General Routing

  • When ingress policer is configured, to drop ingress traffic, on an interface with upMep the CFM packets generated from the upMep is also dropped due to the policer. This leads to CFM session going down.PR1754938

  • When DHCP trace options are enabled, there is a possibility that jdhcpd could generate a core file. In general, traceoptions should be enabled only for debugging. They should be disabled once debugging is done.PR1771121

  • This is day-1 issue of Juniper Networks server. It exists on all ACX Series platforms where Juniper Networks server runs. Once the asymmetry configured at slave port, the error propagated to the down stream eventually causes performance issue of spike. PR1793926

  • The application rpd-agent might restart with a core file after interface related event changes. This issue is likely to occur when the interfaces are activated/deactivated/created/deleted. This could be due to

    • Bulk change in interface configuration or

    • Admin-initiated application restart through command request system application node re0 restart app <application>

    • System triggered automatic application restart due to internal events.

    Note: This issue occurs due to very rare combination of events and is not seen in most use cases. There is no service impact when the issue occurs, and router operations are unaffected.
