  • Increased interface support for AWS instances (vSRX 3.0)—Starting with Junos OS Release 22.4R1, vSRX 3.0 supports c5n.18XL Amazon Web Services (AWS) instance types for AWS deployments. With this support, you can run vSRX on up to 36 virtual CPUs (vCPUs) and support 16 interfaces.

    [See Requirements for vSRX on AWS.]

  • Support for TLS-Hello in Traffic Load Balancer (MX240, MX480, and MX960)—Starting in Junos OS Release 22.4R1, we've enhanced Traffic Load Balancer (TLB) to support TLS-Hello, a new health-check type. We've added a CLI knob in the network monitoring profile and you can use his knob to configure TLS-Hello probing type.

    TLS v1.2 and v1.3 health checks are supported for TLS-Hello over TCP.

  • Support for 1-Gbps speed on SRX5K-IOC4-10G card (SRX5400, SRX5600, and SRX5800)—Starting in Junos OS Release 22.4R1, you can change the speed configuration of a 10-Gbps port to operate at 1-Gbps. You can make this change by configuring the speed value as 1-Gbps in the set interfaces <intf-name> gigether-options speed 1g command. sAfter you commit the configuration, the operating speed of the 10-Gbps port changes to 1 Gbps.
