Denial of service (DDoS) protection protocol prioritization

The type of line card in the device drives the distributed denial of service (DDoS) priority of incoming protocols. Starting in Junos OS Release 23.2R1, the device determines the DDoS priority of a protocol based on the DDoS parameters table. This enhancement enables the device to treat all packets of a particular protocol the same by default, regardless of the device's line card. You can modify the DDoS parameters table using CLI. This feature improves consistency in the way devices in the network prioritize protocols to protect against DDoS attacks.
