General Routing
Issue occurs only when the routing daemon crashes but does not impact on rest of the NSR support. PR1561059
On PTX10001-36MR, the software driver reads the voltage threshold erroneously causing the
Host 0 Voltage Threshold Crossed
alarm to present on the device. PR1592258Traffic loss observed on BGP-LU paths after restoring primary paths in setup with IGP/LDP RLFA enabled. PR1619229
400G ZR-M 740-131169 modules does not come up in the odd ports due to crossing temperature threshold, which results into optics shutdown. Manually configuring fan speeds to 100 percent does help in bringing the optics up. PR1631279
System reboot or boot up with traffic might result in init time fabric link crc errors and cause traffic drop. PR1635178
The 400G-ZR/400G-ZR-M optic transceiver firmware upgrade failures. It is a generic issue faced across all single RU platforms supporting QDD-400G-ZR/QDD-400G-ZR-M. PR1638284
The next-header match in IPv6 firewall filter does not work as expected. The next-header matches the payload-protocol (last-header). PR1645401
Sflow cannot populate extended router header or true OIF for packet traversing through ECMP in TEVRF or recovery VRF. PR1652202
Junos OS Evolved does not support the following RPC:
content_copy zoom_out_map// KillProcess kills an OS process and optionally restarts it. rpc KillProcess(KillProcessRequest) returns (KillProcessResponse) {}
Junos OS Evolved does not support the mpls-any and mpls-inet-both-non-vpn multiple rewrite rules aggregated Ethernet on PTX devices running BT ASIC. The order of applying the rewrite rules is not correct. The non-VPN rewrite rule gets effect for the VPN traffic. PR1655653
On adding filter to loopback interface, at times incorrect count gets displayed for the firewall policer. You must clear all firewall. PR1664600
Junos OS Evolved does not support the GNOI API SetPackage through Remote Download. PR1665185
Sometimes BGP and RSVP sessions remain down after quick arpd process disable and enable. Whenever you encounter such scenario, system can be recovered from erroneous state by executing
restart routing
gracefully in CLI. PR1665362On restarting the msvscd application, data does not get exported through the UDP query. PR1670826
Junos OS Evolved supports mfg-name only for optics where those FRUs can be from different manufacturers. All other FRUs manufactured by Juniper do not stream mfg-name. PR1672697
Fragmented packets have an additional next hop (frag) that causes the FLT to not match on ICMPv6 headers for lo0 filters. You must change the loopback MTU size. PR1675820
Log clean-up process does not cover the Zookeeper log on PTX Series device running Junos OS Evolved and it could potentially cause impact to the system when the log file size occupies too much disk size. Manually cleaning up the log is required. PR1678880
For PTX10001-36MR,
show system applications error
command is not available. PR1682045On Junos OS Evolved PTX Series device, application ZTP fails on node Re0 about one day later post system zeroize. PR1683964
Infrastructure
The GRES triggered through the
request chassis routing-engine master switch
generates the following connector driver overlay messages:{master} root@bowmore-05-re0> [ 1185.081257] gpio-jnx-i2cs gpio-jnx-i2cs.50: Asserting power_status irq 59 [ 1185.125182] OF: overlay: overlay_is_topmost: #9 clashes #10 @/ftc0/i2c-bus/i2cs@54/fan_hwmon [ 1185.125183] OF: overlay: overlay #9 is not topmost
PR1539232On all Junos Evolved OS platforms, the device might panic with vmcore under high memory pressure situations when kernel memory allocation fails. PR1646610
Interfaces and Chassis
You must perform joji over the interface using
test picd optics fpc_slot <fpc slot> pic_slot <pic slot> port <port num> cmd oir_enable test picd optics fpc_slot <fpc slot> pic_slot <pic slot> port <port num> cmd remove test picd optics fpc_slot <fpc slot> pic_slot <pic slot> port <port num> cmd insert test picd optics fpc_slot <fpc slot> pic_slot <pic slot> port <port num> cmd oir_disable
command. PR1646915
MPLS
Traceroute in MPLS OAM on SR over IPv6 might fail in ECMP incase PTX box is in topology. This occurs because of Linux kernel in the Junos OS Evolved puts an autoflowlabel on every IPv6 packet. This flow label is transparent to daemon process, which uses a null value for it and calculates the next hop details. Packet Forwarding Engine however takes the flow label into account and calculates the next hop details. This difference in calculation of next hop details leads to a mismatch in the path the packet takes to the destination and can cause traceroute to fail. PR1618406
When the bypass host route was deprecated, bypass label information does not correctly set when you send the backup PathTear messages if long refresh interval gets disabled between the Point of Local Repair (PLR) and the Merge Point (MP). PR1685182
Network Management and Monitoring
When you configure the
maximum-password-length
command and tries to configure password whose length exceeds the configured maximum-password-length, error messgae gets generated along witherror '(ok/)' tag
gets emitted. Ideally'ok/>' tag
should not be emitted in an error scenario and the configuration does not get committed. PR1585855The mgd process crashes when you configure an invalid value for the identityref type leafs/leaf-lists while you configure openconfig or any other third-party YANG. Issue occurs with JSON and XML loads. PR1615773
Routing Policy and Firewall Filters
On Junos OS Evolved platforms, the unsupported configuration of BGP flow spec
interface-group exclude
might lead to some errors and the Packet Forwarding Engine corruption, which does not permit filter bind. PR1639391
Routing Protocols
When l2cpd (in the context of xSTP) clears the entries that it has programmed on ppmd, that is, when you delete xSTP configurations from the device, there can be a possibility of ppmd core file generation. If ppmd is in distributed mode then there is no service impact, else there can be service impact as packet transmission for various protocols happens if ppmd is in centralized mode. PR1660299
User Interface and Configuration
When you terminate the evo-cda-bt process, fpc gets restarted. We might see agentd crash due to ungraceful FPC restarts. This issue is not seen in a normal working scenario and is seen only upon ungraceful fpc restarts. PR1655441
The system might ask for your password when you are trying to save configuration file. PR1665008
