Resolved Issues: 17.1R2
General Routing
The routers equipped with NG-REs might raise memory size mismatch alarm after upgrade. PR1220061
User-configured TPID is not applying on a single-tagged VLAN interface. PR1237687
Junos Telemetry Interface: Frequent disconnects seen in MQTT when IFL sensor is provisioned for longer duration. PR1238803
Tx rate not gauranteed for an extreme case scheduler with traffic from multiple ingress Packet Forwarding Engines to a single egress Packet Forwarding Engine. PR1241291
Add set parameter to CLI request system software add command. PR1246675
"telemetry_start_polling_fd: evSelectFD failed, errno: 9" are continuously seen in log. PR1248813
cs605x_otu_defect_active: cs605x_get_otu_alarms failed. Messages are logged when only the first two ports are not configured on 4x100G OTN PIC. PR1250707
While processing lookup results, IRP block raises an interrupt upon detecting an error condition. The interrupt is active until the trap code error is read. Under certain conditions, software is not reading this trap code error upon IRP interrupt. This causes the following syslog messages:
fpc5 INTR: throttle 60sec PECHIP[2]:pe.irp.intr.status:ap0_trap(0): (Count:1)
fpc5 INTR: throttle 3630sec PECHIP[2]:pe.irp.intr.status:ap0_trap(0): (Count:3434)
fpc5 INTR: throttle 3600sec PECHIP[2]:pe.irp.intr.status:ap0_trap(0): (Count:6841)
The following log message may be printed frequently during normal operation on backup Routing Engine of PTX5000 router when the Routing Engine type is RE-DUO-C2600. The message is cosmetic and does not indicate any service impact or Routing Engine mastership loss:
/kernel: mastership: sent other Routing Engine mastership loss signal
On a PTX Series platform, if running interfaces on QSFP28 PIC in 10G mode, some of the interfaces on the QSFP28 PIC may not come up after a system reboot or PIC restart. PR1263413
This only affects only PTX5000 and PTX3000 platforms with Third-generation FPCs. Software periodically monitors voltages on the FPCs to check if they are within the proper range. This change adjusts the expected values for voltages on certain power rails of the FPCs. In rare cases it is possible that a marginal FPC was operating inside the older limits but outside the new limits, in which case a new chassis alarm will be raised for that FPC. PR1263675
In PTX routers equipped with Next Generation Routing Engine (RE-S-X6-64G, REMX2K-X8-64G, RE-PTX-X8-64G/CB2-PTX), the following log messages might be displayed as an error messages after a commit command is executed:
sdk-vmmd: %USER-3: is_platform_rainier: Platform found as rainier
Interfaces and Chassis
Configuring ODU FRR related otn-options might crash the FPC without producing a core file. PR1038551
5-port 100G DWDM PIC: Unsupported CFP is initialized even when part number is not valid. PR1174080
MPLS
The RPD might crash while making static LSPs up. PR1084736
RPD crash in MPLS OAM environment. PR1233042
The LDP routes are not installing with matched L-ISIS routes in inet.3 route table. PR1248336
RPD core when rpd is terminating while there are a large number of RSVP LSPs. PR1257367
Platform and Infrastructure
The "rdd" process restarted in get_mview_root( ) during GRPC JVISION activation while chassis PFEs are coming up. PR1225086
mgd might crash after executing command show ephemeral-configuration | display inheritance. PR1258823
Resolved Issues: 17.1R1
Class of Service (CoS)
The error message cos_check_temporal_buffer_status might be observed when configuring hierarchical CoS with strict-high scheduling. PR1238719
General Routing
False login attempts might be seen on MPC7E/8E/9E for receiving noise. PR1234712
NGRE: Routing Engine switchover resulting when trying to connect to FPC through cty. PR1235761
PTX Series router might send wrong packets if MPLS LSPs have protection configured. PR1239634
'oc-path' to be removed from prefix for IFD sensor (both FreeBSD 10.x-based Junos OS and FreeBSD 6.1-based Junos OS). PR1244658
Infrastructure
Continuous kernel logs and LDP stats timeout error when executing show ldp traffic-statistics. PR1215452
Interfaces and Chassis
5-port 100G DWDM PIC: chassisd logs are flooded with power related messages. PR1184415
ARP entry learned through Aggregated Ethernet interface does not expire when the ARP IP is no longer reachable. PR1211757
Routing Protocols
The rpd process might crash after performing BGP flapping. PR1222554
An rpd core file could be seen if MPLS goes down. PR1228388
Kernel crashes in the chassis after FPC reset. PR1242362
