How to configure sFlow on 3Com switches

These instructions assume:

• The date, time, and time zone are correctly set on the switch.
• You have Telnet or SSH credentials and access to the switch.
• 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. Replace <deviceIP> with the IP address of the device where you’d like the packets to originate.

sflow agent ip <deviceIP>
sflow collector ip <AuvikCollectorIP> port <AuvikPort>
sflow version 9
sflow interval 60

Then, configure each interface for which you want to send sFlow:

interface <interface name, i.e: ethernet 1/0>
sflow enable <inbound/outbound/both>
sflow sampling-mode random
sflow sampling-rate <rate, 128, 256, 512, 1024>

Confirm the settings

Run the following command to confirm the configuration: 

display sflow
