Setup Master Control Node (MCN)

The SD-WAN Master Control Node is the head end appliance in the Virtual WAN. Typically, this is a 4000 or 5100 Virtual WAN appliance deployed at the Enterprise data center. The MCN serves as the distribution point for the initial system configuration and any subsequent configuration changes. In addition, you conduct most upgrade procedures through the Management Web Interface on the MCN. There can be only one active MCN in a Virtual WAN.

By default, appliances have the pre-assigned role of client. To establish an appliance as the MCN, you must first add and configure the MCN site, and then stage and activate the configuration and appropriate software package on the designated MCN appliance.
