1. Dedicated bandwidth with no oversubscription
2. Dedicated bandwidth or oversubscribed using shared buffer resources.
Port groups are defined by the hardware and consist of sequential ports. For example, ports 1 through
Note
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.
