Configuring NetStream RPF Check Failure Flow Statistics Exporting

Configuring NetStream RPF Check Failure Flow Statistics Exporting


Statistics about flows that fail the RPF check can be exported only when you have specified at least one destination IP address and one destination UDP port number for the exported packets.


  1. Run system-view

    The system view is displayed.

  2. (Optional) Run ip netstream as extend enable

    The supported BGP AS number range is set.

    By default, the BGP AS numbers range from 1 to 65535.

    Only the output packets of V9 or V10 support the 32-bit BGP AS numbers. The ip netstream as extend enable command needs to be executed to set the supported BGP AS number range to 1-4294967295.

  3. Run ip netstream export source ip-address

    The source address of the exported packets carrying flow statistics is configured.

  4. Run ip netstream export host ip-address port-number

    The destination IP address and destination UDP port number are configured for the flow statistics packets exported to the NSC.

    You can configure two destination IP addresses to implement NSC backup. To configure a third destination IP address, run the undo ip netstream export host command to delete an existing one first; otherwise, the system displays a message indicating that the maximum number of IP addresses is exceeded and the configuration fails.
