Have the ability to configure a 2nd DNS in Netreo

Would like to see the ability to configure a secondary DNS in netreo .

Use case:

If you have a # of devices added to Netreo via hostname and the primary DNS server goes down we are going to get host downs for all of those devices. However, if we were able to configure a secondary DNS server that would be used in case the Primary DNS was unreachable we would be able to prevent the false Host down alerts that would be generated from not being able to resolve the host name.
