 Description   
  1. switch Cisco catalyst C9300-48P (X86)
  2. system image: Cisco IOS Software [Fuji], Catalyst L3 Switch Software (CAT9K_IOSXE), Version 16.8.1a, RELEASE SOFTWARE (fc1)
  3. temperature sensor HotSpot is not recognized.
  4. Alarm on temperature above 60 degree is triggered

On the switch cisco WS-C3850-12S (MIPS) processor (revision L0), Cisco IOS Software [Everest], Catalyst L3 Switch Software (CAT3K_CAA-UNIVERSALK9-M) HotSpot is correctly recognized.

Of course it is a different version of system software, but it is still IOS.

 

EXPECTED RESOLUTION:

In the IOS there are thresholds defined and it should be accessible via snmp.

Alerts should be related to this values and calculated due to its state.

system command

>show environement temperature on both models gives the following results:

Switch 1: SYSTEM TEMPERATURE is OK
Inlet Temperature Value: 29 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 46 Degree Celsius
Red Threshold    : 56 Degree Celsius

Hotspot Temperature Value: 55 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 105 Degree Celsius
Red Threshold    : 125 Degree Celsius
Switch 2: SYSTEM TEMPERATURE is OK
Inlet Temperature Value: 27 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 46 Degree Celsius
Red Threshold    : 56 Degree Celsius

Hotspot Temperature Value: 56 Degree Celsius
Temperature State: GREEN
Yellow Threshold : 105 Degree Celsius
Red Threshold    : 125 Degree Celsius

Hello Kazimierz,

temperature sensor HotSpot is not recognized.

What do you mean by not recognized? The sensor is not monitored at all? Monitored but not supported? If yes, please show the error.

Alarm on temperature above 60 degree is triggered

Do I understand you correctly, you would like to be able, to define thresholds for triggers dynamically from received data?

Hello Edgars!

It looks like it should be - or other macros ( dedicated for various hotspot sensors) ma be defined ( statically) for dedicated use.

The second is much simpler to be defined...

Hello Kazimierz,

Is this issue still valid?

Comment by Trevor Adamo [ 2019 Dec 30 ]

How was this closed as unable to reproduce? This occurrs on all my 3850 Switches for the temp sensor 2.

Did anyone come up with a way to modify the config with different thresholds for sensor 1 and sensor 2?
