802.3ah | 99Adjust the OAMPDU Transmission ParametersLink Performance Event MonitoringLink Performance Event Monitoring OAM monitors the receive side of a link for a set of pre-definederrors and executes an action when a threshold is exceeded; it is enabled by default. Both peers on the linkmust be have link performance event monitoring enabled for discovery to complete.There is a high and low threshold for each pre-defined error; an event occurs when any threshold isexceeded. FTOS periodically polls hardware registers for the current frame and symbol error count. If aninterface exceeds a threshold, a notification is sent to the peer and the interface is placed in error-disabledstate.• Enable Error Monitoring on page 99• Execute an Action upon Exceeding the High Threshold on page 102Enable Error MonitoringThe polling interval for Link Performance Monitoring is 100 milliseconds.Task Command Syntax Command ModeSpecify a the maximum or minimumnumber of OAMPDUs to be sent persecond.ethernet oam [max-rate value | min-rate value]Range: 1-10Default: 10INTERFACESet the transmission mode to active orpassive.ethernet oam mode {active | passive}Default: ActiveINTERFACESpecify the amount of time that thesystem waits to receive an OAMPDUfrom a peer before considering itnon-operational.ethernet oam timeout valueRange: 2-30 secondsDefault: 5 secondsINTERFACETask Command Syntax Command ModeStart (or stop) Link PerformanceMonitoring on an interface.ethernet oam link-monitor onno ethernet oam link-monitor onDefault: EnabledINTERFACEEnable (or disable) support for LinkPerformance Monitoring on an interface.ethernet oam link-monitor supportedno ethernet oam link-monitor supportedDefault: EnabledINTERFACE
