    Known Behavior

    This section lists known behavior, system maximums, and limitations in hardware and software in Junos OS Release 17.3R3 for SRX Series devices.

    For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.


    • On SRX5400, SRX5600, and SRX5800 devices, the CLI hangs while displaying CA profile group. This CA profile group contains CA certificates with 100’s of certificates, and the CLI times out as PKId needs excessive time to handle such requests. Instead of displaying entire CA group, you can display the individual CA profile inside the CA group to avoid this problem. PR1276619

    Chassis Clustering

    • If you enable IP monitoring on the redundancy group when the reth interface has more than one physical interface configured, then IP monitoring might not work properly on the secondary node. This issue occurs because the backup node might send traffic using the MAC address of the lowest port in the bundle. If the reply does not come back on the same physical port, then the internal switch might drop the traffic. PR1344173


    • On SRX Series devices, ESP packet drops in IPsec VPN tunnels with NULL encryption algorithm configuration are observed. PR1329368
