Introduction

Dying Gasp is a feature that is available only on the Catalyst 1300 series switches and provides a mechanism to alert monitoring systems that the device is experiencing an unexpected loss of power before it loses connection. When a loss of power event occurs, a hardware capacitor will delay the device shutting down for a short time. During this time, the device will send Dying Gasp messages via configured Syslog servers or SNMP notification recipients that can be used to identify the cause of the issue and troubleshoot.

You can configure Dying Gasp via the CLI using simple commands. Keep reading to find out more.
