Dynamic network device configuration
A dynamic configuration system can manage and configure switches or other network devices that come online in a network. When the dynamic configuration system determines that a network device has come online, the dynamic configuration system can identify the network device (e.g., based on its network location, neighbors, fingerprint, identifier, address or the like), select the appropriate configuration data for the network based on the desired network topology, and transmit the configuration data to the network device. The network device can then load the configuration data and function as a component of the desired network topology.
