Description

This article provides information about the clksync_ptp_apply_gcfg syslog messages upon configuration commit. These messages are used by Juniper Engineers for debugging purposes and has no impact on service.

Symptoms

The Clock Synchronization Process checks all FPC status upon any interface configuration changes such as add or delete. PTP (Precision Time Protocol) related messages are generated regardless if you have PTP configured on the router.

Snippet of log message: 

fpc0 Posting op 1 for PTP global gencfg arg 0x4c677240 flg 0x0
fpc0 Processing op 1 for PTP global gencfg arg 0x4c677240 flg 0x1
fpc0 clksync_ptp_apply_gcfg: Catastrophic Flag Status, Global: 0, Slave: 0, Master: 0
fpc0 clksync_ptp_apply_gcfg: Freq-only mode is disabled

Some of the MPC cards may generate similar messages as shown above.
