Why does the NMS display incorrect NetStream data or no NetStream data after NetStream is enabled on an S series switch


1. The NMS has not imported the NetStream MIB, which is a Huawei Proprietary MIB.
2. The NetStream packet version configured on the switch is different from that configured on the NMS. Run the display netstream command on the switch to check the NetStream configuration.
3. The interface index configured on the switch does not match the NetStream packet version. V5 and V8 do not support 32-bit interface indexes. If a 32-bit interface index is configured, the NetStream packet version must be set to V9.

Configure NetStream on S series switches
NetStream is a traffic statistics and analysis technology. NetStream supports exporting of original, aggregation, and flexible flow statistics. The following is an example of configuring exporting of original flow on an S series switch (except the S1700). 1. Configure NetStream sampling on GE1/0/1, set the sampling mode to packet-based regular sampling, and set the interval to 1200. [HUAWEI] interface gigabitethernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] ip netstream sampler fix-packets 1200 inbound [HUAWEI-GigabitEthernet1/0/1] ip netstream sampler fix-packets 1200 outbound [HUAWEI-GigabitEthernet1/0/1] quit 2. Set the inactive aging time to 100 seconds and enable FIN- and RST-based aging. [HUAWEI] ip netstream timeout inactive 100 [HUAWEI] ip netstream tcp-flag enable 3. Set the source IP address of the exported packets carrying original flow statistics to, destination IP address to, and destination port number to 6000. [HUAWEI] ip netstream export source [HUAWEI] ip netstream export host 6000 4. Set the version of exported packets to version 9. [HUAWEI] ip netstream export version 9 5. Enable NetStream flow statistics collection on GE1/0/1. [HUAWEI] interface gigabitethernet 1/0/1 [HUAWEI-GigabitEthernet1/0/1] ip netstream inbound [HUAWEI-GigabitEthernet1/0/1] ip netstream outbound [HUAWEI-GigabitEthernet1/0/1] quit [HUAWEI] quit
