(3) Checking configuration

Check the configuration in operation on the following points:

•Check that the IP address and UDP port number of the sFlow packet destination collector are set correctly in configuration.

Figure 3-20: Display Example Configuration 1

 

(config)# show sflow

<- Collector information must be set correctly.

sflow destination 192.1.1.1 6455

sflow sample 2048

 

!

 

(config)#

 

•Check that the sampling interval is set.

If the sampling interval is not set, the system operates with default value (large value), which is so large that flow sample is seldom sent to the collector. Set the appropriate sampling interval. However, if the value extremely smaller than the recommended value is set, the CPU usage may be raised.

(config)# show sflow
