3.11 Troubleshooting the sFlow statistics (flow statistics)
functionality
The following figure shows the workflow for troubleshooting the sFlow statistics
functionality on the Switch.
Figure 3-7 Workflow for troubleshooting the sFlow statistics functionality
3.11.1 sFlow packets cannot be sent to the collector
(1) Checking the route to the collector
See 3.6.1 Communication is not possible or is disconnected and 3.7.1 Communication is
not possible or a disconnection occurred , and make sure that the network is correctly
connected to the collector. If the maximum size of an sFlow packet
(
sflow-max-packet-size ) has been modified in the 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 operation command a few times to display the sFlow statistics,
and check whether the sFlow statistics functionality is running. If the underlined values do
not increase, see
(3) Checking the configuration . If the values increase, see 3.6.1
Communication is not possible or is disconnected and 3.7.1 Communication is not possible
or a disconnection occurred , and (5) Checking the settings on the collector , and make sure
the network is correctly connected to the collector.
