Conditions
GPS signal loss in a Cell Site Router NCS540 acting as TGM.
Further Problem Description
When the GPS signal is lost in EGM mode, the PTP goes into holdover state and by default, the clock class is set to 160. When a Samsung RU receives CC 160 it stops all traffic.
In order to prevent that, there is an available holdover configuration for holdover duration, clock class and time trace, which allows to change the clock class to a small value(like 7) during a holdover.
The CLI for holdover is available but is not supported.
In order to implement the holdover commands, the clock should be changed from TGM to TBC and using virutual port config.
