Configuring Flow Exports on Huawei Devices

For NetFlow analysis, you need to configure your devices to export flows to Site24x7 On-Premise Poller, which is the NetFlow collector. The On-Premise Poller will be listening to the particular port to receive flows. Learn how to find the port number of your On-Premise Poller.

sFlow configuration

Configure sFlow on Huawei devices using the following commands:

1. Configuring the sFlow agent IP
   The sFlow agent IP is the device’s IP address used for exporting flow data to the collector.

   sflow
   sflow agent ip  
   commit

2. Configuring the sFlow collector
   Set the IP address of the sFlow collector (Site24x7 On-Premise Poller) and commit the changes.

   sflow collector 1
   commit
   sflow server ip 
   commit
   quit
   quit

3. Enabling sFlow on a specified slot
   Activate sFlow on the relevant slot where traffic flows will be monitored.
   

   slot 4
   sflow enable
   commit
   quit

4. Configuring flow sampling
   Define how often sFlow samples packets on a specific interface.
   

   interface GigabitEthernet 0/1/3
   sflow flow-sampling collector 1 inbound
   commit
   sflow flow-sampling rate 2000 inbound
   commit
   quit

5. Verifying the sFlow configuration
   Run the following command to verify if the sFlow configuration is correct.
   

   display sflow configuration

NetStream configuration

1. Configuring the NTP server
   Ensure time synchronization across devices by configuring the NTP server.
   

   ntp-service server disable 
   ntp-service ipv6 server disable 
   ntp-service unicast-peer 
   ntp-service unicast-peer 

   This exports the NetStream exports to the specified IP address. Specify the IP address of the machine on which Site24x7 On-Premise Poller is installed and the configured listener port. The default port is 9996.
   
2. Configuring the slot to export flow information
   Specify the slot from which flow data will be exported. Replace "3" with the actual slot number if different.
   

   slot 3 (Replace "3" with your actual slot number if different.)
   ip netstream sampler to slot self  
   ipv6 netstream sampler to slot self

3. Configuring NetStream export settings
   Set the NetStream export settings, including version, source IP, and host IP.
   

   ip netstream timeout active 1
   ip netstream timeout inactive 15
   ip netstream export version 9
   ip netstream export index-switch 32
   ip netstream export template timeout-rate 1
   ip netstream sampler fix-packets 500 inbound
   ip netstream sampler fix-packets 500 outbound
   ip netstream export source 
   ip netstream export host  2055
   ip netstream export template option sampler
   ip netstream export template option timeout-rate 1
   ip netstream as-mode 32
   ipv6 netstream as-mode 32
   ipv6 netstream timeout active 1
   ipv6 netstream timeout inactive 15
   ipv6 netstream export version 9
   ipv6 netstream export index-switch 32
   ipv6 netstream export template timeout-rate 1
   ipv6 netstream sampler fix-packets 500 inbound
   ipv6 netstream sampler fix-packets 500 outbound
   ipv6 netstream export source 
   ipv6 netstream export host  2055
   ipv6 netstream export template option sampler
   ipv6 netstream export template option timeout-rate 1
   ipv6 netstream as-mode 32

4. Enabling NetFlow on interfaces
   Enable NetFlow on the interfaces that will export flow data.
   

   ip netstream inbound  
   ipv6 netstream inbound
