Using the sampler for IPv4 NetStream
Network requirements
As shown in Figure 51 , configure IPv4 NetStream on the SecBlade to collect statistics on incoming traffic
on Ten-GigabitEthernet 0/0. The NetStream data is sent to port 5000 on the NSC at 12.110.2.2/24.
Configure fixed sampling in the inbound direction to select the first packet out of 256 packets.
