How to configure sFlow on LANCOM GS-2xxx switches

Before you begin, be aware that LANCOM GS-2xxx switches can support only one Auvik collector.

These instructions assume:

• The LANCOM switch is running GS-2xxx or higher.
• The date, time, and time zone are correctly set on the switch.
• You have administration access to the Lancom dashboard.
• You know the IP address of your Auvik collector.

Access the LANCOM web interface

1. Open a web browser and type in the switch’s IP address.
2. Log into the switch.

Configure sFlow

1. Log into the Lancom dashboard.
2. Go to Configurations > sFlow Agent > Collector.
3. Set the parameters:
   1. Collector IP: The IP address of your Auvik collector
   2. Port: Choose one of the following: 2055, 2056, 4432, 4739, 6343, 9995, or 9996.
   3. IP type: IPv4
   4. Time Out: 0 (Some LANCOM devices use 0 to indicate the sampling time never expires. If you’re not receiving flows after finishing the configuration, increase the timeout to its maximum value of 2147483647.)

4. Click Apply.
