Alarm snmp on the fan detected but not visible on my switch

mhassine · ‎02-09-2022

Hello,

I have configure an alarm snmp for the fan status. I use the MIB "CISCO-ENVMON-MIB".

Here are the different state of a fan :

CiscoEnvMonState ::= TEXTUAL-CONVENTION

STATUS current

DESCRIPTION

"Represents the state of a device being monitored.

Valid values are:

normal(1): the environment is good, such as low

temperature.

warning(2): the environment is bad, such as temperature

above normal operation range but not too

high.

critical(3): the environment is very bad, such as

temperature much higher than normal

operation limit.

shutdown(4): the environment is the worst, the system

should be shutdown immediately.

notPresent(5): the environmental monitor is not present,

such as temperature sensors do not exist.

notFunctioning(6): the environmental monitor does not

function properly, such as a temperature

sensor generates a abnormal data like

1000 C.

My snmp tool return an alarm with the argument : notFunctioning (6) on a power supply's fan

When i connect on my switch, i check the fan status with the command show environment status, i can see the fan sensor is good. (my alarm is on the equipment with the red arrow)

Why have I an alarm snmp on this fan ?

Thanks for your answers.

Regards,

P.S : Sorry for my english, It is maybe bad.
