General Routing

  • The ping command on an ACX Series device might show variable latency values. This is expected for host-generated ICMP traffic because of the design of the Packet Forwarding Engine queue polling the packets from ASIC. PR1380145

  • The circuit-cross-connect logs do not compress after rotation. PR1398511

  • The rpd process might crash if the BGP route gets resolved over the same prefix protocol next-hop in the inet.3 table that has both the RSVP and LDP routes. PR1458595

  • On the ACX710 routers, if the console cable is plugged in and the terminal connection is active and is sending characters to the interface, the system boot might be interrupted and the ACX710 boot will be stalled. PR1513553

  • On the ACX710 routers, alarm does not raise while booting the system with the recovery snapshot. PR1517221

  • On the ACX5448 routers, ping stops working even though the ARP entry is present during continuous script executions. PR1533513

  • The MC-LAG ICL interface needs to be configured as an aggregated Ethernet interface. PR1567790

  • On the ACX448 routers, the packet buffer allocation failed messages appears when you scale the CFM sessions with the SLA iterator. PR1574754

  • Micro-bfd session gets stuck in INIT state at ACX7100 when peer router ACX5448 is used. Micro bfd is not qualified with vlan-tagged configuration on ACX5448. PR1574780

  • On ACX5448 platforms, if hierarchical-scheduler is configured for an interface, during an interface flap or configuration changes, some of Packet Forwarding Engine buffers might not synchronize. As a result, packets might drop without congestion. PR1603622

  • When multihop BFD is configured on ACX5448, delegated BFD sessions are not coming up. PR1633395

  • ACX710 MC-LAG non-revertive function is not working as expected. PR1633847

  • Failing to remove USB stick causing installation to start again. As a workaround, USB installation requires a keypress before reboot to enable removal of USB device before system is restarted. PR1640143
