We are about to migrate our PRTG install from a workstation level machine to a server. With many of our msot important servers, we setup 2 Gbps links from the core network switch using LACP.

Is the use of LACP, or multiple NIC trunking supported on the PRTG core server..?

Dear Arnold,

PRTG has no special code implemented to handle LACP trunks. As long as the implementation is transparent to the application-level you should not be face with problems.

Kind regards

Please supply an example of how to add a LACP sensor.

Hello John, thank you for your reply.

As Dieter mentioned, PRTG has no special code implemented to handle LACP trunks. Also, each vendor may chose to perform a different implementation. Usually the easiest approach is to deploy an "SNMP Traffic sensor" and select the two member interfaces and the logical LACP interface (if available).

However, you may not see any traffic on the LACP, in this case create a new Sensor Factory Sensor to aggregate the data from both interfaces.

However, the best alternative is to contact the vendor and ask for input/recommendations for monitoring the LACP with SNMP. The standard IF-MIB does not define how logical interfaces such as LACP/LAG trunks should be reported, the implementation will vary depending on the vendor.

Some vendors may also have private SNMP implementations for this. In this case you may want to import the MIB:
