tmnxPtpCardNotSupported

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.1

Default severity

minor

Message format string

CPM $tmnxCpmCardSlotNum$ does not support IEEE1588 (PTP) operation for the configured clock-type

Cause

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.

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.5

Default severity

minor

Message format string

IEEE1588 (PTP) Card $tmnxChassisNotifyHwIndex$ out of resources

Cause

The tmnxPtpOutOfResources notification is generated when the Precision Timing Protocol (PTP) process on the card is out of resources. This may occur in either two situations: 1. The number of PTP peers exceeds the system limit. 2. The total unicast packet rate negotiated with all PTP peers has reached the maximum packet rate supported by the system. Exceeding this rate would impact the ability of the master clock to provide an accurate stream of timing packets to each remote slave clock. If either of the two situations above occur, the PTP process will reject any new unicast packet requests from remote slave PTP peers. tmnxPtpOutOfResourcesClear is generated when this event is cleared.

tmnxPtpPeerNoTimestamping

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.13

Default severity

minor

Message format string

Timestamping of transmit and receive communications with peer $tmnxPtpPeerIpAddress$ is performed at the CPM. Performance may be degraded.

Cause

The tmnxPtpPeerNoTimestamping notification is generated on initial exchange of PTP event messages with a peer and whenever the location of the timestamping of the event messages exchanged with the peer changes, and the location is 'cpm (2)'.

Effect

When the timestamping location is 'cpm (2)', the accuracy of the PTP event messages is less then if the messages are timestamped at the port and performance will be negatively impacted.

Recovery

It may be necessary to check the capabilities of the port being used for the messages and/or to modify routing to direct the messages to an alternate port. Some reasons for a port to not perform timestamping include: not configured, port not configured for ptp-hw-assist, port does not support ptp-hw-assist.

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.14

Default severity

minor

Message format string

Timestamping of transmit and receive communications with peer $tmnxPtpPeerIpAddress$ is now performed at the port.

Cause

The tmnxPtpPeerNoTimestampingClear notification is generated when the conditions that caused the tmnxPtpPeerNoTimestamping event have been resolved and result in the location of the timestamping of the event messages exchanged with the peer being changed from 'cpm (2)' to 'port (1)'.

Effect

When the timestamping location is the 'port (2)', the accuracy of the PTP event messages is optimal.

Recovery

No recovery is required for this notification.

tmnxPtpPortNoTimestamping

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.8

Default severity

minor

Message format string

Port $tmnxPtpNotifyPortId$ does not support PTP port-based timestamping. Performance may be degraded.

Cause

The tmnxPtpPortNoTimestamping notification is generated when a PTP port is created and the associated Ethernet port does not support IEEE 1588-2008 port-based timestamping.

Effect

The PTP port is created but the performance may be degraded due to timestamping at the CPM. For optimal performance, ensure PTP is enabled on ports with IEEE 1588-2008 port-based timestamping capability.

Recovery

The Ethernet port used for the PTP port should be changed to a port on an MDA that supports IEEE 1588-2008 port-based timestamping.

tmnxPtpPortPtsfUnusable

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.9

Default severity

minor

Message format string

Packet timing signal from PTP port $tmnxPortPortID$ neighbor $tmnxPtpPortNeighborMacAddress$ is unusable.

Cause

The PTP process detected excessive noise between the local port and the indicated external Master port.

Effect

Any Announce messages received from the indicated neighbor shall be excluded from the BMCA algorithm until this condition is cleared.

Recovery

The cause of the excessive noise should be identified and corrected. Once resolved, the clear command for this neighbor port must be executed to clear the condition and allow Announces from this neighbor to be considered in the BMCA.

tmnxPtpRequiresSystemReboot

SNMP notification prefix and OID

TIMETRA-PTP-MIB.tmnxPtp1588Notifications.10

Default severity

major

Message format string

The PTP configuration (clock-type $tmnxPtpClockClockType$, profile $tmnxPtpClockProfile$) is different than the initial configuration (clock-type $tmnxPtpNotifyInitialClockType$, profile $tmnxPtpNotifyInitialProfile$). A system reboot is required for the change to take effect.

Cause

The PTP configuration has changed since system initialization. On some SROS series systems, changing the tmnxPtpClockClockType or tmnxPtpClockProfile requires a system reboot to take effect.

Effect

PTP remains operationally out of service, even though it has been administratively enabled.

Recovery

Reboot the system, or change the clock configuration to the original configuration.

Message format string

The PTP configuration has changed to the initial configuration. A system reboot is no longer required.

Cause

The system generates the tmnxPtpRequiresSystemRebootClear notification when the user changes the PTP configuration to match the initial configuration.

Effect

PTP does not require a system reboot to become operationally in service.

There is no recovery required for this notification.
