Denial of service (DDoS) protocol classification for ARP request and reply traffic

You can configure separate DDoS protocol packet-types, bcast and ucast, at the [edit system ddos-protection protocols arp] hierarchy level for ARP request and reply traffic. The separate DDoS policers provide an improved packet rate limiting and priority handling for the ARP traffic. Prior to this release, the ARP request and reply traffic had a single DDoS protocol.
