What's New

 

Learn about new features and enhancements to existing features introduced in Junos OS Release 20.2R1 for vSRX and vSRX 3.0.

For more information see Overview of the available virtual SRX models, vSRX and vSRX 3.0.

Interfaces and Chassis

  • TAP mode support (vSRX 3.0)—Starting in Junos OS Release 20.2R1, vSRX 3.0 supports TAP mode for security flow sessions to generate security log information and to display the information on threats detected, application usage, and user details according to the incoming traffic.

    Use the set security forwarding-options mode tap interface <interface-name> command to configure TAP mode on an interface. For inspecting IP-IP and GRE inner tunnel traffic use the set security forwarding-options mode tap inspect-pass-through-tunnel ipip and set security forwarding-options mode tap inspect-pass-through-tunnel gre commands, respectively.

    To disable this TAP mode, delete the TAP mode for the related interface and the related zone and policy configuration of that interface.

    [See TAP Mode for Flow Sessions, TAP Mode for Security Zones and Policies, and forwarding-options (Security).]

Management and Automation

  • VMware Tools support for VMware Hypervisors (vSRX 3.0)—Starting in Junos OS Release 20.2R1, vSRX 3.0 on VMware Hypervisors supports Open VM Tools version 10.3.0 for autoconfiguration. The Open VM Tools are initialized when the guest operating system starts. The service passes information between the host and guest operating systems for better management and operation.
