General Routing

  • On ACX7024 and ACX7100 platforms, the show chassis fpc command should not display temperature, CPU, and memory utilization values. These metrics are not valid for these platforms since FPC(Flexible PIC Concentrator) is a logical FRU (Field Replaceable Unit).PR1735274

  • When ingress policer is configured, to drop ingress traffic, on an interface with upMep the CFM packets generated from the upMep will also be dropped due to the policer. This will lead to CFM session going down.PR1754938

  • On Junos OS Evolved ACX7000 platforms configured with MPLS tunnel and Storm Control, the Layer 2 or MPLS tunnel-terminated known unicast traffic arriving at the ingress interface assigned with a high drop precedence by the interface-level classifier will get dropped on the interface where storm control profile is active. Due to this, MPLS tunnel traffic may get affected.PR1802525

  • On all Junos OS Evolved platforms, MPLS (Multiprotocol Label Switching) payload type ether-pseudowire configured along with any other MPLS payload type does not work as expected and traffic will be impacted.PR1824219

  • On all Junos OS Evolved platforms, host-originated L3 (Layer 3) traffic is marked with DSCP(Differentiated Services Code Point) value 48 [INET 110b] in the IP header, even if class-of-service host-outbound configuration is not present. Host-originated L2 (Layer 2) traffic is marked with IEEE 802.1p value 0 in the header, even if class-of-service host-outbound configuration is not present.PR1837443

  • An LSI IFL remains in RPD even after being deleted by the interface manager daemon. It is visible in show interface routing but not in show interfaces, indicating that RPD still holds the IFL despite its removal elsewhere. rpd-agent does not send a delete message to RPD due to a reference count issue. Another daemon?likely l2ald?still holds a reference to the IFL. rpd-agent only sends the delete once all references are cleared, which doesn't happen in this case. The fix is to send a "delete pending" message from rpd-agent to RPD. RPD will treat this as a delete and remove the IFL, ensuring consistency across the system.PR1866522

  • ACX7100-32C:While Verifying Accounting Flow inline-jflow-error-information of inline-as-lookup-failure is not getting as expected.PR1882224

  • On Junos OS Evolved ACX7024 and ACX7024X, the Active Disk Usage Exceeded alarm is raised and not cleared even if the usage is less than 50%. This issue has no impact on traffic.PR1884419

  • With traffic running and deletion and addtion of fti tunnel multiple times, IPv6 traffic drop is observed in the DUT. PR1896144

  • During the transition from Slave 1 to Slave 2 in AFTS, there is a scenario where Slave 1 gets disabled, but the SPLL information from Slave 2 is received with a delay. As a result, the system initially remains in thePhase Alignedstate (Active, Ready) with Slave 2. Due to the delayed SPLL update, it then shifts to theAcquiringstate (Active, Not Ready) as it begins synchronisation with Slave 2, and then the system successfully re-aligns and returns to thePhase Alignedstate (Active, Ready) with Slave 2.PR1909821
