Configuring NetStream Flexible Flow Statistics Export

Configuring NetStream Flexible Flow Statistics Export

Context

Flexible flow statistics can be exported only when a source IP address and at least one destination IP address and one destination UDP port number have been specified for the exported packets.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the netstream export ipv6 source { ip-address | ipv6 ipv6-address } command to configure the source IP address for the exported packets carrying IPv6 flexible flow statistics.

    By default, the source IP address of the exported packets carrying IPv6 flexible flow statistics is not configured.

    If the source IP address has not been specified, packets will not be exported. The source address of the exported packets carrying IPv6 flexible flow statistics can be an IPv4 or IPv6 address. There must be a reachable route between the source IP address and destination IP address (NSC address). Two source IP addresses can be specified: one IPv4 address and one IPv6 address.

  3. Run the netstream export ipv6 host { ip-address | ipv6 ipv6-address } port-number [ vpn-instance vpn-instance-name ] command to configure the destination IP address and destination UDP port number for the exported packets carrying IPv6 flexible flow statistics.

    By default, the destination IP address and destination UDP port number of the exported packets carrying IPv6 flexible flow statistics are not configured.

    You can configure two destination IP addresses to implement NSC backup. To configure a third destination IP address, first run the undo netstream export ipv6 host command to delete an existing one first. Otherwise, the system will display a message indicating that the maximum number of IP addresses has been reached and the configuration will fail.

  4. (Optional) Run the assign netstream management-plane export rate-limit rate-limit [ slot slot-id ] command to limit the rate of NetStream packets sent from a switch to the control plane, thereby limiting the rate of NetStream packets sent out by the control plane.

    By default, the rate of NetStream packets sent to the control plane is not limited.

    A switch sends NetStream packets to the control plane only when the switch selects the management interface to send NetStream packets to the NetStream server. If the assign netstream management-plane export rate-limit rate-limit slot slot-id command has been executed to limit the rate of NetStream packets sent from a specified card to the control plane, you cannot run the assign netstream management-plane export rate-limit rate-limit command to limit the rate of NetStream packets sent from all cards to the control plane. If the assign netstream management-plane export rate-limit rate-limit command has been executed to limit the rate of NetStream packets sent from all cards to the control plane, you cannot run the assign netstream management-plane export rate-limit rate-limit slot slot-id command to limit the rate of NetStream packets sent from a specified card to the control plane.

    NOTE:

    The CE6880EI and CE5880EI do not support this command because they can only use service interfaces to export NetStream packets.

  5. (Optional) Run the netstream export packet-len ethernet-crc command to configure the IN_BYTES field value in NetStream packets to include the Ethernet header and CRC lengths.

    By default, the IN_BYTES field value in NetStream packets is the len field value in the IP packet header.

  6. Run the commit command to commit the configuration.
