This guide describes required configuration steps for Huawei routers (tested with NE40)
In this guide we use sampling rate 1:1000 and it works fine for bandwidth starting from 1G.
To enable Netstream for IPv4 protocol you need to apply following global configuration options:
ip netstream timeout active interval-second 15 ip netstream timeout inactive 15 ip netstream export version 9 ip netstream as-mode 32 ip netstream export template timeout-rate 1 ip netstream export template option timeout-rate 1 ip netstream export source YOUR_ROUTER_IP ip netstream export host FASTNETMON_IP 2055 ip netstream export template option sampler ip netstream inbound ip netstream outbound ip netstream sampler fix-packets 1000 inbound ip netstream sampler fix-packets 1000 outbound
To enable Netstream for IPv6 protocol you need to apply same commands but instead of using “ip netstream” please use “ipv6 netstream”.
To apply following commands you will need to know number of slot for line card. You can list all available line cards and get their slot IDs this way:
display device
Example output:
display device
S6730-H24X6C's Device status:
Slot Sub Type Online Power Register Status Role
--------------------------------------------------------------------------------------
0 - S6730-H24X6C Present PowerOn Registered Normal Master
PWR1 POWER Present PowerOn Registered Normal NA
PWR2 POWER Present PowerOn Registered Normal NA
FAN1 FAN Present PowerOn Registered Normal NA
FAN2 FAN Present PowerOn Registered Normal NA
FAN3 FAN Present PowerOn Registered Normal NA
FAN4 FAN Present PowerOn Registered Normal NA
Enable Netstream IPv4 for each available slot:
slot <slot id> ip netstream sampler to slot self
To enable Netsteram for IPv6 apply following command:
ipv6 netstream sampler to slot self
Or you may enable Netstream on interface basis for inbound:
interface <interface name> ip netstream inbound
And outbound:
interface <interface name> ip netstream outbound
To enable Netstream for IPv6 protocol in both directions on specific interface apply following commands:
interface <interface name> ipv6 netstream outbound ipv6 netstream inbound
Check Netstream export statistics:
display ip netstream statistics slot <slot id>
Example output:
===== Netstream statistics: ===== Origin/Flexible ingress entries : 12345 Origin/Flexible ingress packets : 12345 Origin/Flexible ingress octets : 12345 Origin/Flexible egress entries : 12345 Origin/Flexible egress packets : 12345 Origin/Flexible egress octets : 12345 Origin/Flexible total entries : 100 Handle origin entries : 800000 Handle As aggre entries : 0 Handle ProtPort aggre entries : 0 Handle SrcPrefix aggre entries : 0 Handle DstPrefix aggre entries : 0 Handle Prefix aggre entries : 0 Handle AsTos aggre entries : 0 Handle ProtPortTos aggre entries : 0 Handle SrcPreTos aggre entries : 0 Handle DstPreTos aggre entries : 0 Handle PreTos aggre entries : 0
On FastNetMon’s side you may specify sampling rate if needed using this guide:
sudo fcli set main netflow_sampling_ratio 1000 sudo fcli set main netflow_custom_sampling_ratio_enable enable sudo fcli commit
And specify average calculation time value:
sudo fcli set main average_calculation_time 30 sudo fcli commit
