Monitoring via SNMP

We have a customer that would like to perform monitoring of their Peplink routers using Solarwinds and SNMP. They are currently working with a Max BR1. They wish to monitor data usage as well as set alerts in Solarwinds to notify them of usage on the equipment. I know that this can be done in IC2, but they would like to use Solarwinds. Has anyone done this in the past? They were able to get the device setup in the application, but it is not seeing the cellular interface. Is there anything that needs to be changed as far as configuration to accomplish this?

Are you using the custom MIBs? That should give visability of the cellular interfaces over SNMP.
