3. (Optional.) Set the flow
sampling mode.
sflow sampling-mode { determine
| random }
By default, the device samples
packets in random mode.
The determine sampling mode is
not supported in the current
software version. The determine
keyword is reserved for future
support.
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 periodically
collects the counter information on that interface, encapsulates the information into sFlow packets, and
sends them in UDP packets to the specified sFlow collector.

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.
