User Manual

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
