General Routing

  • In a QFX51200-48YM-8C VC setup, after a a primaryship switch over fan tray of linecard might not be displayed in show chassis hardware and show chassis environment. There is no functional impact. PR1758400

  • There exists a hidden CLI upgrade option to do "clean-install". This has been enabled in 23.4R2-S3 and Mainline from 25.1R1 onwards. Using CLI upgrade with this option will do a "nist" compliant secure-erase for SATA disks. This method of CLI upgrade needs to be used with caution since this will wipe clean all configs/logs/files on the SATA FS and re-install the image.PR1847058

  • There is an inconsistency in the way auto channelization works. Based on the peer status it might split up unexpectedly. So for configuration which requires a specific speed/channelization we recommend setting the port manually. PR1852964

  • A memory corruption issue can result random dcpfe (dense concentrator packet forwarding engine) process crashes on all Junos QFX and EX platforms configured with VXLAN (Virtual Extensible Local Area Network) configuration. PR1856424

  • On QFX10K2-60C switches, if traffic is coming from MPLS and going towards EVPN VXLAN tunnel (problem with the next-hop via ARP/IPV6 NDP to reach final destination IP) then traffic drop will be seen. PR1861501

  • On QFX10002-60C platforms when ECMP is required to get multiple-path to multiple hosts connected, and with IPV6 address configured as a destination address, the destination MAC rewrite process fails, due to the unilist nexthop for IPv6 destination is getting overwritten. This leads the IPv6 packets to the host, to get dropped over the ECMP routes. PR1865354
