How to configure sFlow on Dell PowerConnect and N Series switches

Follow

These instructions assume:

  • The date, time, and time zone are correctly set on the switch.
  • You have Telnet or SSH credentials and access to your Dell PowerConnect or N Series switches.
  • You know the IP address of your Auvik collector.

Access the switch CLI

  1. Telnet or SSH into the 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, and <AuvikPort> with one of the following port numbers: 2055, 2056, 4432, 4739, 6343, 9995, or 9996. 

For the third and fourth lines, you’ll need to determine the port address range for which you’d like to export flow. For example, for a 16-port single chassis switch, you’d use 1/g1-1/g16.

sflow 1 destination <AuvikCollectorPort> <AuvikPort>
sflow 1 destination owner 1 timeout 60 # Configuration for PowerConnect
sflow 1 destination owner 1 timeout 60 # Configuration for N-Series
sflow 1 polling Ethernet 1g1-1/g16
sflow 1 sampling Ethernet 1/g1-1/g16 <128,256,512,1024>
exit
end

Confirm the settings

Run the following command to confirm the configuration: 

show sflow 1 destination 
show sflow 1 polling 
show sflow 1 sampling
