When ever i try to add traffic sensor to monitor my cisco sf300-24 switch i am getting the below error
"Sensor does not get response from device. SNMP credentials are wrong or device does not support the required uptime OID (220.127.116.11.18.104.22.168.0) for traffic sensors. This OID is mandatory by the SNMP RFC. Check SNMP access rights or contact device vendor. (code: PE244)"
i tried the PRTG "snmp tester" and tested for uptime.There it show the the correct uptime.please advice to resolve the issue.
