Configuring Oversubscription Ratio Restrictions
The 48-port and 24-port 4-Gbps, and all 8-Gbps Fibre Channel switching modules support
oversubscription on switches with shared rate mode configurations. By default, all 48-port and 24-port
4-Gbps, and 8-Gbps Fibre Channel switching modules have restrictions on oversubscription ratios
enabled. As of Cisco SAN-OS Release 3.1(1) and NX-OS Release 4.1(1), you can disable restrictions
on oversubscription ratios.
Table 22-21 describes the bandwidth allocation for oversubscribed interfaces configured in shared mode
on the 4-Gbps modules.
All ports in the 48-port and 24-port 4-Gbps modules can be configured to operate at 4 Gbps in shared
mode even if other ports in the port group are configured in dedicated mode, regardless of available
bandwidth. However, when oversubscription ratio restrictions are enabled, you may not have all shared
4-Gbps module ports operating at 4 Gbps.
