(Optional.) Configure periodical
aging.
•
Set the aging timer for active
flows:
ip netstream timeout active
minutes
•
Set the aging timer for
inactive flows:
ip netstream timeout
inactive seconds
By default:
•
The aging timer for active
flows is 5 minutes.
•
The aging timer for
inactive flows is 300
seconds.

1.
Enter system view.
system-view
N/A
2.
Specify a destination host
for NetStream traditional
data export.
ip netstream export host
ip-address udp-port
[
vpn-instance
vpn-instance-name
]
By default, no destination host is
specified. No NetStream traditional
data is exported.
3.
(Optional.) Specify the
source interface for
NetStream data packets
sent to NetStream
servers.
ip netstream export source
interface
interface-type
interface-number
By default, no source interface is
specified for NetStream data packets.
The packets take the IP address of the
output interface as the source IP
address.
4.
(Optional.) Limit the data
export rate.
ip netstream export rate rate
By default, the data export rate is not
limited.
Configuring the NetStream aggregation data export
NetStream aggregation can be implemented by software or hardware. Unless otherwise noted,
NetStream aggregation refers to software NetStream aggregation.
NetStream hardware aggregation uses hardware to directly merge the flow statistics according to the
aggregation mode criteria, and stores the data in the cache. The aging of NetStream hardware
aggregation entries is the same as the aging of NetStream traditional data entries. When a hardware
aggregation entry is aged out, the data is exported.
NetStream hardware aggregation reduces the resource consumption by NetStream aggregation.
Configuration restrictions and guidelines
When you configure the NetStream aggregation data export, follow these restrictions and guidelines:
•
The NetStream hardware aggregation does not take effect in the following situations:
The destination host is configured for NetStream traditional data export.
The configured aggregation mode is not supported by NetStream hardware aggregation.
•
Configurations in NetStream aggregation mode view apply only to the NetStream aggregation
data export, and those in system view apply to the NetStream traditional data export. If
