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.
    switch# config
    switch(config)# sflow
  2. Set the sFlow agent IP address to 10.10.12.1.
    switch(config)# sflow agent-ip 10.10.12.1
  3. Set the sFlow collector IP address to 10.10.12.2.
    switch(config)# sflow collector 18.2.2.2
  4. Configure sFLow sampling rate and polling interval.
    switch(config)# sflow sampling 5000
    switch(config)# sflow polling 20
  5. Configure interface 1/1/1 with IP address 10.10.10.1/24.
    switch(config)# interface 1/1/1
    switch(config-if)# no shutdown
    switch(config-if)# ip address 10.10.10.1/24
    switch(config)# quit
  6. Configure interface 1/1/2 with IP address 10.10.11.1/24.
    switch(config)# interface 1/1/1
    switch(config-if)# no shutdown
    switch(config-if)# ip address 10.10.11.1/24
    switch(config)# quit
  7. Configure interface 1/1/3 with IP address 10.10.12.1/24.
    switch(config)# interface 1/1/3
    switch(config-if)# no shutdown
    switch(config-if)# ip address 10.10.12.1/24
    switch(config)# quit
  8. Verify sFlow configuration.
    switch# show sflow
