Configuring NetStream aggregation data export
NetStream aggregation can be implemented by software or hardware. Generally, the term of NetStream
aggregation refers to the implementation by software, unless otherwise noted.
The NetStream hardware aggregation directly merges the statistics of data flows at the hardware layer
according to the aggregation criteria of a specific aggregation mode, and stores the NetStream
hardware aggregation data in the cache. When the timer for the hardware aggregation entry expires,
the data is exported. This greatly reduces the resource consumption by NetStream aggregation.
Without hardware aggregation configured, the NetStream data aggregation is implemented by
software.
To configure NetStream aggregation data export:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the
NetStream
hardware
aggregation.
ip netstream aggregation advanced
Optional.
By default, NetStream hardware
aggregation is disabled.
3. Set a NetStream
aggregation mode
and enter its view.
ip netstream aggregation { as |
destination-prefix | prefix | prefix-port
| protocol-port | source-prefix | tos-as |
tos-destination-prefix | tos-prefix |
tos-protocol-port | tos-source-prefix |
tos-bgp-nexthop }
N/A
4. Configure the
destination address
for the NetStream
aggregation data
export.
ip netstream export host ip-address
udp-port [ vpn-instance
vpn-instance-name ]
By default, no destination address is
configured in NetStream aggregation
view. Its default destination address is
that configured in system view.
If you expect to export only NetStream
aggregation data, configure the
destination address in related
aggregation view only.
5. Configure the
source interface for
NetStream
aggregation data
export.
ip netstream export source interface
interface-type interface-number
Optional.
By default, the interface connecting to
the NetStream server is used as the
source interface.
• Source interfaces in different
aggregation views can be different.
• If no source interface is configured
in aggregation view, the source
interface configured in system view
is used.
• H3C recommends that you connect
the network management interface
to the NetStream server.
6. Enable the current
NetStream
aggregation
configuration.
enable
By default, the current NetStream
aggregation configuration is disabled.
