The fields that can be configured in PTP Boundary Clock Settings are described below: Parameter Priority 1 Priority 2 Description Enter the PTP boundary clock Priority 1 value here. The priority 1 attribute is used in the execution of the Best Master Clock algorithm. A lower value takes precedence. Zero indicates the highest precedence. The range is from 0 to 255. Enter the PTP boundary clock Priority 2 value here. The priority 2 attribute is used in the execution of the Best Master Clock algorithm. A lower value takes precedence. In the event that the BMC algorithm fails to order the clocks based on the values of priority 1, the clock's class, and the clock's accuracy; the priority 2 attribute will allow the creation of lower values compared to the other devices. Zero indicates the highest precedence. The range is from 0 to 255. Click the Apply button to accept the changes made. When the stacking mode is enabled and the member ports of the trunk group exist in different stack units, the PTP function may not function properly. For example: • The PTP feature will function properly when the member ports receive and send PTP messages on the same stacked unit. • The PTP feature will not function properly when the member ports receive and send PTP messages on different stacked units. Therefore, it is recommended not to enable the PTP feature on a trunk group that exists in different stack units.
