1. A computer-implemented method, comprising:
receiving, by a first network device, a first error associated with the first network device;
generating, by the first network device, one or more first frames including first data indicative of the first error;
broadcasting, by the first network device, the one or more first frames to one or more neighboring network devices;
determining, after the broadcasting, that the first network device is unresponsive;
presenting the first data in response to a request to a second network device among the one or more neighboring network devices; and
configuring, by a network management system, an interval at which a plurality of network devices transmit frames that include device error data to neighboring network devices;
wherein the one or more first frames are broadcast prior to loading of an operating system of the first network device.
