Hi,

i have PRTG 13.3.6.3110+ in use. On several switches i want to monitor the traffic of a VLAN.

I can only monitor interface vlan's, but thats not what i want.

Is it even possible?

This is really dependent on the type of switch you have and whether or not this is possible with the MIB's that exist for it. For most switches, you will need to check with the manufacturer of the switch or take a look at their website and see if there are any SNMP counters which account for the VLAN traffic. If not, then it's not going to be possible. If so, then you will want to import those MIB's into PRTG with the MIB importer and then use a SNMP Library sensor to create that sensor.

I already imported MIBs with the MIB Importer, but can'f find anything in it to monitor VLAN Traffic.

The devices we use are: Cisco 6500, 4500, 3560.

You may want to do a walk on the device or try using the interfaces scan on the device to see if those counters exist for the IOS version and model that you are using.

Also, you may need to enable those counters on the device as well and with some Cisco switches you may have to take the traffic from individual ports and add it together.
