摘要： Various methods and systems for preventing erroneous link aggregation due to component relocation are disclosed. Such methods include a method for changing the identifier used by a network device and communicating the identifier change to a peer network device without disrupting an aggregated link. In one embodiment, a method involves detecting an identifier change and sending a Port Aggregation Protocol (PAgP) protocol data unit (PDU) that includes a new identifier and information. The information indicates the identifier change. The new identifier identifies a network device subsequent to the identifier change. Another embodiment of a method involves detecting an identifier change and, subsequent to the identifier change, sending a link aggregation protocol PDU that includes an “old device identifier” field dedicated to conveying an old identifier. The old identifier identifies a network device prior to the identifier change.

摘要： Various systems and methods that allow multiple aggregation protocol sessions to be established in a daisy chain network are disclosed. One method involves sending a first aggregation protocol packet and a first session identifier associated therewith to a first network device via a first interface and sending a second aggregation protocol packet and a second session identifier associated therewith to a second network device via the first interface.

摘要： A system and method automatically configures the interfaces of an intermediate network device. A discovery process operating at the device detects the identity or type of network entities actually coupled to the device's interfaces. Utilizing the identity or type of detected entities, a look-up is performed to obtain a configuration macro specially defined for each detected network entity. The retrieved configuration macros are executed and applied at the respective interfaces. During operation, the intermediate network device continues to monitor the identity and type of entities actually coupled to its interfaces. If a change is detected, such as an entity moving from a first to a second interface, the specially defined configuration macro for that entity floats from the first to the second interface where it is executed and applied.

摘要： In one embodiment, a network device in a computer network determines a plurality of attribute events that each represent a virtual local area network (VLAN) registration state of a respective VLAN of a plurality of VLANs in the computer network. The plurality of attribute events are grouped into a plurality of sets of two or more attribute events. For each set of two or more attribute events, an encoded value is computed for the set with an encoding algorithm that encodes the two or more attribute events of the set into a single encoded value. Each of the plurality of encoded values is loaded within an attribute structure of a protocol data unit (PDU) message, such that the plurality of encoded values that encompass the plurality of VLANs are included within the attribute structure of the PDU message. The PDU message is transmitted to one or more other network devices.

摘要： A multiple instance spanning tree protocol (MI-STP) creates a plurality of active topologies (i.e., loop-free paths) within a computer network. These active topologies may be established through the exchange and processing of multiple instance spanning tree bridge protocol data unit messages (MI-STP BPDUs) by the intermediate network devices within the network. The active topologies are preferably created independently of any virtual local area network (VLAN) designations defined within the network. Once the active topologies are defined, each VLAN designation is then mapped to a single active topology, although multiple VLAN designations are preferably mapped to the same active topology to provide load balancing.

摘要： In one embodiment, a Talker device issues a Talker declaration for a stream. The Talker declaration has a declaration type that advertises the Talker device is offering the stream, and includes a stream ID that uniquely identifies the stream, an indication of resource requirements of the stream, and an indication of a priority of data frames belonging to the stream. The Talker device receives a Listener Declaration from a Listener device of one or more Listener devices. The Listener declaration includes the same stream ID as the Talker declaration and has a declaration type that indicates at least one Listener device is ready to receive the stream and that sufficient resources to meet the resource requirements of the stream have been allocated at one or more intervening bridges that received both the Talker declaration and the Listener declaration. In response the received Listener declaration, transmission of the stream is begun.
