ALM-4286193664 The SPR link status has changed

Description

SPR/4/SPRLINKCHANGE:OID [oid] SPR Link-state changed .LinkStateIndex = [integer], LinkStateName = [octet], LinkStateEligibility = [integer].

This alarm is generated when link quality parameters on a detection link become correct or incorrect.

Parameters

Name

Meaning

OID

Indicates the MIB object ID of the alarm.

LinkStateIndex

Indicates the index. The value ranges from 1 to 65535.

LinkStateName

Indicates the interface name.

LinkStateEligibility

Indicates the link status:

  • 0: indicates that the link is Up.
  • 1: indicates that the link is Down.

Impact on the System

  • If a detection link reports this alarm when SPR is configured, the link may be unavailable.
  • If a link sometimes reports this alarm, services may be switched normally.
  • If a link frequently reports this alarm, link flapping occurs.

Possible Causes

  1. Traffic is switched between links.
  2. The link configuration is incorrect.
  3. The threshold configuration is incorrect.
  4. The link fails.

Procedure

  1. Run the display smart-policy-route link-state command to view the detection link status.
    • Check whether the loss ratio is 1000. If yes, the link is faulty. Go to step 4.
    • Check whether the delay, jitter, loss ratio, and CMI are correct. If yes, go to step 2.
    • If the link status is not found, go to step 3.
  2. Run the display smart-service-profile service-map name command to view thresholds for link quality parameters.
    • Check whether the link meets service requirements based on the link status. If link does not meet service requirements, services may be switched between links. Go to step 5.
    • Check whether the thresholds for link quality parameters are correct. If the thresholds for link quality parameters are incorrect, set correct thresholds for link quality parameters.
      • Run the set delay threshold threshold-value command to set the threshold for the delay.
      • Run the set jitter threshold threshold-value command to set the threshold for the jitter.
      • Run the set loss threshold threshold-value command to set the threshold for the loss ratio.
      • Run the set cmi threshold threshold-value command to set the threshold for the CMI.
      • Run the cmi-method cmi-method command to set the CMI formula.

      Go to step 5.

  3. Run the display nqa results [ test-instance admin-name test-name ] command to check whether the NQA test instance type is jitter.
    • If the NQA test instance type is jitter, the link is faulty. Go to step 4.
    • If the NQA test instance type is not jitter, reconfigure an NQA test instance and detection link. Go to step 5.
  4. Collect the alarm information, log information, and configuration information, and then contact technical support personnel.
  5. End.
