Information About Fibre Channel Interfaces
All ports in 8-Gbps Advanced Fibre Channel switching modules where bandwidth is shared support
1-Gbps, 2-Gbps, 4-Gbps, or 8 Gbps traffic. However, it is possible to configure one or more ports in a
port group to operate in dedicated rate mode with 1-Gbps, 2-Gbps, 4-Gbps, or 8 Gbps operating speed.
All ports in 4-Gbps Fibre Channel switching modules where bandwidth is shared support 1-Gbps,
2-Gbps, or 4-Gbps traffic. However, it is possible to configure one or more ports in a port group to
operate in dedicated rate mode with 1-Gbps, 2-Gbps, or 4-Gbps operating speed.
All ports in the 32-Port or 48-Port 8-Gbps Advanced Fibre Channel modules where bandwidth is shared
support 1-Gbps, 2-Gbps, 4-Gbps, or 8-Gbps traffic in a maximum or 32 or 48 ports.
All ports in the 48-Port and 24-Port 8-Gbps Fibre Channel switching modules where bandwidth is shared
support 1-Gbps, 2-Gbps, 4-Gbps, or 8-Gbps traffic.
In the 4/44-Port 8-Gbps Host-Optimized Fibre Channel switching module, all the ports where bandwidth
is shared support 1-Gbps, 2-Gbps, 4-Gbps in a maximum of 44 ports, or 8 Gbps in a maximum of 4 ports.
Dedicated Rate Mode Configurations for the 8-Gbps Modules
Table 3-7 shows the maximum possible dedicated rate mode configuration scenarios for the Generation
4 Fibre Channel modules.
Table 3-8 shows the maximum possible dedicated rate mode configuration scenarios for the Generation
3 Fibre Channel modules.
