The source IP address configured in the aggregation view takes precedence over that configured
in the system view. If no source IP address is configured in the aggregation view, the source IP
address configured in the system view takes effect.
Step 7 Run:
ip netstream export host ip-address port
The destination IP address is configured for aggregated flows.
Step 8 (Optional) Configure parameters for aging aggregated flows as needed.

NOTE
l You can configure two destination IP addresses in the system view and the IPv4 NetStream aggregation
view.
l The destination IP address configured in the system view takes precedence over that configured in the
NetStream aggregation view.
ip netstream aggregation timeout active active-interval
The active aging time is configured for NetStream aggregated flows.
The default active aging time of NetStream aggregated flows is 5 minutes.
ip netstream aggregation timeout inactive inactive-interval
The inactive aging time is configured for NetStream aggregated flows.
The default inactive aging time of NetStream aggregated flows is 300 seconds.
AS field mode: As defined in the pertaining protocol, the length of the AS field in IP packets
is 16 bits. On networks in some areas, however, the length of the AS field in IP packets is
32 bits. If different AS field modes exist on a network, you need to convert the AS field
mode when configuring NetStream. Otherwise, NetStream cannot sample inter-AS traffic.
