The following commands configure an NEC switch (, sampling packets at 1-in-2048, polling counters every 30 seconds and sending sFlow to an analyzer ( over UDP using the default sFlow port (6343):

sflow source
sflow destination 6343
sflow sample 2048
sflow polling-interval 30

For each interface:

A previous posting discussed the selection of sampling rates. Additional information can be found on the NEC web site.

See Trying out sFlow for suggestions on getting started with sFlow monitoring and reporting.
