On Junos QFX10000 devices, file permissions might be changed for /var/db/scripts files after rebooting the device. This issue might have an impact on the scripts running on the box. PR1583839

On the QFX5000 devices, the dcpfe process might crash. PR1588704

On QFX series, switches with the vendor chip as Packet Forwarding Engine, if IS-IS is enabled on an integrated routing and bridging (IRB) interface and the maximum transmission unit (MTU) size of the IRB interface is configured with a value great than 1496 bytes, the IS-IS hello (IIH) PDUs with jumbo frame size (i.e., great than 1496 bytes) might be dropped and not sent to the IS-IS neighbors. The following is the product list of QFX series switches with vendor chip as Packet Forwarding Engine. QFX3500/QFX3600/QFX5100/QFX5110/QFX5120/QFX5130/QFX5200/QFX5210/QFX5220 PR1595823

Pim VXLAN does not work on the TD3 chipsets that enables the VXLAN flexflow.PR1597276

The convergence time degradation is seen in IS-ISv6, OSPFv2, and OSPFv3 when comparing convergence time with Junos OS Release 21.1R1.5. As it is a convergence time issue, many components are involved and hence need investigation of rpd, kernel, and Packet Forwarding Engine. PR1602334

On QFX5100 devices, optical power is seen after detached and attached QSFP on disable interface. PR1606003

On the QFX10002-72q devices, the sFlow samples do not get generated for the transit MPLS traffic carrying IPv6..PR1607497

On the QFX10002-60C devices, the output-mac-control-frames and output-mac-pause-frames counters do not increase. PR1610745

On the QFX5100 Virtual Chassis, traffic loss occurs while testing the 118 aggregate Ethernet groups. PR1611162

On the QFX10002, QFX10008, and QFX10016 devices, on scaling more than 80,000 ARP/NDP, the prds_jpf_nh_token_change: Token change failed for rnh error messages gets generated. PR1616224

When the IFA2.0 init feature enabled on switch and flows are sampled, incorrect pps and bps statistics displayed at the logical child interface level on the ingress and egress ports. PR1620139

The led port init was done for SXE port. PR1621630

Secondary FPC lose their connection to the primary when new members are added to the Virtual Chassis Fabric (VCF). PR1634533

On all QFX Series devices, when any firewall filter is configured with action as sample and accept, and applied on the Integrated Routing and Bridging (IRB) interface. Then the firewall filter might drop all the inbound traffic.PR1646740

On Junos devices QFX5100, QFX5110, and QFX5200, when the device is rebooted or the dcpfe process gets restarted with the local-bias configuration statement enabled on the aggregate Ethernet interface, then the local-bias on the aggregate Ethernet interface does not work as expected. This impacts traffic utilization on the device as the Virtual Chassis (VC) ports might still carry traffic even when the local-bias is configured.PR1651151

On QFX Series platforms, IPv6 traffic output byte (ipv6-transit-statistics) might not be in expected range as per traffic generator statistics. PR1653671

On the QFX5120 devices, multiple mclag-cfgchkd process generates core files after loading the recent operating system. PR1599025

The DHCP client configuration is coming from two places, that is, AIU script and VSDK sandbox. The DHCP client configuration coming from AIU script has the serial ID in vendor ID where as the default configuration from sandbox doesn't have it. There is no impact on functionality or service. PR1601504

Adding one more sub-interface logical interface to an existing interface causes 20 to 50 milliseconds traffic drop on the existing logical interface. PR1367488
