Configuração de Export Flow Huawei

ip netstream as-mode 32
ip netstream timeout active 1
ip netstream timeout inactive 15
ip netstream tcp-flag enable
ip netstream export version ipfix peer-as bgp-nexthop ttl
ip netstream export template sequence-number fixed
ip netstream export index-switch 32
ip netstream export template timeout-rate 1
ip netstream sampler fix-packets 1000 inbound
ip netstream sampler fix-packets 1000 outbound
ip netstream export source X.X.X.X
ip netstream export host X.X.X.X 2055
ip netstream export template option sampler
ip netstream export template option application-label

ipv6 netstream as-mode 32
ipv6 netstream timeout active 1

ipv6 netstream tcp-flag enable
ipv6 netstream export version ipfix peer-as bgp-nexthop ttl
ipv6 netstream export template sequence-number fixed

É Necessário capturar netstrem apenas as interfaces WAN

interface Eth-Trunk1.10
    ip netstream inbound
    ip netstream outbound
    ipv6 netstream inbound
    ipv6 netstream outbound

Caso utilize VS lembre de ativar o netstream na caixa principal

slot 10
 ip netstream sampler to slot self
 ipv6 netstream sampler to slot self
#

Caso você prefira e tiver capacidade de hardware no seu servidor para utilizar port mirror, segue a baixo.

interface de destino(interface wanguard)

interface GigabitEthernet1/0/0
port-observing observe-index 1

slot 9
mirror to observe-index 1 

#porta de origem ( links)

interface GigabitEthernet2/0/0
port-mirroring inbound
port-mirroring outbound

No caso de utilizar Flow, com essas configurações o seu servidor de wanguard já deve estar recebendo o fluxo de pacotes, vamos observar através do TCPDUMP.

tcpdump -i ens18 port 2055
