Update Global DNS on RV50X

Can anyone suggest the best way to update Global DNS settings on multiple RV50X devices that are out in the field (ssh and GUI access available).
Thanks

Hi @govind.varsani,

Please refer to the Global DNS section on page 142 of the AirLink RV50/RV50X Software Configuration Guide, which can be found at the following link: https://source.sierrawireless.com/resources/airlink/software_reference_docs/airlink-rv-series---configuration-guide/#sthash.2IUh8iVb.dpbs

Thanks,
