[c-nsp] Monitoring 3750x power supplies

[Aaron Riemer]

Hey guys,

 

We are having issues monitoring our 3750x power supplies via the cisco
envmon MIB that hopefully someone out there has experienced.

 

When one of the power supplies loses power the OID will change state to
6:notFunctioning but once power is reset the state does not change back to
normal. 

 

This is causing issues for our monitoring application.

 

See below for the OID:

 

Object ciscoEnvMonSupplyState OID 1.3.6.1.4.1.9.9.13.1.5.1.3 Type
CiscoEnvMonState 
1:normal
2:warning
3:critical
4:shutdown
5:notPresent
6:notFunctioning
Permission read-only Status current MIB 

Description The current state of the power supply being instrumented.

 

snmpwalk result:

 

SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1058 = INTEGER: 1

SNMPv2-SMI::enterprises.9.9.13.1.5.1.3.1086 = INTEGER: 6

 

switch#show env power

 

SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts

---  ------------------  ----------  ---------------  -------  -------

1A  C3KX-PWR-1100WAC    xxxx OK              Good     Good     1100/0

1B  C3KX-PWR-1100WAC    xxxx OK              Good     Good     1100/0

 

Any ideas? I believe a reload of the switch will resolve but we can't do
this for every switch that loses power to one of the supplies.

 

Thanks,

 

Aaron.
