Dying Gasp

If the switch loses all power it will maintain power long enough to send a Dying Gasp message before
completely shutting down. An SNMP trap, Syslog message and Link OAM PDUs will be generated.

Scenarios

A Dying Gasp event will be generated in the following scenarios:
Primary power supply failure (if only power supply present)
•
Primary power supply failure and then backup power supply failure
•
Backup power supply failure and then primary power supply failure
•
When a reload command is issued
•
When a takeover command is issued
•
Note. Connect each power supply to a separate independent power source to avoid simultaneous
power failures.

SNMP Trap

As soon as the power failure is detected, an SNMP trap is sent to the first three configured SNMP stations.
The trap includes the following information:
Slot number
•
Power supply type (primary/backup)
•
Time of the failure
•
Use the snmp station
configuring an SNMP station.

Syslog Message

As soon as the power failure is detected, the following Syslog message is sent to the first four configured
Syslog servers, along with the time of the failure:
Dying Gasp Power Failure Event Occurred
