    Abstract: Presented herein are systems, and methods thereof, that is configured to enter a maintenance mode to isolate itself from its neighbor and to gracefully cause neighbor devices to isolate themselves from the system, as to cause minimal or “zero” service disruption with its neighbors. The system broadcasts a maintenance-related message, via a standard transport layer, over routing protocols, to counter parts protocols at the neighbor device and waits for an acknowledgement message from the neighbor network devices. The broadcast and acknowledgement, through standard transport layer messaging, ensures that traffic generated by such protocols at the neighbor devices, regardless of manufacturer, are redirected before the system fully enters into the maintenance mode.

    Abstract: An example method for diagnosis and throughput measurement of FC ports in a SAN environment is provided and includes generating, by a control processor at a generator in the SAN, a control packet requesting a link test to be performed with a reflector in the SAN, sending the control packet to the reflector through a media access controller (MAC) of the generator, receiving, at the MAC of the generator, an acknowledgement from the reflector indicating ability to perform the requested link test, generating, at the MAC of the generator, a test data packet for the link test, performing the link test with the reflector, and analyzing, at the generator, network parameters based on results of the link test.

    Abstract: Methods and systems are described herein for graceful insertion and removal of at a data link layer of an open systems interconnection model (OSI Model). In one aspect, the method comprises: establishing connections to at least two ports on a first side of a link to create a link aggregation group managed using link aggregation control protocol (LACP), wherein the link aggregation group constitutes a transmit path from the first side of the link to the second side of the link. A partner device may receive, from a first port of the at least two ports, a first message, wherein the first message indicates that the first port will become unavailable to receive traffic.
