Step Command Remarks
3. (Optional.) Set the flow
sampling mode. sflow sampling-mode { determine
| random }
The default setting is random.
The determine keyword is not
supported in the current software
version. It 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, no flow sampling rate is
configured.
5. (Optional.) Set the maximum
number of bytes (starting from
the packet header) that flow
sampling can copy per
packet.
sflow flow max-header length
The default setting is 128 bytes.
H3C recommends the default.
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.
• Sends them in UDP packets to the specified sFlow collector.
To configure counter sampling:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Layer 2 Ethernet
interface view. interface interface-type
interface-number
N/A
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.
Displaying and maintaining sFlow
Execute display commands in any view.
Task Command
