Configuring a NetStream Top Talkers Template

Configuring a NetStream Top Talkers Template

Context

When configuring the NetStream Top Talkers function, you need to configure a NetStream Top Talkers template first, and then apply the template to an interface. You can define the keywords used to filter traffic and traffic sorting order in the template.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the netstream top-talkers talker-name ip command to create a NetStream Top Talkers template and enter the template view.

    By default, no NetStream Top Talkers template exists.

  3. (Optional) Run the match ip { source-address ip-address [ mask ] | destination-address ip-address [ mask ] | nexthop-address ip-address [ mask ] | source-port { min port-number | max port-number } | destination-port { min port-number | max port-number } | source-as as-number [ origin | peer ] | destination-as as-number [ origin | peer ] | tos tos-value | dscp dscp-value | precedence precedence-value | protocol { protocol-number | tcp | udp } | packet-range { min minimum-range | max maximum-range } | byte-range { min minimum-range | max maximum-range } } command to specify the keywords used to filter traffic.

    By default, no keyword is specified in a NetStream Top Talkers template. If you run the command multiple times, multiple keywords are configured to filter traffic. The keywords tos, dscp, and precedence cannot be configured together in a NetStream Top Talkers template; otherwise, the filtering results may be unexpected. For example, if tos is specified, and then specify dscp, the device filters traffic based on the DSCP field of packets.

  4. Run the cache-timeout millisecond command to set the traffic statistics collection period in the NetStream Top Talkers template.

    By default, the traffic statistics collection period in a NetStream Top Talkers template is not set. You are advised to set the period longer than 600000 ms (10 minutes). If the period is too short, the collected traffic statistics may be incomplete.

  5. Run the top number number command to set the number of Top Talkers that can be recorded in the NetStream Top Talkers template.

    By default, the number of Top Talkers that can be recorded in a NetStream Top Talkers template is not set. A NetStream Top Talkers template can record a maximum of 200 Top Talkers.

  6. Run the sort-by { bytes | packets } command to specify the Top Talkers sorting order in the NetStream Top Talkers template.

    By default, the Top Talkers sorting order is not specified in a NetStream Top Talkers template. Top Talkers can be sorted in either of the following orders in a NetStream Top Talkers template:
    • Descending order of bytes: The Top Talker with the most bytes is listed on the top line.
    • Descending order of packets: The Top Talker with the most packets is listed on the top line.

  7. Run the commit command to commit the configuration.
