Known Limitations


This section lists the known behaviors, system maximums, and limitations in hardware and software in Junos OS Release 20.2R1 for vSRX.


  • When a dynamic application is created for an edited policy rule, the list of services will be blank when the Services tab is clicked and then the policy grid will be autorefreshed. As a workaround, create a dynamic application as the last action while modifying the policy rule and click the Save button to avoid loss of configuration changes made to the policy rule. PR1460214
