The tmnxPtpCardNotSupported notification is generated when the Precision Timing Protocol (PTP) is enabled on a card that is not capable of clock recovery using PTP. This notification is triggered when the TIMETRA-CHASSIS-MIB::tmnxCpmCardOscillatorType is not 'ocxo (3)', the tmnxPtpClockClockType is set to 'ordinarySlave (1)' or 'boundary (3)', and tmnxPtpClockAdminState is set to 'inService (2)'. [EFFECT] While this event is active, tmnxPtpClockOperState will be 'outOfService (3)' on the card that this notification was generated. [RECOVERY] This event is cleared when a replacement CPM card with an Oscillator of type 'ocxo (3)' is inserted. tmnxPtpCardNotSupportedClear is generated when this event is cleared.
