Using the sampler for NetStream
NOTE:
This feature is supported by SPC cards only.
Network requirements
As shown in Figure 44 , configure IPv4 NetStream on Router A to collect statistics on incoming traffic on
GigabitEthernet 3/1/0. The NetStream data is sent to port 5000 on the NSC at 12.110.2.2/16.
Configure fixed sampling in the inbound direction to select the first packet out of 256 packets.

Configuration procedure
# Create sampler 256 in fixed sampling mode and set the sampling rate to 8. The first packet of 256 (2
to the power of 8) packets is selected.
