3. (Optional.) Set the flow
sampling mode.
sflow sampling-mode { determine
| random }
The default setting is random.
The switch does not support the
determine mode.
4. Enable flow sampling and
specify the number of packets
out of which flow sampling
samples a packet on the
interface.
sflow sampling-rate rate
By default, flow sampling samples
no packet.
5. (Optional.) Set the maximum
number of bytes of a packet
(starting from the packet
header) that flow sampling
can copy.
sflow flow max-header length The default setting is 128 bytes.
6. Specify the sFlow collector for
flow sampling.
sflow flow collector collector-id
By default, no sFlow collector is
specified for flow sampling.
Configuring counter sampling
Perform this task to configure counter sampling on an Ethernet interface. The sFlow agent does the
following:
• Periodically collects the counter information on that interface.
• Encapsulates the information into sFlow packets.
• Encapsulates the sFlow packets in UDP packets and sends the UDP packets to the specified sFlow
collector.
To configure counter sampling:

3. Enable counter sampling and
set the counter sampling
interval.
sflow counter interval interval-time
By default, counter sampling is
disabled.
4. Specify the sFlow collector for
counter sampling.
sflow counter collector collector-id
By default, no sFlow collector is
specified for counter sampling.
