PR Number Synopsis Category: DC PFE QoS
1466770 Slow packet drops might be seen on QFX5000 platforms
Product-Group=junos
The issue observed on QFX5000 platforms when there are any packets on the port before its buffer configuration is completed after the reboot. This issue is very rare and the window could be just few milli seconds.
PR Number Synopsis Category: DHCP related Issues

PR Number Synopsis Category: QFX PFE L2
1462171 The LLDP function might fail when a Juniper device connects to a non-Juniper one
Product-Group=junos
On EX/QFX platforms with STP disabled, the LLDP function might fail when a Juniper device connects to a non-Juniper one. In this scenario, the LLDP PDU with destination MAC 01:80:c2:00:00:00, which is one of the three reserved MAC addresses for LLDP in IEEE 802.1AB, will be ignored by Juniper LLDP process, and this causes the LLDP function failure. This issue has service impact.
1467466 Few MAC addresses might be missing from MAC table in software on QFX5k platform.
Product-Group=junos
On QFX5k platform, if Packet Forwarding Engine process is restarted manually or device reboot occurs, some MAC address(es) might not be seen on software MAC table but MAC address will be present in hardware table.
1469596 Ingress traffic might be blackholed if underlying interfaces flap in EVPN/VXLAN scenario
Product-Group=junos
On QFX5000 platforms with Ethernet Virtual Private Network (EVPN) and Virtual Extensible LAN (VXLAN) scenario, if there is the underlying interface flaps for the core network side, all the ingress traffic might be backholed by the VXLAN Tunnel Endpoint (VTEP) due to this issue.
PR Number Synopsis Category: QFX L3 data-plane/forwarding
1455547 The coredump might occur during adding/removing EVPN Type-5 routing instance
Product-Group=junos
On QFX platforms, the coredump might occur during adding/removing EVPN Type-5 routing instance. The EVPN route would be corrupted and traffic/service impact appears if hitting the issue.
1463092 When deleting IRB on the layer 3 gateway, IRB does not get removed from PFE and will blackhole traffic to IRB mac address
Product-Group=junos
On QFX5110/5120 platform as the layer 3 gateway, after deleting the configuration of interfaces irb, The IRB might not get removed from PFE and will blackhole traffic to the MAC address of the deleted IRB.
1475819 Traffic might not be forwarded over ECMP link in EVPN VXLAN scenario
Product-Group=junosvae
On QFX5110/QFX5120 platforms, when Traffic Load Balance is used in EVPN VXLAN scenario, traffic might not be forwarded over ECMP link after the ECMP link flapped.
1477073 GRE transit traffic does not forward in VRRP scenario
Product-Group=junos
On QFX5110 platforms, GRE transit traffic might be dropped when sending GRE tunnel packets with the destination MAC as VRRP MAC. It has a traffic impact.
PR Number Synopsis Category: QFX PFE MPLS
1477301 The traffic may be lost over QFX5100 switch acting as a transit PHP node in the MPLS network
Product-Group=junos
In the MPLS network, the packets may get dropped by egress node if the packets go through the QFX5100 switch acting as a transit PHP (penultimate-hop popping) node.
PR Number Synopsis Category: BBE Autoconfigured DVLAN related issues
1467468 L2 Wholesale not forwarding all client requests with stacked VLAN
Product-Group=junos
In the Non-ANCP Based L2 Wholesale scenario, if more than one request packets from customer side encapsulated in dual-tagged VLAN arrive at PE device, only the first one of the packets which share the same outer VLAN gets forwarded, and the rest will fail.
PR Number Synopsis Category: Border Gateway Protocol
1487691 High CPU utilization might be observed when the outgoing BGP updates are sending slowly
Product-Group=junos
On all Junos platforms with the BGP routing protocols, the rpd process might go into a high CPU utilization causing slow network convergence. If a BGP peer is receiving and processing BGP updates slowly, this may cause the BGP output queue of the sending BGP peer to be full. When the queue is full it causes high CPU utilization of the BGP IO thread (bgpio, it is part of the rpd daemon) on the sending BGP peer. This defect could cause network-wide slow BGP network convergence. (See also https://kb.juniper.net/TSB17725)

PR Number Synopsis Category: MX10K platform
1471372 Sudden FPC shutdown due to hardware failure or ungraceful removal of line card may cause major alarms on other FPCs in the system
Product-Group=junos
On the MX10008/MX10016 platforms, If the FPC line card gets offline due to power failure or FPC Line card is removed from the chassis without prior offline of the card, other FPC line cards in the system will report fabric failures and fabric self-ping failures. The fabric self-ping failure will invoke disable-pfe action. Once PFE is disabled due to disable-pfe action, the line card needs to get restarted to recover. This issue will cause traffic loss.
PR Number Synopsis Category: FreeBSD Kernel Infrastructure

1466810 EPR iCRC errors in QFX10000 series platforms might cause protocols down
Product-Group=junos
EPR iCRC errors in QFX10000 series platforms might cause protocols down. FPC will be in wedged state and will not pass traffic on that PFE if hitting this issue. EPR iCRC errors are normal and caused by transient hardware conditions. EPR iCRC errors are not expected to impact the protocols, and only one CRC failed packet will be dropped. But due to incorrect handling of this error, it affects protocols and causes FPC wedge.
