Usage Guidelines
• When the system is set for critical event or a dying-gasp event, the local OAM entity indicates the
event through the OAMPDU flags to its peer OAM entity.
• In case of port admin down, the OAM IFU-PDU with dying-gasp bit set will be sent to peer as soon as
a failure is detected and transmission will continue till the specific port actually goes down.
• In case of takeover or reload of the switch, the OAM IFU-PDU with dying-gasp bit set will be sent to
peer as soon as a failure is detected and transmission will continue till the specific device actually goes
down.
down.
• The information PDUs with dying gasp bit set is transmitted towards peer as soon as link-down is
detected at NI. However, if there is a link flap (i.e link comes again) before the expiry of link-flap
timer, then normal information PDU transmission with dying-gasp bit reset shall resume. This will
cause clearing of alarms or trap on the peer port.
