Chapter 5 Troubleshooting Mixed Generation Hardware
Overview
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.
The 4-port 10-Gbps Fibre Channel switching module supports 10-Gbps port rates. The rest of the
Generation 2 modules support 1-Gbps, 2-Gbps, 4-Gbps, or autosensing port rates.
For detailed information about the installation and specifications for these modules, refer to the
hardware installation guide or the Configuration guides at the following website:
http://cisco.com/en/US/products/ps5989/tsd_products_support_series_home.html.
This section explains the features of Generation 2 modules and includes the following topics:
• Port Groups, page 5-2
• Port Speed Mode, page 5-3
• Dynamic Bandwidth Management, page 5-3
• Out-of-Service Interfaces, page 5-4
• Port Index Availability, page 5-4
Port Groups
Each module has four groups of one or more ports in port groups that share common resources, such as
bandwidth and buffer credits. Table 5-2 shows the port groups for the Generation 2 Fibre Channel
switches and modules.
