Custom Attributes
The following custom attributes can be modified.
config Index
OEM custom configuration. The range is 0 through 10000. The default is 0. This
attribute is for internal use only.
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.
