In this interface, you can query and set the clock source reversion parameter.

Navigation Path

In the NE Explorer, choose Configuration > Clock > Physical Clock > Clock Source Switching. Click Clock Source Reversion tab.

Parameters

**Table 1** Descriptions of the parameters for an UNI Port
Field	Value	Description
NE Name	Default: NE101	Displays the name of the source NE of a clock source.
High-Priority Clock Source Reversion	Auto-Revertive, Non-Revertive	When a higher priority clock source degrades, the NE will automatically switch to a clock source with lower priority. If Auto-Revertiveis set, when the high-priority clock source recovers, the NE will automatically switch back to the high-priority clock source. On the contrary, if Non-Revertive is set, the NE will not automatically switch back to the higher priority clock source.
Clock Source WTR Time (min)	0 to 12	This parameter specifies the duration from the time when the clock source restoration is detected to the time when the clock source switching is triggered. This parameter is used to avoid frequent switching of the clock source due to instability of the clock source state within a short time. This parameter is valid only when High-Priority Clock Source Reversion is set to Auto-Revertive. NOTE: The working mode of the NE must be set to BC, OC or TC+OC. Set Clock Source WTR Time (min) within the range of 0 minutes to 12 minutes at a spacing of 1 minute. By default, the WTR time is 5 minutes.
