General Routing

  • On WRL8 based VMHost platforms (ACX6360), there is no log rotation for resild log and temperature sensor info is incorrectly written into resild log which could result in continuous logs in resild log file. The disk usage might keep increasing due to this issue. The disk usage could be eventually full which could cause system to hang and reboot. PR1480217

  • Due to the BRCM KBP issue, route lookup might fail. PR1533513

  • On the ACX500 devices, service MIC does not work. PR1569103

  • On ACX5448 and ACX710 platforms, all types of delegated BFD sessions configured on routing-instance other than the default routing-instance might not come up.PR1633395

  • Interop for 1G interfaces between EX4100 SKUs and ACX5448/ACX5448-M/D or MX480 does not work. PR1657766

  • For ACX5448 devices, if a non-default ssh port is configured for system login, after upgrade to 21.4 release, the FPC is stuck in offline. To avoid such issue please use default SSH port and use protect Routing Engine filter to only allow the access from the trusted source.PR1660446

  • When TCP Main and TCP remaining attached together on IFD its observed that Improper Scheduler MAP is getting configured on HQoS IFD for some corner scenarios. This is a sequence issue from CoSD(RE) which not guaranteed at Packet Forwarding Engine side. And this applicable for all platforms.PR1664785

  • On ACX5000 devices, in VPLS MH cases, the standby UNI ifl in the backup router gets programmed in the Disable state by adding the UNI interface to invalid the VPN ID in hardware. During switch over, the UNI ifl gets deleted and added under the VPLS instance VPN ID. In issue case, UNI interface added under the invalid VPN ID in the backup router tries to get deleted by passing the VPLS instance VPN ID, causing the issue.PR1665178

  • The Queue statistics might show constant PPS / bps after interface is disabled. The statistics does not increment and remain same when the interface goes down. PR1685344

  • Reserved buffers might be shown as 0. But internally reserved buffers do get used to queue and transmit traffic on the queue. PR1689183

  • The aggregate Ethernet statistics might show 0 bps for output traffic. It is a CLI output display issue. It does not impact the traffic output. PR1689185

  • dc-pfe: HEAP malloc(0) detected! when a VPLS instance is deactivated in ACX5048. PR1692400

  • Convergance time can be more than 60ms for OSPF TILFA Node protection testing.PR1695292

Routing Protocols

  • SRTE secondary LSP should be only standby in forwarding table, however, it is also active and forwarding traffic due to the wrong metric calculation.PR1696598
