configureChassis 2 System attributes The following system-related parameters are configurable on a Virtual Fabric-aware switch. system.blade.bladeFaultOnHwErrMsk If this field is set to a value other than 0, then any nonfatal HW ASIC data parity error causes the problem blade to be powered off. The valid range is 0x0 to 0xffff. The default value is 0x0. system.cpuLoad Sets a threshold to define internally when the CPU is busy. The default threshold is 121, which represents a CPU instantaneous load average of 1.21 in the or top command. The range is 10 to 121 (representing CPU load thresholds of .10 to 1.21). system.i2cTurboCnfg Configures the i2c driver that manages processing of the i2c interrupts. The I2C Turbo mode is enabled (Setting 1) by default on all 16G platforms running Fabric OS v7.0 or later. The mode is disabled by default for any switches capable of running Fabric OS v6.4x and Fabric OS v6.3x. An upgrade preserves the pre-upgrade configuration. The value shown in brackets is the current value. The following values are supported: 0 Disables the I2C Turbo mode. When the I2C Turbo mode is disabled, every byte received by an i2c interrupt is scheduled for processing by the given task or process. This permits other high priority processes to complete, thereby allowing for possible delay in the receipt of the I2C response message. 1 Enables the I2C Turbo mode for SFP transceivers only. This is the default setting. When the I2C Turbo mode is enabled, every I2C byte received from an SFP transceiver is processed by the interrupt handler itself, thus preventing any higher priority processes from preempting this processing. 2 For internal use only. fos attributes The following chassis-wide CS_CTL mappings can be modified: CSCTL QoS Mode Configures the CS_CTL to virtual channel (VC) mapping. This operation is disruptive and therefore you must disable all edge blades after you change the CS_CTL to VC mapping. 0 Clears any previously configured CS_CTL to VC mapping and sets one-to-one mapping between a CS_CTL value and VC number for Condor2 and Condor3 ASIC. The CS_CTL values are divided into three groups: 1-8 (low priority), 9-16 (medium priority), and 17-24 (high priority). This is the default mode. 1 Sets the CS_CTL to VC mapping to support three CS_CTL values: 1 (low priority), 2 (medium priority), and 3 (high priority). Each CS_CTL value can map to more than one VC depending on the underlying support from ASIC. This is the auto mode. For more information about CS_CTL-based frame prioritization, refer to the Fabric OS Administrator's Guide. Fabric OS Command Reference 167 53-1002746-01
