6.5.1 Specifying a NetStream Service Processing Mode

After performing packet sampling, each NetStream-enabled LPU sends sampled packets to the
NetStream service processing board for aggregation and output. If the NE5000E has more than
one NetStream service processing board, these NetStream services boards work in redundancy
mode for service backup and load balancing, which improves system reliability.
Context
NetStream services can be processed in either of the following modes:
l
l
The ip netstream sampler command has the same function as the ipv6 netstream sampler
command.

Mandatory procedure
Optional procedure
Distributed mode
In this mode, a single LPU can perform NetStream functions independently, including
packet sampling, flow aggregation, and flow output.
Integrated mode
In this mode, the LPU only samples packets and sends sampled packets to the NetStream
service processing board. Flow aggregation and flow output are performed on the
NetStream service processing board. If the data volume collected by the router is beyond
the processing capability of a single NetStream service processing board, additional
NetStream service processing boards for load balancing can be installed.
The execution of either command takes effect on all packets and there is no need to
configure both of them. If it is required to configure both of them, ensure that sampling
modes and sampling ratios configured by the ip netstream sampler and ipv6 netstream
sampler commands are identical.
