Abstract
In some embodiments, an apparatus includes a switch device that can be operatively coupled to a network having a set of links. The switch device can receive at a first time, a message having a set of physical coding sublayer (PCS) lanes. The message can include an error notification within a first subset of PCS lanes from the set of PCS lanes and not within a second subset of PCS lanes from the set of PCS lanes. The error notification is associated with signal degradation of a link from the set of links, where the switch device can send a first signal in response to receiving the message at the first time. The switch device can also receive at a second time a message without the error notification, and the switch device can send a second signal in response to receiving the message at the second time.
