3750-X redundant power supply monitoring

[markschnabel]

            We have 3750-X's with dual power supplies. When one of them is disconnected the NMS/Netcool is not picking up the trap. What MIB is needed to monitor the power supplies?

Thanks

Hi Mark.

Check your snmp configuration on the device. 

You will want to check configuration on 3750 for PS /Fan / Temp issue -

"snmp-server enable traps envmon fan shutdown supply temperature status"

Those map to receiving envmon traps. FYI - http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a05.shtml

envmon - Sends Cisco enterprise-specific environmental monitoring notifications when an  environmental threshold is exceeded. When the envmon keyword is used, you can specify  a notification-option value.

This is from the CISCO-ENVMON-MIB, and the notifications are:  enterprise 1.3.6.1.4.1.9.9.13.3    

1 ciscoEnvMonShutdownNotification    

2 ciscoEnvMonVoltageNotification    

3 ciscoEnvMonTemperatureNotification    

4 ciscoEnvMonFanNotification    

5 ciscoEnvMonRedundantSupplyNotification

Please let me know if this is helpful.
