3.
(Optional.) Specify the
source interface for IPv6
NetStream data packets
sent to the NetStream
servers.
ipv6 netstream export source
interface
interface-type
interface-number
By default, no source interface
is specified for IPv6 NetStream
data packets. The packets take
the IPv6 address of the output
interface as the source IPv6
address.
As a best practice, connect the
management Ethernet interface
to a NetStream server, and
configure the interface as the
source interface.
4.
(Optional.) Limit the
IPv6 NetStream data
export rate.
ipv6 netstream export rate
rate
By default, the data export rate
is not limited.
Configuring the IPv6 NetStream aggregation data export
The IPv6 NetStream aggregation can be implemented by software or hardware. Unless otherwise
noted, NetStream aggregation refers to software NetStream aggregation.
IPv6 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 IPv6 NetStream
hardware aggregation entries is the same as the aging of IPv6 NetStream traditional data entries.
When a hardware aggregation entry is aged out, the data is exported.
IPv6 NetStream hardware aggregation reduces resource consumption.
Configuration restrictions and guidelines
When you configure the IPv6 NetStream aggregation data export, follow these restrictions and
guidelines:
•
The IPv6 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 IPv6 NetStream hardware
aggregation.
•
Configurations in IPv6 NetStream aggregation mode view apply only to the IPv6 NetStream
aggregation data export. Configurations in system view apply to the IPv6 NetStream traditional
data export. When no configuration in IPv6 NetStream aggregation mode view is provided, the
configurations in system view apply to the IPv6 NetStream aggregation data export.
