Weird behaviour regarding SNMP table and information about stack ports

Votes:

0

Hello,

I am seeing some strange behaviour with my attempts to read the status of stack ports of stacked switches.

The OID of the table I am looking at is 1.3.6.1.4.1.2356.16.1.13.7.2

When I add this table I get an overview of all the stack ports, their status etc. and to which member of the switch stack they belong.

Something goes wrong when I make the sensors using the SNMP-custom table sensor. I have a stack of 5 switches, which means I should get 2 stack ports per switch with the right ID that inidicates to which switch the stack port belongs. When all the sensors are green, this ID is always that of just one switch.

PRTG ends up adding multiple sensors of the same stack ports, even though I selected 10 different ones.

Hello,

The channels created on a SNMP table sensor is dependent on what data the device is reporting back to us. You can check what data the device is sending with our SNMP Tester.

For a SNMP table please use the walk option with the root OID of the table.

Kind regards,

Hello,

I solved this. I was using the wrong index of the table, which resulted in the starnge behaviour. Using the first OID as an index solved the issue.
