  • Enhanced CPU core allocation for Routing Engine (vSRX 3.0)—You can enhance system stability and performance in vSRX 3.0 by configuring even numbers of CPU cores for the Routing Engine. When you launch vSRX 3.0 instances with even numbers of CPU cores configured, by default two CPU cores are allocated to the Routing Engine. This allocation enhances system stability and ensures the efficient operation of both the Routing Engine and Packet Forwarding Engine. For systems with an odd number of CPU cores, only one core is allocated to the Routing Engine.

    The set security forward-options resource-manager cpu re <n> command is now deprecated. You cannot manually configure the number of CPU cores on the Routing Engine because the default assignment automatically allocates these cores.

    Use the show security forward-options resource-manager settings to verify the RE CPU core count.
