Configuring Flow Exports on D-Link Devices

For NetFlow analysis, you need to configure your devices to export flows to Site24x7 On-Premise Poller, which is the NetFlow collector. The On-Premise Poller will be listening to the particular port to receive flows. Learn how to find the port number of your On-Premise Poller.

Configure flows (sFlow) on D-Link devices using the following commands:

enable sflow
create sflow analyzer_server owner {timeout [ | collectorport | maxdatagramsize }
create sflow counter_poller ports [ | all] analyzer_server_id {interval [disable | ]}
config sflow counter_poller ports [ | all] interval [disable | ]

Example:

enable sflow
create sflow analyzer_server 1 owner MENFA {timeout infinite collector address <192.16.18.2> collector port <9996>

Here 192.16.18.2 is the IP address of the machine on which Site24x7 On-Premise Poller is installed (enter your machine's IP), 9996 is sFlow listener port, and datagram size is set at default of 1400.

create sflow flow_sampler ports all analyzer_server_id 1 rate 20

Here, the actual rate is the configured rate value multiplied by 256. For example, if the rate is 20, the actual rate 5120.

create sflow counter_poller ports all analyzer_server_id 1 interval 60
