sFlow Configuration on D-Link Switches

Overview

sFlow is a feature on D-Link switches that allows for monitoring network traffic by sampling packets and sending them to an sFlow analyzer for analysis. This document provides a brief guide on configuring sFlow on D-Link switches using the Command Line Interface (CLI). Make sure that the port numbers match the expected configuration where UDP port number is 6343 (default for sflow)

Configuring sFlow

Enable sFlow: enable sflow

Create an sFlow analyzer server: create sflow analyzer_server <value 1-4> owner <name 16> {timeout <sec 1-2000000> | collectoraddress <ipaddr> | collectorPort <udp_port_number 1-65535> | maxdatagramsize <value 300-1400>}

Configure the sFlow analyzer server: config sflow analyzer_server <value 1-4> {timeout <sec 1-2000000> | collectoraddress <ipaddr> | collectorPort <udp_port_number 1-65535> | maxdatagramsize <value 300-1400>}

Create a counter poller: create sflow counter_poller ports [<portlist> | all] analyzer_server_id <value 1-4> {interval [disable | <sec 20-120>]}

Create a flow sampler: create sflow flow_sampler ports [<portlist> | all] analyzer_server_id <value 1-4> {rate <value 0-65535> | maxheadersize <value 18-256>}

Displaying sFlow Settings

Example Configuration 

DGS-3600:4# enable sflow
DGS-3600:4# create sflow analyzer_server 1 owner monitor collectoraddress 10.90.90.9
DGS-3600:4# create sflow counter_poller ports 1:1 analyzer_server_id 1 interval 20
DGS-3600:4# create sflow flow_sampler ports 1:1 analyzer_server_id 1 rate 10000 maxheadersize 128
Tips and Reminders
  • Make sure to configure the sFlow analyzer server with a valid IP address and UDP port number.
  • Configure the counter poller and flow sampler settings according to your network monitoring needs.
  • Use the show commands to verify your sFlow settings.
