Forwarding and Sampling

  • On Junos Evolved PTX Series devices, next-hop churn, such as adding and deleting routes, can lead to the exhaustion of available pfetokens. These tokens are claimed but not released, which causes low pfetoken availability. This issue results in traffic drops and unexpected system behaviour.PR1833330

General Routing

  • On all EVO platforms, port LED goes unlit/off instead of amber/on when port is disabled. PR1690655

  • On all Junos OS Evolved platforms, snmp mib walk jnxOperatingState on Fan Tray X returns running(2), although fan tray X speed is set to full-speed. It is expected runningAtFullSpeed(5) when fan tray speed is set to full-speed.PR1701983

  • DNS resolution over a routing-instance fails.PR1733616

  • When DHCP trace options are enabled, the jdhcpd might create a core file. In general, traceoptions must be enabled for debugging only. They should be disabled once debugging is complete.PR1771121

  • On Junos OS Evolved PTX Series platform, the BGP session flap can be seen when inline Bidirectional Forwarding Detection (BFD) is configured under routing instance without loopback interface (lo0) leading to partial traffic drop. The issue is seen only when the interface is within the routing-instance.PR1811245

  • On Junos Evolved PTX10003 platform the command indirect-next-hop-change-acknowledgements is required in the Junos default configuration. If the command is missing, it will result in packet loss.PR1836337

  • On PTX10004, PTX10008, and PTX100016 platforms with LC1202 line card, retimer/gearbox ports on LC1202 line card take longer duration (approximately 1500 msec) to bring an interface back up after short LOS insertion from peer device. This breaks sub-second hold-time down feature. The code fix enabled 'fast linkup' feature of retimer/gearbox ports. It helped the link to come up faster. Ideally retimer/gearbox ports take 1.5 sec to come up, but with this feature, links come up in 1 sec. PR1846379

Network Management and Monitoring

  • Error message "CMDOUT (error: error renaming temp state file /var/lib/logrotate.status.tmp)" is generated every 15 minutes.PR1747722

  • On Junos OS Evolved platforms, SNMP cold start trap is observed on console log upon system reboot, but it is not sent out to external server.PR1788308
