Hi Chris,

Thank you for writing to us. We are currently working on a feature that monitor Routers, Switches and Firewall in Site24x7 using SNMP. Using this feature you can monitor performance of Routers, Switches and Firewall and also the  bandwidth (Rx and Tx). This feature will be available as closed beta1 early access before mid of June2015.

We will keep you posted once closed beta1 early access is available.

Thanks and Regards,
Praveen Kumar
