Cisco CBS350-48P-4G sFlow not showing up in PRTG




We just added CBS350-48P-4G to our network and were trying to get sFlows to show up in PRTG, for some reason the sflow sensor in PRTG reports no data being received, however running Wireshark on the PRGT server shows flows being received from the switch on UDP port 6343. sFlows packets in wireshark are showing up as v5.

Has anyone had any success with sFlow sensors and cisco CBS350 switches ?


cisco sflow udp v5

Hello there,

To verify if the PRTG host (or the host of the Remote Probe) is receiving proper and compatible Sflow packets, I would recommend to utilize our Sflow Tester Tool.

If you still encounter issues and do not receive any Sflow packets, please contact us via [email protected]

Kind regards,
