6.4.2 Configuring an Aggregation Mode for IPv4 Flows

After an aggregation mode is configured, original flows with the same characteristics are
aggregated as one flow and output to the NSC to meet users' requirements.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ip netstream aggregation { as | as-tos | bgp-nexthop-tos | destination-prefix |
destination-prefix-tos | index-tos | prefix | prefix-tos | protocol-port | protocol-
port-tos | source-prefix | source-prefix-tos }
The NetStream aggregation view is created.

NOTE
If the NetStream flow aggregation function is enabled on a device, the device classifies and aggregates
original flows based on certain rules and sends the aggregated flows to the NDA for analysis. Aggregating
original flows can reduce the consumption of network bandwidths, CPU resources, and storage space. Flow
characteristics based on which flows are aggregated vary according to flow aggregation modes. For
mapping relationships between aggregation modes and flow characteristics, see the following table.

Description
NetStream flows with the same source AS number, destination
AS number, inbound interface index, and outbound interface
index are aggregated as one flow, and one aggregation record
is generated.
NetStream flows with the same source AS number, destination
AS number, inbound interface index, outbound interface
index, and ToS are aggregated as one flow and one aggregation
record is generated.
NetStream flows with the same destination AS number, source
AS number, BGP next hop, inbound interface index, and
outbound interface index are aggregated as one flow and one
aggregation record is generated.
NetStream flows with the same destination AS number,
destination mask length, destination prefix, and outbound
interface index are aggregated as one flow and one aggregation
record is generated.
