Configuring Versions for Exported Packets

Configuring Versions for Exported Packets

Context

The NDE exports NetStream flow statistics to the NSC. The version of exported packets must be the same as that configured on the NSC so that the NSC can parse the exported packets.

Exported packets in V8 have fixed format and are difficult to expand. The format of exported packets in V9 is defined in templates and is easy to expand. The statistics are exported flexibly.

Because of its advantages, V9 is supported by most NSCs. It is recommended that you set the version of exported packets carrying aggregation flow statistics to V9.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the netstream aggregation ip { as | as-tos | bgp-nexthop-tos | destination-prefix | destination-prefix-tos | index-tos | mpls-label | prefix | prefix-tos | protocol-port | protocol-port-tos | source-prefix | source-prefix-tos | source-index-tos | vlan-id } command to enter the NetStream aggregation view.

    The aggregation view must be the same as the aggregation view in Configuring NetStream Aggregation Flow Statistics Export.

    NOTE:

    Only the CE8868EI, CE8861EI, CE8860EI, CE8850EI, CE7855EI, CE7850EI, CE6875EI, CE6870EI, CE6865EI, CE6860EI, CE6857EI, CE6856HI, CE6855HI, CE6851HI, CE6850HI, and CE6850U-HI support the mpls-label parameter.

    The CE6880EI and CE5880EI do not support MPLS or sampling of AS and BGP next hop information, so the CE6880EI and CE5880EI do not support the mpls-label, as, as-tos, and bgp-nexthop-tos parameters.

  3. Run the export version { 8 | 9 } command to set the version of exported packets carrying aggregation flow statistics.

    For the aggregation modes as, as-tos, destination-prefix, destination-prefix-tos, prefix, prefix-tos, protocol-port, protocol-port-tos, source-prefix, and source-prefix-tos, the default version is V8. You can specify the version of exported packets.

    For the aggregation modes vlan-id, bgp-nexthop-tos, index-tos, mpls-label and source-index-tos the default version is fixed as V9, and these aggregation modes do not support the export version command.

  4. (Optional) Run the template timeout-rate timeout-interval command to set the interval at which the template for exporting aggregation flow statistics in V9 format is refreshed.

    By default, the template is refreshed every 1 minute.

    NOTE:

    If the default template update interval (30 minutes) is used in V200R001C00 or an earlier version, the interval is automatically changed to 1 minute after the version is upgraded to V200R002C50 or later.

    If the default template update interval (1 minute) is used in V200R002C50 or a later version, the interval is automatically changed to 30 minutes after the version is downgraded to V200R001C00 or an earlier version.

  5. Run the commit command to commit the configuration.
