Dying Gasp - Cisco IE-4000 Software Configuration Manual

Dying Gasp

This chapter describes the Dying-Gasp feature for the Cisco Industrial Ethernet series switches.
Dying Gasp resides on a hardware component on the High-performance WAN Interface Card (HWIC) and supports
Gigabit Ethernet interfaces. The networking devices rely on a temporary back-up power supply on a capacitor, that allows
for a graceful shutdown and the generation of the dying-gasp message. This temporary power supply is designed to last
from 10 to 20 milliseconds to perform these tasks.
Dying-Gasp packets are created when you configure the host by using the dying-gasp configuration command. The
show dying-gasp packets command displays the detailed information about the created packets.
The SNMP server for the SNMP Dying Gasp message is specified through the snmp-server host configuration
command. The syslog server sending the syslog Dying Gasp message is specified through the logging host
hostname-or-ipaddress transport udp command. The Ethernet-OAM Dying Gasp packets are created for interfaces
where Ethernet-OAM is enabled.
Dying Gasp packets can be sent to a maximum number of 5 servers for each notification type.
