deletes the analyzer.
62.3 sFlow Examples
Figure 62.1: sFlow configuration topology
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 as follows:
Switch#config
Switch(config)#sflow agent-address 10.1.144.2
Switch(config)#sflow destination 192.168.1.200
Switch(config)#sflow priority 1
Switch(config)#interface ethernet1/1
Switch(Config-If-Ethernet1/1)#sflow rate input 10000
Switch(Config-If-Ethernet1/1)#sflow rate output 10000
Switch(Config-If-Ethernet1/1)#sflow counter-interval 20
Switch(Config-If-Ethernet1/1)#exit
Switch(config)#interface ethernet1/2
Switch(Config-If-Ethernet1/2)#sflow rate input 20000
Switch(Config-If-Ethernet1/2)#sflow rate output 20000
Switch(Config-If-Ethernet1/2)#sflow counter-interval 40
