How to configure sFlow on NETGEAR switches

Follow

These instructions assume:

  • XSM7224S firmware version 9.0.1 or higher is installed.
  • Firmware version 10.0.0.x or higher is installed.
  • The date, time, and time zone are correctly set on the switch.
  • You have Telnet or SSH credentials and access to your switch.
  • You know the IP address of your Auvik collector.

Access the switch CLI

  1. Telnet or SSH into your switch.
  2. Enter privileged mode by typing enable and entering your enable password.

Configure sFlow

Run the following command. Replace <AuvikCollectorIP> with the IP address of your Auvik collector.

sflow receiver 1 ip <AuvikCollectorIP>

Configure sampling port

Configure the sFlow receiver index, sampling rate, and sampling maximum header size for the sampling port. Repeat these for all the ports to be sampled.

sflow sampler 1
sflow sampler rate <128,256,512,1024>
