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
