Remote Failure Indication
Faults in Ethernet that are caused by slowly deteriorating quality are more difficult to detect than completely disconnected links. A flag in the OAMPDU allows an OAM entity to send failure conditions to its peer. The failure conditions are defined as follows:
- Dying gasp: This condition is detected when the receiver goes down. The dying gasp condition is considered as unrecoverable. The conditions for a dying gasp condition include:
- Critical event: On any critical event, the DTE will set the critical event bit in the information OAMPDU. The device will generate critical event in the following cases:
The battleshort mode allows you to prevent the shutdown of ICX 8100 and ICX 8200 devices when the temperature of the box breaches the warning or shutdown threshold. This is intended to be used in emergency conditions to allow the switches to function in a hostile environment as long as possible.
