sFlow scenario

In this scenario, two hosts send sFlow traffic through a switch to an sFlow collector. The physical topology of the network looks like this:

Procedure

  1. Enable sFlow globally.
  2. switch# config switch(config)# sflow

  3. Set the sFlow agent IP address to 10.10.12.1.
  4. switch(config)# sflow agent-ip 10.10.12.1

  5. Set the sFlow collector IP address to 10.10.12.2.
  6. switch(config)# sflow collector 18.2.2.2

  7. Configure sFLow sampling rate and polling interval.
  8. switch(config)# sflow sampling 5000 switch(config)# sflow polling 20

  9. Configure interface 1/1/1 with IP address 10.10.10.1/24.
  10. switch(config)# interface 1/1/1 switch(config-if)# no shutdown switch(config-if)# ip address 10.10.10.1/24 switch(config)# quit

  11. Configure interface 1/1/2 with IP address 10.10.11.1/24.
  12. switch(config)# interface 1/1/2 switch(config-if)# no shutdown switch(config-if)# ip address 10.10.11.1/24 switch(config)# quit

  13. Configure interface 1/1/3 with IP address 10.10.12.1/24.
  14. switch(config)# interface 1/1/3 switch(config-if)# no shutdown switch(config-if)# ip address 10.10.12.1/24 switch(config)# quit

  15. Verify sFlow configuration

switch# show sflow
