GraphingTX/RX on Vlan Power connect 5424

Hi, 

We recently started using Observium as networkgraphing solution, and it uses SNMP to retrieve transferdata for the physical ports, but it is unable to get it for the VLANs, is it even possible in the firmware to do that?

The data for the physical ports work great, and i just want to check if it is possible before i spend too much time trying to get it to work.
