Syntax: show fan-threshold
The output displays the following information.
When syslog messages display a change in fan speed, you can identify which sensors triggered the change by checking show chassis
and show fan-threshold command output and looking for sensors with temperatures near threshold boundaries.Table 40 lists the
associations between the show chassis, show fan-threshold, and fan-threshold commands.
TABLE 39 Temperature threshold information for modules and fan speeds
This field... Displays...
Thermal Sensor Control Block
(THERMAL_SENSOR_TEST_RUL
E_<module>)
The temperature threshold information for the various modules. The
<module> parameter indicates the following:
MP – The active management module
STANDBY_MP – The standby management module
SNM – The switch fabric module
LP – An interface module
Fan Speed Low or Med or Med-Hi
or Hi
The current setting of the low and high temperature thresholds for the low,
medium, medium-high, and high fan speeds.
NOTE: As indicated in Table 38 on page 224, the low fan speed for each
module does not have a default low temperature threshold value, nor
can you configure this value. The “-1” value that appears in the Fan
Speed Low field for each module is a Brocade internal value only.
State = 0 (FAN_STATE_LOW) For Brocade internal use only.
max_ts_shut_off_count For Brocade internal use only.
shut_off_count = 0 0 0 0 0 0 0 0 For Brocade internal use only.
