Information About Fibre Channel Interfaces
Note Generation 2 Fibre Channel switching modules are not supported on the Cisco MDS 9216 switch;
however, they are supported by both the Supervisor-1 module and the Supervisor-2 module.
For detailed information about the installation and specifications for these modules and switches, refer
to the hardware installation guide for your switch.
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 6, ports 7 through 12, ports 13 through 18, ports 19 through 24, ports 25
through 30, 31 through 36, and ports 37 through 42, 43 through 48 are the port groups on the 48-port
8-Gbps Advanced Fibre Channel switching modules.
Table 3-2 shows the bandwidth and number of ports per port group for the Generation 2, Generation 3,
and Generation 4 Fibre Channel modules, and Generation 2 and Generation 3 Fabric switches.
