cpu-class-show
Netvisor’s CPU Control Packet Processing Protection feature allows the CPU control packet processing path be protected against misbehaving and malicious hosts or end-points that may flood control protocol packets. This is also called “CPU hog protection”.
If a host floods a control protocol packet, it floods the to-cpu queue. This prevents lower-rate packets from valid senders from reaching Netvisor, resulting in traffic loss for those hosts. Typically a traffic loss occurs for other hosts on the network. Netvisor can process large streams of both valid and malformed protocol packets for various protocols.
