Abstract
Method for detecting link partner state during Auto Negotiation then switching local state to establish link. A method is disclosed for allowing a host network node to establish a compatible communication link with a link partner network node disposed on the opposite end of a physical communication link from the host network node. The host node monitors data traffic received from the link partner network node. The host node then determines from the monitored data traffic from the link partner network node if the link partner network node is requesting configuration information from the host network node. If a request for configuration information is received from a link partner network node, then the host network node is operable to facilitate an exchange of configuration information with the link partner network node to determine if each of the host network node and link partner network node have common communication capabilities that can be configured to allow compatible communication there between over the physical communication link. After either an exchange of configuration information is made and a common configuration is determined at each of the host network node and the link partner network node, or a default configuration is established, then transferring data from the host network node to the link partner node.
