Chapter 20 R Commands rate-mode oversubscription-limit Send documentation comments to [email protected] rate-mode oversubscription-limit To enable or disable restrictions on oversubscription ratios, use the rate-mode oversubscription-limit command. rate-mode oversubscription-limit module module number no rate-mode oversubscription-limit module module number Syntax Description module module-number Identifies the specific module on which oversubscription ratio restrictions will be enabled or disabled. Defaults Oversubscription ratios are restricted for all 24-port and 48-port switching modules. Command Modes Configuration mode. Command History Release 3.1(1) Modification This command was introduced. Usage Guidelines When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed (if the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps). You must explicitly shut down and take out of service shared ports before disabling oversubscription ratio restrictions on them. The configuration is not saved to the startup configuration unless you explicitly enter the copy running-config startup-config command. Caution You must enable restrictions on oversubscription ratios before you can downgrade modules to a previous release. Examples The following example disables restrictions on oversubscription ratios for a module (there are only dedicated ports, so a shutdown is not necessary). switch# config t switch(config)# no rate-mode oversubscription-limit module 2 The following example shows how to viewthe status of a module's oversubscription ratios. switch# show running-config version 3.1(1) ... no rate-mode oversubscription-limit module 2 interface fc2/1 switchport speed 2000 OL-16217-01, Cisco MDS SAN-OS Release 3.x Cisco MDS 9000 Family Command Reference 20-13
