sflow sampling-rate rate
Optional
200000 by default, that is, one out
of every 200000 packets is
sampled.
z The sFlow agent and sFlow collector must not have the same IP address.
z Currently, you can specify at most two sFlow collectors on the device.
z The sFlow agent and sFlow collector must be configured with the same version of IP addresses.

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