Abstract
A solution is provided wherein physical link parameters may be negotiated after a link is brought up by having the two devices involved in the link exchange identifiers when the link is initially brought up. These identifiers may be saved in the devices and then utilized upon receipt of subsequent physical link parameter negotiation packets to ensure that these packets are received by a partner who is connected via a physical link.
