sFlow Configuration Example
Network requirements
z
Host A and Server are connected to Switch through GigabitEthernet 1/0/1 and GigabitEthernet
1/0/2 respectively.
z
Host B works as an sFlow collector with IP address 3.3.3.2 and port number 6343, and is
connected to Switch through GigabitEthernet 1/0/3.
z
GigabitEthernet 1/0/3 belongs to VLAN 1, having an IP address of 3.3.3.1.
Run sFlow agent on Switch, and enable sFlow on GigabitEthernet 1/0/1 to monitor traffic on this
interface. Switch sends sFlow packets through GigabitEthernet 1/0/3 to Host B, which then analyzes
the sFlow packets and displays the results.
