By default, all ports in a 48-port 4-Gbps switching module operate in shared mode with administrative operating speed set to auto. All ports in a 48-port 4-Gbps switching module can operate in dedicated mode with a 1-Gbps operating speed. However, if you configure one or more ports to operate in 2-Gbps or 4-Gbps dedicated mode, some of the other ports in the module would have to operate in shared mode. Note Port groups are defined by the hardware and consist 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. Port Rate Modes The Port rate mode configuration is used to determine the bandwidth allocation for ports in a port group. Two port rate modes are supported: Dedicated Mode and Shared Mode. In Generation 1 modules, port rate mode is not configurable by users; rather, it is determined implicitly based on the port mode and linecard type. In Generation 2 modules, port rate mode is user-configured.
