Execute an Action upon Exceeding the High Threshold
When an error exceeds the low threshold , an event notification is sent to the peer. When an error exceeds
the high threshold , a pre-defined action is triggered such as disabling the interface.
Remote Failure Indication
Remote Failure Indication is the mechanism a system uses to notify its peer of a local critical link event.
There are three critical events; each has an associated flag which can be set in the OAMPDU when the
event occurs.
• Link Fault —A fault occurred in the receive direction of the local peer.
• Dying Gasp —An unrecoverable local failure condition occurred. Dying Gasp notification is not
supported on S-Series.
• Critical Event —An unspecified critical event occurred. Critical Event notification is not supported on
S-Series.
When a link fault, dying gasp, or critical event occurs, the system sets an associated bit in subsequent
OAMPDUs until the error is resolved (polling occurs every 100ms), and you can configure the system to
take an additional action.
Specify the time period for error
second per time period condition.
