2.8.4 sFlow Examples
Fig 2-5 sFlow configuration topology
As shown in the figure, sFlow sampling is enabled on the port 3/1 and 3/2 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 as follows:
Switch#config
Switch (config)#sflow ageng-address 10.1.144.2
Switch (config)#sflow destionation 192.168.1.200
Switch (config)#sflow priority 1
Switch (config)# (config)#in e3/1
Switch (Config-If-Ethernet3/1)#sflow rate input 10000
Switch (Config-If-Ethernet3/1)#sflow rate output 10000
Switch (Config-If-Ethernet3/1)#sflow rate counter-interval 20
Switch (Config-If-Ethernet3/1)#exit
Switch (config)# (config)#in e3/2
Switch (Config-If-Ethernet3/2)#sflow rate input 2000
Switch (Config-If-Ethernet3/2)#sflow rate output 20000
Switch (Config-If-Ethernet3/2)#sflow rate counter-interval 40
2.8.5 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
