Port Groups and Port Rate Modes
Table 22-5 show the amount of bandwidth reserved for a configured port speed on 4-Gbps switching
modules.
Note The 4-Port 10-Gbps Fibre Channel module ports in auto mode only support auto speed mode at 10 Gbps.
Shared Rate Mode
When port rate mode is configured as shared, multiple ports within a port group share data paths to the
switch fabric so that fabric bandwidth and related resources are shared. Often, the available bandwidth
to the switch fabric may be less than the negotiated operating speed of a port. Ports in this mode use local
buffering for the BB_credit buffers.
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 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 22-2 shows the maximum possible dedicated rate mode configuration scenarios for the Generation
3 Fibre Channel modules.
