Resolved Issues: 21.2R3

General Routing

  • On ACX5448 BFD session status is in INIT state, after system reboot. It is seen when we have both CFM and BFD configured on the system. PR1552235

  • Unknown SMART attributes for StorFly VSFBM8CC200G SSD might be seen on MX10008/MX10016/PTX10008/PTX10016 with JNP10K-RE1. PR1598566

  • On ACX5448 routers, CFM does not appear to be in the Ok state after the router reboots. PR1602489

  • On ACX5096 routers, the pps traffic output appears on the deactivated interfaces. PR1608827

  • On ACX710 routers running Junos OS Release 21.2R1 and later might experience kernel crash. PR1608852

  • On ACX5448 and ACX710 routers, traffic towards the CE device through the default route might be dropped in VRF. PR1611651

  • The maximum entry for ECMP is 4096. If all this is used up due to this stale entries, new ECMP entries cannot be created. Therefore, traffic drop will be seen on ACX5448 and ACX710 PR1612026

  • The routing protocol engine CPU is getting stuck at 100 percent. PR1612387

  • The transit traffic might be impacted on PTP scenario. PR1612429

  • Packet fragmentation might be seen when MTU is configured for logical interface. PR1614449

  • On ACX5448 routers, a warning message: "CHASSISD_GENERIC_WARNING: cfg_ddl_handle_rio_pfe_dfw_profile: New firewall profile configured" is observed. As a workaround, restart the Packet Forwarding Engine. PR1614512

  • On ACX5448 routers, there might be mismatches in statistics at rates above 4GB between the physical and logical interfaces. PR1614550

  • When configuring vlan-id-range/list for an aggregated Ethernet interface of layer 2 circuit, the traffic forwarding is only seen for the first VLAN. PR1616147

  • Traffic might not be forwarded after failover in L2 circuit hot standby mode. PR1616892

  • The PFE daemon crash occurs if the standby interface is disabled in the Layer 2 circuit pseudowire redundancy scenario on ACX710 and ACX5448 platforms. PR1617287

  • Host-outbound-traffic might be placed in incorrect queue. PR1619174

  • Traffic might get equally load-balanced irrespective of the scheduler configuration. PR1620137

  • IGMP: 6-8 seconds delay noticed is seen when the receiver switches in between groups. PR1620685

  • Traffic does not get forwarded to one of the the single-homed PE device after you change the VLAN-ID under the routing instance. PR1621036

  • On ACX5448 and ACX710 routers with Layer 3 VPN scenarios, error messages might be generated after multiple core link or protocol flaps. PR1621425

  • The jnxDomCurrentAlarms value is incorrectly set which might indicate a temperature alarm. PR1621894

  • On ACX5448 routers, the smartd configurations do not get applied. PR1623359

  • COS - EXP rewrite is not working in l3vpn scenario when mf filter is configured. PR1623922

  • On ACX5000 local fault and remote fault signaling is not logged on /var/log/ messages. PR1624761

  • Unicast packet loss might be observed due to control-word configuration. PR1626058

  • VPLS traffic loss might be observed post route flap. PR1626267

  • Packet Forwarding Engine might crash after device reboot or Packet Forwarding Engine restarts. PR1626503

  • Output packet statistics are not incremented on the unit even after configuring statistics. PR1627040

  • igmp-snooping configuration is dropping l2vpn multicast traffic on ACX Series platform. PR1628600

  • ACX5048 filters reporting TCAM errors are not installed in hardware after the upgrade from Junos OS Release 17.4R2-S8 to Junos OS Release 20.4R3. PR1630280

  • ACX710 running G.8275.2 stuck at PTP acquiring state if the connection is through some timing unaware nodes. PR1632761

  • Speed 10m configuration error on ACX5048 and ACX5096 routers. PR1633226

  • The storm-control rate-limit might not work with VPLS policer under logical interfaces. PR1633427

  • DHCP clients might not come online for IRB+VLAN/EVPN scenario. PR1633778

  • IS-IS last transition time never increments. PR1634747

  • IPv6 BFD session over aggregated Ethernet might stay down on ACX5448 and ACX710 routers. PR1635020

  • The LACP delay might be observed with an "aggregate wait time" of more than 1 second. PR1635763

  • ACX710 and ACX5448 working as PE stops forwarding L3VPN traffic after core-facing link flap. PR1635801

  • ACX5448 PEM overload alarm threshold is incorrect. PR1636222

  • Locally switched traffic might be dropped on ACX5448 with ESI configured. PR1638386
