Description
Devices can find their startup configuration either in their own NVRAM or access it over the network via TFTP or Remote Copy (rcp). Loading the image from the network is taking a security risk since the image could be intercepted by an attacker who could corrupt the image resulting in a denial of service. Configuration auto-loading can be enabled when the device is connected to a non-operational network. Once the device is connected to an operational (i.e. production) network, configuration auto-loading must be disabled.
