I am working in a new building where there are a lot of construction and power outages and our 6500 switches reboot unexpectedly. I think the issue is power fluctuations and/or low power input to our switches, but can not proof it to the contracting company providing power to the building. We have set up a Syslog server and it only tells us that the box was rebooted due to complete loss of PSU.
Is there any way to have syslog generates power/environment massages other then for a complete loss of PSU?
The problem is that since this is new building, we don't have enterprise management set up yet.
The closest SNMP command I found is:
snmp-server enable traps envmon
When the voltage keyword is used, a ciscoEnvMonVoltageNotification (enterprise MIB OID 188.8.131.52.184.108.40.206.13.3.2) is sent if the voltage measured at a given testpoint is outside the normal range for the testpoint (that is, at the warning, critical, or shutdown stage). For access servers, this notification is defined as the caemVoltageNotification (enterprise MIB OID 220.127.116.11.18.104.22.168.61.2.2).
Is there a way to send SNMP traps to a syslog server?
I had experience a situation like this and one of the solutions we got was to put a UPS in. The UPS we got included a 10BaseTx interface and it's connected to the switch. So when the building power goes off, the UPS will generate an alarm before the battery runs flat.
