Netflow Analyser shows double speed on a vlan interface monitored on a huawei Router

Netflow Analyser shows double speed on a vlan interface monitored on a huawei Router

Hi, 

i have configured netstream on a huawei router with the following config:

ip netstream export version 9
ip netstream export index-switch 32
ip netstream timeout active 1
ip netstream timeout inactive 15
ip netstream export template timeout-rate 1
ip netstream export template option sampler
ip netstream export template option timeout-rate 1
ip netstream sampler fix-packets 500 inbound
ip netstream sampler fix-packets 500 outbound
ip netstream export source 192.168.1.1
ip netstream export host 192.168.1.100  1234

And also i have activated in a specific vlan i want to monitor the following two commands:

interface Vlanif10
 ip netstream inbound
 ip netstream outbound

However the Manageengine Netflow anlyser shows me the speed multiplied by two !  

That is the traffic is inbound at 60 Mbps and the Analyser displays 120 Mbps .

The same is true for the outbound traffic , it shows double than it is in reality.

Any ideas?

Thanks,
