Dying-gasp PDU generation

Junos OS supports the generation of dying-gasp protocol data units (PDUs) on supported platforms. Dying gasp refers to an unrecoverable condition such as a power failure. In this condition, the local peer informs the remote peer about the failure state. When the remote peer receives a dying-gasp PDU, it takes an action corresponding to the action profile configured with the link-adjacency-loss event.

Supported platforms can generate and receive dying-gasp packets. When LFM is configured on an interface, a dying-gasp PDU is generated for the interface on the following failure conditions:

• Power failure
• Packet Forwarding Engine panic or a crash
