General Routing

  • Ungraceful removal (OIR) of FPC or an FPC fault might result in PCIE MAJOR alarm PCI Uncorrected error on dev 0000:00:03.0 which does not get cleared. PR1620197

  • When TCP Main and TCP remain attached together on the physical interface it is observed that improper scheduler MAP gets configured on HQoS physical interface while sched params modification and bind are performed on same commit. This is a sequence issue from CoSD (Routing Engine) which is not guaranteed at Packet Forwarding Engine side. And this is applicable for all platforms.PR1664785

  • The QSFP28-DD-2X100GBASE-LR4 links go down on multiple FPC restarts/system reboots due to the optics tx loss. PR1685520

  • DTE mask fails for cascaded setup with long run.PR1697093

  • In Layer 2 circuit or EVPN or VPLS topology, when the UNI interface has static or dynamic LAG configured, the native LACP packets (untagged PDUs) received in the UNI interface are punted to hostpath as expected. The tagged LACP PDUs received on the same UNI are expected to be transparenly forwarded to the destination like data packets but these are also punted and dropped in the ACX device. The same is applicable for LLDP case too.PR1698549

  • On Junos OS Evolved platforms, any UI (user interface) set (configuration, script, license) changes done post software addition are being lost after the subsequent reboot.PR1699699

  • HwResIdxDnxTrunk index availability is low alarm filed after configuring 255 lag physical interfaces and alarm does not get cleared after removing the configuration.PR1703506

  • Only one virtual-gateway-v4-mac and one virtual-gateway-v6-mac is supported system wide. The IPv4 and IPv6 MAC might be same or different. PR1708967

  • Repeated error log messages indicating duplicate IP, L2ALM_DUPLICATE_IP_ADDR are seen on mclag devices with IPV6 traffic.PR1719868

  • A few macip objects owned by l2ald are not cleaned up post changing the MC-AE mode from active-active to active-standby. So it causes incomplete object state and system. With the above mode change, we see some stale mac-ip entries in the show ethernet-switching mac-ip-table. PR1722626

EVPN

  • On all platforms, MAC-IP route deletion and addition are triggered when re-ARP (Address Resolution Protocol) on MH (Multihoming) device fails in the EVPN-MPLS multihoming scenario resulting in traffic drop.PR1691132

Services Applications

  • Paragon Active Assurance (PAA) plugins might report incorrect latency results occasionally exceeding 20 ms, the error is larger in transmit direction and is more likely to occur at higher rates.PR1697270

User Interface and Configuration

  • The system might ask for your password when you are trying to save configuration file.PR1665008
