General Routing

  • The cfmd process might generate core files in the logs if you configure the CCM configuration from the aggregated Ethernet interface IFL to the physical IFL in a single commit. PR1612212

  • Multicast traffic drop might be seen if you enable the IGMP snooping for VLAN. PR1628600

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

  • On ACX710 and ACX5448 devices, a PE device stops forwarding Layer 3 VPN traffic after core-facing link flaps. PR1635801

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

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

  • On ACX5448 devices, high priority packets might be dropped. PR1642187

  • On ACX5448 devices, attributes gets displayed as Unknown_Attribute while verifying smartd parameters. PR1643542

  • On ACX5448 devices, reboot reason is not as expected. PR1643781

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

  • Traffic might silently get discarded in the MPLS scenario with explicit-null. PR1646097

  • The swap-pus or pop-swap VLAN map operations on VPLS IFL might not work. PR1648182

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

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

  • The BGP Sensor /bgp-rib/afi-safis/afi-safi/ipv4-unicast/loc-rib/ are not available as a periodic sensor. PR1649529

  • Due to the MAC learning limit being exceeded traffic drop might be observed in the MC-AE scenario. PR1653926

  • The LDP sessions might flap in the VPLS scenario resulting in Packet Forwarding Engine errors. PR1654172

  • The l2circuit backup might not get reverted to primary in rare condition. PR1661802

  • On ACX5448 and ACX710 devices, the transit traffic drops for BGP-LU (Border Gateway Protocol-Labeled Unicast) prefix when the BGP-LU label routes has ECMP (Equal-Cost Multipath) forwarding path. PR1663563

  • On ACX710 devices, the following log related to resources gets reported after you deactivate or activate EVPN RI multiple times : ACX_BD_ERR: dnx_bd_alloc_l2_svlan: System reached L3 IFL and BD limit(12286) PR1670683

  • RIB and PFEs gets out of synchronization due to a memory leak caused by interface flaps or route churn. PR1642172

  • Traffic might drop on the interfaces using copper SFP after reboot. PR1645396

  • HTTP(S) file download becomes nonresponsive over EVPN-ETREE. PR1653531

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

Network Management and Monitoring

  • The snmpd process might generate core files with the filter-duplicates configuration. PR1669510

Platform and Infrastructure

Routing Protocols

  • IPv6 Inline BFD sessions goes down when neighbor does not get resolved. PR1650677
