Port Groups
Each module or switch can have one or more ports in port groups that share common resources such as
bandwidth and buffer credits. Port groups are defined by the hardware consisting of sequential ports. For
example, ports 1 through 12, ports 13 through 24, ports 25 through 36, and ports 37 through 48 are the
port groups on the 48-port 4-Gbps Fibre Channel switching modules.
