This read-write TruthValue controls whether SNMP dying gasp is enabled on the Ethernet NTU Card, letting it send a final notification the instant it loses power. An admin cares because dying gasp gives a last signal that distinguishes a power loss from a silent network failure at a remote site. For example, an admin enables ethernetNTUCardSnmpDyingGaspEnabled on a remote NTU so a power outage at that site generates an immediate alert rather than the device just going silent.
