Configuring sampler examples
Network requirements
As shown in Figure 63, configure IPv4 NetStream on Switch A to collect statistics on coming traffic on
GigabitEthernet 1/0/1 and send the result to port 5000 on NSC 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 out of 256
(two to the power of eight) packets is selected.

[SwitchA] sampler 256 mode fixed packet-interval 8
# Configure interface GigabitEthernet 1/0/1, enable IPv4 NetStream to collect statistics on the incoming
traffic, and configure the interface to use sampler 256.
[SwitchA] interface GigabitEthernet1/0/1
[SwitchA-GigabitEthernet1/0/1] ip netstream inbound
[SwitchA-GigabitEthernet1/0/1] ip netstream sampler 256 inbound
[SwitchA-GigabitEthernet1/0/1] quit
# Configure the IP address and port number of the NSC as the destination address and port number for
NetStream data export, leaving the default for source interface.
[SwitchA] ip netstream export host 12.110.2.2 5000
