Hardware Sensor smtp trap failure

[fatihucar67]

Hi.

We have a monitoring tool. We are constantly faced with such an error 3750x switch

"Hardware Sensor Name : Sw1, PS1 Faulty, RPS NotExist. Category : power. Current State : notFunctioning(6) - The sensor is operating under critical or fatal conditions. This may directly affect the functioning of both the sensor and related components."

what is the source of this problem?

 - Could be harmless, if all power supplies are OK. Check using show env all ; possibly upgrade to a gold-starred release, if current version is below such trains. Check if message persist afterwards.

   - Since the RPS (port) is not used; the message is probably bogus

Yes it looks like it is probably this bug

Unexpectedly sending ciscoEnvMonSupplyStatusEntry as PS faulty

CSCui31295

Description

Symptom:
In some power supplies for C3560X/C3750X, if you enable SNMP trap, PS notification trap is sent intermittently even if it is good.
This bug is related to CSCud01798, PS notification trap should be suppressed as well as syslog message.

Conditions:
The issue may be seen in C3560X/C3750X running 15.0(2)SE or later.

Debug snmp packet
SNMP: Packet sent via UDP to x.x.x.x
SNMP: Queuing packet to x.x.x.x
SNMP: V1 Trap, ent ciscoEnvMonMIBNotificationPrefix, addr x.x.x.x, gentrap 6, spectrap 9
ciscoEnvMonSupplyStatusEntry.2.1058 = Sw1, PS1 Faulty, RPS NotExist
ciscoEnvMonSupplyStatusEntry.3.1058 = 6
SNMP: Packet sent via UDP to x.x.x.x
SNMP: Queuing packet to x.x.x.x
SNMP: V1 Trap, ent ciscoEnvMonMIBNotificationPrefix, addr x.x.x.x, gentrap 6, spectrap 9
ciscoEnvMonSupplyStatusEntry.2.1058 = Sw1, PS1 Normal, RPS NotExist

Workaround:
Ignore SNMP traps, check "show env all" command to know actual PS status.
