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
- Show sFlow analyzer server settings: show sflow analyzer_server
- Show counter poller settings: show sflow counter_poller
- Show flow sampler settings: show sflow flow_sampler
- Show overall sFlow settings: show sflow
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
- 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.
