Configuring sFlow globally

Execute the following steps to configure sFlow globally.

1. Enter the configure terminal command to change to global configuration mode.
   

   device# configure terminal

2. Enable the sFlow protocol globally.
   

   device (config)# sflow enable

3. Configure sFlow collectors and optionally associated UDP ports.
   

   device(config)# sflow collector 172.22.12.83 6343 use-vrf mgmt-vrf
   device(config)# sflow collector fdd1:a123:b123:c123:34:1:1:2 4713 use-vrf vrf2
   device(config)# sflow collector fdd1:a123:b123:c123:112:1:1:2 5566 use-vrf default-vrf

4. Set the sFlow polling interval (in seconds).
   

   device(config)# sflow polling-interval 35

5. Set the sFlow sample-rate.
   

   device(config)# sflow sample-rate 4096

6. Return to privileged EXEC mode.
   

   device(config)# end

7. Confirm the sFlow configuration status by using the show sflow or show sflow all commands.
   

   device# show sflow

8. Clear any existing sFlow statistics to ensure accurate readings.
   

   device# clear sflow statistics

   

   Note

   No specific configuration is required for MPLS other than enabling sflow on physical interfaces.
