CLOCK/4/FREQ_INSTANT_CHG

CLOCK/4/FREQ_INSTANT_CHG

Message

CLOCK/4/FREQ_INSTANT_CHG:The frequency changes instantly. (Value=[LONG], Count=[ULONG])

Description

The number of frequency changes is not 0. The log records the latest change and number of frequency changes.

Parameters

Parameter Name Parameter Meaning

[LONG]

Indicates the latest frequency after change.

[ULONG]

Indicates the counter of frequency change.

Possible Causes

The performance of the traced clock source degrades or the jitter occurs.

Procedure

  • If the clock source is switched, this is a normal situation.
  • If the clock source of the upstream device is switched, this is a normal situation.
  • Run the display clock { bits0 | bits1 } command to view the BITS interface configuration. Check whether the clock configurations of upstream and downstream devices are correct, for example, whether bit/hz in the output mode of the upstream device is the same as that in the input mode of the local device.
  • Check the frequent offset of the upstream clock source. Tools may be required.
  • After the clock source is switched, if the log is generated on all interfaces of the local device, the local clock board may be faulty. Then perform an active/standby switchover on the clock boards.
  • Record this log message and contact technical support personnel.
