57.3 sFlow Examples

As shown in the figure, sFlow sampling is enabled on the port 1/1 and 1/2 of the switch. Assume the sFlow
analysis software is installed on the PC with the address of 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 a s follows:
XGS 3-42000R#config
XGS 3-42000R(config)#sflow ageng-address 10.1. 144. 2
XGS 3-42000R(config)#sflow destination 192.168.1.200
XGS 3-42000R(config)#sflow priority 1
XGS 3-42000R(config)# interfac e ethernet 1/1
XGS 3-42000R(Config-If-Ethernet1/1)#sflow rate input 10000
XGS 3-42000R(Config-If-Ethernet1/1)#sflow rate output 10000
XGS 3-42000R(Config-If-Ethernet1/1)#sflow counter-interval 20
XGS 3-42000R(Config-If-Ethernet1/1)#exit
XGS 3-42000R(config)# interfac e ethernet 1/2
XGS 3-42000R(Config-If-Ethernet1/2)#sflow rate input 20000
XGS 3-42000R(Config-If-Ethernet1/2)#sflow rate output 20000
XGS 3-42000R(Config-If-Ethernet1/2)#sflow counter-interval 40

57.4 sFlow Troubleshooting

In configuring and using sFlow, the sFlow server may fail t o run properly due to physical connection failure,
wrong configuration, etc. The user should ensure the following:
 Ensure the physical connection is correct

Guarant ee 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.
