192.168.1.200. The address of the layer 3 interface on the SwitchA connected with PC is

192.168.1.100. A loopback interface with the address of 10.1.144.2 is configured on the

SwitchA. sFlow configuration is as follows:

Configuration procedure is as follows:

Switch#config

Switch (config)#sflow ageng-address 10.1.144.2

Switch (config)#sflow destination 192.168.1.200

Switch (config)#sflow priority 1

Switch (config)# interface ethernet1/0/1

Switch (Config-If-Ethernet1/0/1)#sflow rate input 10000

Switch (Config-If-Ethernet1/0/1)#sflow rate output 10000

Switch (Config-If-Ethernet1/0/1)#sflow counter-interval 20

Switch (Config-If-Ethernet1/0/1)#exit

Switch (config)# interface ethernet1/0/2

Switch (Config-If-Ethernet1/0/2)#sflow rate input 20000

Switch (Config-If-Ethernet1/0/2)#sflow rate output 20000

Switch (Config-If-Ethernet1/0/2)#sflow counter-interval 40

sFlow Troubleshooting

In configuring and using sFlow, the sFlow server may fail to run properly due to

physical connection failure, wrong configuration, etc. The user should ensure the

following:

 Ensure the physical connection is correct

 Guarantee the address of the sFlow analyzer configured under global or port mode is

accessible.

 If traffic sampling is required, the sampling rate of the interface must be configured

 If statistic sampling is required, the statistic sampling interval of the interface must

be configured

If the examination remains unsolved, please contact with the technical service center

of our company.
