Resolved Issues: 21.2R2
Authentication and Access Control
Unified-access-control (UAC) authentication might not work post system reboot. PR1585158
Chassis Clustering
Security policies might not be synced to all Packet Forwarding Engines post upgrade. PR1591559
Flow-Based and Packet-Based Processing
Performance degradation might be observed when power-mode-ipsec is enabled. PR1599044
General Routing
SSL-FP Logging for non SNI session. PR1442391
Some transmitting packets might get dropped due to the disable-pfe action is not invoked when the fabric self-ping failure is detected. PR1558899
The show pfe statistics traffic command shows wrong output. PR1566065
When using log templates with unified policies, logs were not generated in a predictable manner. A new construct has been added that allows you to define a default log profile (set security log profile name default-profile) that can be used to improve this behavior when multiple log profiles are defined. PR1570105
Changes in SNMP traps configuration and data exported for TWAMP. PR1573169
Traffic is dropped to or through VRRP virtual IP on SRX380 device. PR1581554
The srxpfe process might stop on SRX1500 device. PR1582989
Packet drop or srxpfe core dump might be observed due to Glacis FPGA limitation. PR1583127
Secure Web proxy continue sending DNS query for unresolved DNS entry even after the entry was removed. PR1585542
On SRX Series devices, significant performance improvements for JDPI's micro-application identification were included in this release. PR1585683
On SRX Series devices, the unknown packet-capture functionality will no longer record SSL. UNKNOWN flows by default. This behavior can be changed by enabling the set services application-identification packet-capture ssl-unknown command. Without configuration the ssl-unknown command, the SRX Series devices will only capture flows marked as UNKNOWN or INCONCLUSIVE. PR1587875
IP packets might be dropped on SRX Series devices. PR1588627
The jsqlsyncd process files generation might cause device to panic crash after upgrade. PR1589108
The pass through traffic might fail post reboot when secure web proxy is configured. PR1589957
Traffic loss might be observed for interface configured in subnet 137.63.0.0/16. PR1590040
The REST API does not work for SRX380 devices. PR1590810
The issue (empty feed-name) starts with the hit returned from cache which points to the node with the parameter of feed-ID (2) inconsistent with the feeds-update (when it's 1). As a result the incorrect feed-ID points to the empty entry in the array of the feed-names. PR1591236
J-web deny log nested-application="UNKNOWN" instead of specific application. PR1593560
When combining log profiles and unified policies RT_FLOW_SESSION_DENY logs were not being generated corrected. PR1594587
When JDPI inspection-limits are reached, under certain circumstances, classification details were not propagated to interested Layer-7 Services, such as IDP. PR1595310
Node1 fpc0 (SPM) goes down after ISSU and RG0 failover. PR1595462
Jflow V9 application-id record: Network based application recognition value for IPv4 application-id are not as expected. PR1595787
Delay might be observed between Services Processing Card failing and failover to other node. PR1596118
The flowd process might core dump if application-services security policy is configured. PR1597111
AAMW functions will be bypassed on HTTPs after AppID package upgraded to version 3313 or later. PR1597179
The srxpfe process might crash and generate a core file post "targeted-broadcast forward-only" interface-config commit. PR1597863
The flowd process might generate files if the AppQoS module receiving two packets of a session. PR1597875
The flowd process might stop in AppQoE scenarios. PR1599191
The httpd-gk process might generate core files when IPsec VPN is configured. PR1599398
The CRC/Align errors and Fragment frames seen with traffic against 400G ports. PR1601151
Traffic might be dropped at NAT gateway if EIM is enabled. PR1601890
The flowd process might crash if the DNS-inspection feature is enabled by configuring SMS policy. PR1604773
Memory leak at the useridd process might be observed when Integrated User Firewall is configured. PR1605933
When the tap mode is enabled, the packet on ge-0/0/0 is dropped on RX side. PR1606293
The flowd process might crash if the DNS-inspection feature is enabled within SMS. PR1607251
Enabling dnsf traceoptions on SRX300 line of devices might result in flowd process stop. PR1608669
Enabling security-metadata-streaming-policy might cause Packet Forwarding Engine stop. PR1610260
DNS based SecIntel statistics were not populating correctly on SRX Series devices. PR1611071
Interface might not come up when 10G port is connected to 1G SFP. PR1613475
Enabling security-metadata-streaming DNS policy might cause a dataplane memory leak. PR1613489
On SRX Series devices running DNS Security in secure-wire mode, DGA verdicts would not be returned to the device. PR1616075
Interfaces and Chassis
IPv4 or IPv6 address from the config on the interface might not be applied when the interface is moved from tenants to interface stanza in the configuration. PR1605250
Intrusion Detection and Prevention (IDP)
Custom attack IDP policies might fail to compile. PR1598867
IDP policy compilation is not happening when a commit check is issued prior to a commit. PR1599954
The srxpfe might crash while the IDP security package contains a new detector. PR1601380
This release includes optimizations made to IDP that help improve its performance and behavior under load. PR1601926
High RE CPU usage occurs when routing-instance is configured under security idp security-package hierarchy level. PR1614013
J-Web
The zone information disappears when functional zone is configured. PR1594366
