Configuring Counter Sampling; Displaying And Maintaining Sflow - HPE FlexNetwork 5510 HI Series Network Management And Monitoring Configuration Manual

Step
4. Enable flow sampling and
specify
packets out of which flow
sampling samples a packet
on the interface.
5. (Optional.) Set the maximum
number of bytes (starting
from the packet header) that
flow sampling can copy per
packet.
6. Specify the sFlow collector
for flow sampling.

Configuring counter sampling

Perform this task to configure counter sampling on an Ethernet interface. The sFlow agent performs
the following operations:
1. Periodically collects the counter information on that interface.
2. Encapsulates the counter information into sFlow packets.
3. Encapsulates the sFlow packets in the UDP packets and sends the UDP packets to the
specified sFlow collector.
To configure counter sampling:
Step
1. Enter system view.
2. Enter
interface view or Layer 3
Ethernet interface view.
3. Enable
and set the counter sampling
interval.
4. Specify the sFlow collector
for counter sampling.
