General Routing

  • On Junos platforms, if you change CCM configuration from aggregated Ethernet logical interface to the physical logical interface in a single commit, you might see cfmd core files in the logs. PR1612212

  • Tx stuck issue might trigger a major alarm DPDK. PR1626562

  • VLAN priority might change at the egress end of the circuit. PR1630255

  • Late drops are not at par with PN configured. PR1630724

  • The ARP request packets might be sent out from ACX router without VLAN header. PR1638421

  • A missing component in the dump kernel might prevent the ACX-710 router from rebooting after generating the file. PR1639459

  • KRT queue entries get stuck during Routing Engine switchover when backup RPD is not yet ready. PR1641297

  • The mcsnoopd crash occurs while adding igmp-snooping. PR1641497

  • Attributes are showing as "Unknown_Attribute" while verifying smartd parameters in ACX5448-M. PR1643542

  • In EVPN multihoming, BUM traffic from the CE device floods back to the CE device. PR1643598

  • Reboot reason is not as expected for ACX5448-M. PR1643781

  • The copper ports on ACX5448 might go down if loaded with copper SFP. PR1643989

  • Traffic drop might be seen on the interfaces that use copper SFP after the reboot. PR1645396

  • The swap-push/pop-swap VLAN map operations on VPLS logical interface might not work. PR1648182

  • While sending BGP NOTIFICATION messages for RFC 8538 HARD RESET, the data portion is sometimes not present. PR1648479

  • If a firewall has a log action and you applied on physical interface or lo0, the LDP cannot go up. PR1648968

  • In the SR-TE scenario, sensors populate incorrectly for colored tunnel BSID routes when you enable uncolored tunnels. PR1665943

  • On ACX710 and ACX5448, its variants Packet Forwarding Engine might crash due to configuration of BFD. PR1667129

  • Shutting the CE interface and bringing back up causes traffic (going toward the core file) drop. PR1667724
