1. By default, all ports in a 48-port 4-Gbps switching module operate in shared mode with administrative operating speed
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:
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.

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.
