General Routing

  • On Junos Evolved TD4 platform (QFX5130-48CM), intermittent link flaps causing 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.PR1829734

  • On the QFX5230/QFX5240 platforms, host injected control protocol frames are accounted under the egress port's best-effort queue ( Q0 by default) even though they are sent on the network control queue. this is only a display issue of the show command output and does not affect the actual prioritization of traffic.PR1835046

Interfaces and Chassis

  • This is unsupported configuration for channelized interfaces.PR1858941
