PTP feature stops working

• PTP boundary clock can be in any state [PHASE ALIGNED/HOLDOVER/FREE RUN].
• Boundary clock stops providing PTP clock downstream causing clients get disconnect or go out of phase aligned

The issue is due to below ;

FPC0(LAB vty)# show ptp cse-status  
PPE CSR Config (0x0018) : 0x00080000
CSE Config    (0x01c0) : 0x000000A9
CSE Status    (0x004c) : 0x000004A0
        CSE DCM lock lost counter[0:3] : 0x0
        CSE DCM lock sync signal[5:4] : 0x2
        CSE DCM lock[6]               : 0x0 
        Hybrid DCM lock[7]            : 0x0 
        PTP DCM lock[8]               : 0x0 

If we have any of the CSE DCM Lock/ Hybrid DCM Lock/PTP DCM Lock does not get set, this implies that it is running into an Hardware issue and we need to replace.

Right value to be seen for below command is ;

FPC0(LAB vty)# show ptp cse-status  
PPE CSR Config (0x0018) : 0x00080000
CSE Config    (0x01c0) : 0x000000A9
CSE Status    (0x004c) : 0x000004A0
        CSE DCM lock lost counter[0:3] : 0x0
        CSE DCM lock sync signal[5:4] : 0x3
        CSE DCM lock[6]               : 0x1 
        Hybrid DCM lock[7]            : 0x1 
        PTP DCM lock[8]               : 0x1 
 

We need to replace the device to recover.
