Abstract
In an example embodiment, a beacon is sent on all available interfaces of a device comprising data indicating the operating parameters of all interfaces of the device. A beacon containing data about the configuration of a first interface and a second interface is sent on both the first interface and the second interface. The beacon may suitably comprise data indicating the protocol, channel, and spanning trees for the interface. If communication on the primary interface becomes unavailable, the data in the beacons can be used to facilitate switching communication to the secondary interface.
