Understanding SNMP MIB for Timing on ACX Series

Junos OS for ACX Universal Metro Routers supports SNMP get, get-next, and walk management capabilities for timing features. These capabilities are enabled through the PTP MIB, SyncE MIB and GPS MIB timing objects.

Note:

The PTP MIB and SyncE MIB timing objects are grouped under the jnxTimingNotfObjects SNMP MIB object.

Table 1 shows the list of SNMP MIB objects supported for SNMP get, get-next, and walk management on ACX Universal Metro Routers.

Table 1: SNMP MIB Objects for get, get-next, and walk management

SNMP MIB

Object

Description

PTP MIB

jnxPtpServoState

Denotes the following PTP Servo states:

  • INITIALIZING

  • ACQUIRING

  • PHASE ALIGNED

  • FREERUN

  • HOLDOVER

  • FREQUENCY LOCKED

jnxPtpServoStateStr

Denotes the PTP Servo state string:

  • INITIALIZING

  • ACQUIRING (Primary is elected and servo starts acquiring lock)

  • PHASE ALIGNED (Locked to Primary)

  • FREERUN (no PTP source available)

  • HOLDOVER (Member locked to PTP for more than 12 hours and then loses all the PTP sources)

jnxPtpClass

Denotes the class of the PTP reference clock.

jnxPtpGmId

Denotes the PTP reference clock identifier.

SyncE MIB

jnxClksyncQualityCode

Denotes the SSM/ESMC quality level of the locked source in decimal format.

jnxClksyncQualityCodeStr

Denotes the SSM/ESMC quality level of the locked source in string format

jnxClksyncIfIndex

Denotes the interface index of the locked source in decimal format.

jnxClksyncIntfName

Denotes the interface name of the locked source in string format.

GPS MIB

jnxGpsRecvStatus

Displays the status of the GPS receiver.

Note:
  • The SNMP get and walk management are supported only for scalar objects.

  • For SyncE objects, the jnxClksyncQualityCode, jnxClksyncQualityCodeStr, jnxClksyncIfIndex, and jnxClksyncIntfName objects displays only for locked source.

You can use the show chassis synchronization extensive, show ptp lock-status detail, show snmp mib get <MIB-timing-objects>, and show snmp mib walk jnxTimingNotfObjects show commands for monitoring and troubleshooting purposes.

The following are the sample show command outputs for reference:
