General Routing

  • JDI-RCT:ACX : Syslog error @Err] dnx_rt_vswitch_cross_connect_add_del: dnx_rt_vswitch_cross_connect_add_del:cross-connect delete failed for IFL 135(UNI 1149255708,NNI 402657548) (-1:Internal. PR1732448

  • On ACX1000/2000/3000 platforms, MPLS load-balancing on AE (Aggregated Ethernet) interfaces with more than one member link may not work as expected after upgrading Junos to 20.1R1 or later releases. PR1739480

  • When restart chassis-control trigged on M/MX router has configuration with ccc instance, syslog is error out " Err] ACX_ASIC_PROGRAMMING_ERROR: pfe_dnx_translation_set: Error, bcm_vlan_port_translation_set rv:Entry not found ".PR1764966

  • On ACX5048and ACX5096 platform, after the device is upgraded, disabling an interface and then rebooting the device will cause a critical issue. All interfaces will go down, resulting in a complete traffic drop. There is no known workaround to prevent this service interruption during the upgrade process. PR1786687

  • ACX1100 PTP(enterprise profile) is stuck at freerun state after upgrading junos to 21.2R3. PR1789694

  • When ACX2200 deploys l2circuit with hot-standby mode, it fails to forward the traffic after a few rounds of consecutive neighbor failover and link cutover. Standby mode does not have such problem. PR1797017

  • ACX710 does not recognize GPON OLT 740-124448 reports NON-JNPR after ACX power cycle. The same error state NON-JNPR can be observed when GPON OLT SFP is installed into ACX router. PR1801112

  • Multicast route is reset every 5 mins with igmp receiver on acx2200 with small traffic loss. Multicast route that are not active would get reset after 5 minutes due to cahce timeout. This was happening even for active routes that had traffic. PR1805017

  • On ACX2200, when interfacing with ACX7024 port will be down if a 10-Gigabit Ethernet port is set to operate at 1G speed. It will impact the services due to interface down. PR1807801

  • On ACX2200 series, ge (gigabit ethernet) interfaces configured for PTP (Precision Time Protocol), after PTP is deactivated and activated or activated for the first time, traffic can experience packet drops. PR1811850

Junos XML API and Scripting

  • On all Junos platforms where snapshot is supported, when a device is rebooted from recovery mode it fails to commit configuration due to problems with slax import and device might go into amnesiac mode due commit fail. PR1717425

Network Management and Monitoring

  • Issue: Multiple traps are generated for single event, when more target-addresses are configed in case of INFORM async notifications Cause: INFORM type of async notification handling requires SNMP agent running on router to send a Inform-Request to the NMS and when NMS sends back a get-response PDU, this need to be handled. In this issue state, when more than one target-address(NMS IP) is configured for a SNMP v3 INFORM set of configuration, when Get-Response comes out of order in which the Inform-Request is sent, the PDU is not handled correctly causing snmp agent to retry the Inform-request. This was shown as multiple traps at the NMS side. Work-around: For this issue would be to use 'trap' instead of 'inform' in the "set snmp v3 notify NOTIFY_NAME type inform" CLI configuration.
