General Routing

  • On Junos Evolved TD4 platform (QFX5130-48CM), intermittent link flaps cause the hardware link scan to malfunction, resulting in incorrect high values in the Correction Field (CF) of Precision Time Protocol (PTP) packets, causing improper timestamping. This impacts system time inaccuracies across the network and the overall timing synchronization of the network until remediated.
