SNMP Help - wrong state for failed fan

Trying to figureout what I'm doing wrong.  Have a Cisco 2821 router with Fan 3 not rotating.  SNMP setup to trap on fan status, but the state shows to be shutdown and not failed as the router messages would indicate.  The router is at a very remote location and I cannot verify if it's actually turning.  Just going by what's presented when accessing the router.

Anything I can do to change the state so that it triggers alerts on our monitoring system?

PP9-2821#show environment

Main Power Supply is AC

Fan 1 OK

Fan 2 OK

Fan 3 failed

Fan Speed : Normal

System Temperature: 35 Celsius (normal)

Environmental information last updated 00:00:25 ago

Hi mate...

dont you have some options like this ?

R1(config)#snmp-server enable traps envmon fan ?

  shutdown      Enable SNMP environmental monitor shutdown traps

  statuschange  Enable SNMP environmental monitor status change traps

  supply        Enable SNMP environmental monitor supply traps

  temperature   Enable SNMP environmental monitor temperature traps

  voltage       Enable SNMP environmental monitor voltage traps

i think statuschange would help....

SNMP Help - wrong state for failed fan

Thx for the info!

I did walk the MIB a bit more and found the envmon+fan+statuschange

Router snmp-server fan status change enabled.

Now I receive this message on the monitoring station:

ciscoEnvMonFanStatusChangeNotif.0

Response packet  contained the error: No Such Name

Still in the troubleshooting stage at the moment.
