General Routing

  • On the EX9214 device, if the MACsec-enabled link flaps after reboot, the error "errorlib_set_error_log(): err_id(-1718026239)" is observed. PR1448368

  • A delay of 35 seconds is added in reboot time in Junos OS Release 20.2R1 compared to Junos OS Release 19.4R2. PR1514364

  • Traffic does not get load balanced by EX4300-VC platforms over ESI links with EVPN_VXLAN configured. PR1550305

  • "Cattle-Prod Daemon received unknown trigger (type Semaphore, id 1)" error messages seen on the VTY when we issue CLI commands to fetch host route scale. No functionality impact seen during the same. PR1554140

  • "Resource deadlock avoided" messages are observed during software add on EX4400. No functionality impact seen. PR1557468

  • When dot1x server-fail-voip vlan-name is configured, ensure that both server-fail-voip vlan-name and voip vlan are configured using vlan-name and not by using vlan-id. PR1561323

  • RPD core file is generated when the device reboots and daemon restarts. Daemon recovers and there is no service impact on routing protocol usage. PR1567043

  • When a MACsec session is down and the physical interface is up, traffic might continue to pass over the interface unencrypted. PR1569650

  • Below is the status of management LED when speed is set to: 1. 10m - Activity LED is not blinking when ping/traffic is runnig (instead it is remaining steady GREEN) 2. 100m - Activity LED is blinking without any ping/traffic. PR1573889

Infrastructure

  • On EX Series switches, If you are configuring a large-scale number of firewall filters on some interfaces, the FPC might crash and generate core files. PR1434927

  • "IFDE: Null uint32 set vector, ifd and IFFPC: 'IFD Ether uint32 set' (opcode 151) error message is observed continuously in AD with base configurations. PR1485038

Layer 2 Features

  • The memory leak might happen due to eswd daemon on EX Series platforms. A message like the following is displayed in the system log: eswd[1330]: JTASK_OS_MEMHIGH: Using 212353 KB of memory, 158 percent of available /kernel: KERNEL_MEMORY_CRITICAL: System low on free memory, notifying init (#2). /kernel: Process (1254,eswd) has exceeded 85% of RLIMIT_DATA: used 114700 KB Max 131072 KB. PR1262563

Platform and Infrastructure

  • Upgrading satellite devices might lead to some SDs in SyncWait state. Cascade port flap is not causing the issue. PR1556850

  • On all EX9200 line of switches with EVPN-VXLAN configured, the next-hop memory leak in Trio ASIC happens whenever there is a route churn for remote MAC-IP entries learned bound to the IRB interface in EVPN-VXLAN routing-instance. When the ASIC's NH memory partition exhausted the FPC might reboot. PR1571439

Routing Policy and Firewall Filters

  • On all Junos OS platforms with "set policy-options rtf-prefix-list" configured, if you upgrade to a specific version, the device might fail to validate its configuration, which eventually causes the rpd to crash unexpectedly due to a software fault. PR1538172
