We have two redundant power supplies and one is reporting faulty with the show env power command.

POWER SUPPLY A is DC OK

POWER SUPPLY B is DC FAULTY

The SNMPWALK on the MIB 1.3.6.1.4.1.9.9.13.1.5.1.3 is reporting both as normal.

ciscoEnvMonSupplyStatusTable (1.3.6.1.4.1.9.9.13.1.5) for status

The IOS is ies-lanbasek9-mz.122-58.SE2. Is this a known issue or is there a workaround?

  • Cisco Employee,

It would be good if you can share debug output from device for snmp while polling it to this OID.

Also, please check if your device is configured for "power-supply dual" command to reflect right information?

-Thanks

Yes the switch is configured for power-supply dual and I have attached a copy of the SNMPwalk which is a polling of the OID.

It appears power cycling the switch corrected the problem. Thanks for you assistance.

  • Cisco Employee,

Thanks for update and this seems to be one of the sure-shot fix for many issues with SNMP mismatch.

I checked a few old issues and they seems to be asking for reboot, but I wanted to check if this is some sort of defect.

Glad to know it has resolved for you.

Cheers..

-Thanks
