display clock source freq-deviation

Function

The display clock source freq-deviation command displays the frequency offset value of a clock source.

Format

display clock source freq-deviation [ slot slot-id ]

Parameters

Parameter	Description	Value
slot slot-id	Specifies a slot ID.	The value depends on the device configuration.

1: Monitoring level

Usage Guidelines

To view the frequency offset value of a clock source, run the display clock source freq-deviation command. If the frequency offset value is greater than or equal to the specified threshold, the frequency offset is abnormal. If the frequency offset value is less than the threshold, the frequency offset is normal.

Precautions

If frequency offset check is not enabled, this command also displays the frequency offset check result of the clock source. The check result, however, is not used for clock source selection.
A clock source that does not pass the frequency offset check is tagged "--".

Example

# Display the frequency offset result of the clock source in slot 2.

<HUAWEI> display clock source freq-deviation slot 2
 Frequence deviation detect:     enable

**Table 1** Description of the **display clock source freq-deviation** command output
Item	Description
Source	Interface clock source or PTP clock source with synchronous Ethernet enabled
Freq-deviation-value	Frequency offset value, which is in the format of symbol (negative sign only) + frequency offset value + unit (ppm) + frequency offset status. If the value is "---", the frequency offset check cannot be performed on the clock source.
