Distributed mode for fast BFD and Dedicated Offload CPU (vSRX 3.0)—Distributed mode for fast Bidirectional Forwarding Detection (BFD) offers a quicker failure detection time of 900 milliseconds. You can use this feature in both stand-alone and L3-HA mode. To activate distributed mode, set the BFD failure detection time to 500 milliseconds. Additionally, vSRX 3.0 includes a dedicated offload CPU feature. This feature reallocates a flow thread and employs the Data Plane Development Kit (DPDK) flow filters on the network interface card (NIC) to shift high-priority packets onto the dedicated flow thread.
To enable the dedicated offload CPU on vSRX 3.0, run the
set security forwarding-options dedicated-offload-cpu
command.To view the current dedicated offload CPU status use the
show security forward-options dedicated-offload-cpu
command.[See Understanding How BFD Detects Network Failures, Configuring BFD, and detection-time (BFD Liveness Detection).]
