How Do I Configure NetStream?

How Do I Configure NetStream?

CE switches provide the NetStream feature to collect statistics on original flows, aggregation flows, flexible flows, and Layer 2 flows. The following describes how to configure NetStream to collect statistics on IPv4 original flows. For details about how to configure NetStream to collect statistics on other types of flows, see the CE switch product documentation.

# Set the NetStream sampling rate. Set the sampling rate in both the inbound and outbound directions of 10GE1/0/1 to 8192.
<HUAWEI> system-view
[~HUAWEI] interface 10ge 1/0/1
[~HUAWEI-10GE1/0/1] netstream sampler random-packets 8192 inbound
[*HUAWEI-10GE1/0/1] netstream sampler random-packets 8192 outbound
[*HUAWEI-10GE1/0/1] quit
# Set the NetStream flow aging mode and aging time. Set the inactive aging time to 100 seconds and enable FIN- and RST-based aging.
[*HUAWEI] netstream timeout ip inactive 100
[*HUAWEI] netstream timeout ip tcp-session
# Set the source IP address, destination IP address, and destination port number of the exported packets carrying original flow statistics.
[*HUAWEI] netstream export ip source 10.1.2.1
[*HUAWEI] netstream export ip host 10.1.2.2 6000
# Set the version of exported NetStream packets.
[*HUAWEI] netstream export ip version 9
# Enable NetStream statistics collection on 10GE1/0/1 for incoming and outgoing packets.
