show ddos-protection protocols violations

Control plane DDoS protection policers act on the system’s traffic queues. The QFX5100 and QFX5200 lines of switches manage traffic for more protocols than the number of queues, so the system often must map more than one protocol to the same queue. When traffic for one protocol shares a queue with other protocols and violates DDoS protection policer limits, this command reports a violation on that queue for all mapped protocols because the system doesn’t distinguish which protocol’s traffic specifically caused the violation. You can use what you know about the types of traffic flowing through your network to identify which of the reported protocols actually triggered the violation.
