3.16 Troubleshooting the sFlow statistics (flow statistics) functionality

The following figure shows the workflow for troubleshooting the sFlow statistics functionality on
the Switch.
Figure 3-19: Workflow for troubleshooting the sFlow statistics functionality

3.16.1 sFlow packets cannot be sent to the collector

(1) Checking the route to the collector
See 3.7.1 Communication is not possible or is disconnected and 3.10.1 Communication is not
possible or is disconnected, and make sure that the network is correctly connected to the collector.
If the maximum size of an sFlow packet (
configuration, check whether it is possible to connect to the collector with the specified packet size.
(2) Using an operation command to check the operation
Execute the
show sflow
the sFlow statistics functionality is running. If the underlined values do not increase, see
(3) Checking the configuration. If the values increase, see 3.7.1 Communication is not possible
or is disconnected, 3.10.1 Communication is not possible or is disconnected and (5) Checking the
settings on the collector, and make sure the network is correctly connected to the collector.
