    摘要: Techniques are provided for managing and distributing communications in a network. At a first switch device arranged in a first configuration in a network, a set of one or more network attributes are determined, which are associated with network communications that the first switch device is interested in receiving from other network devices. The first switch device sends to a controller device an attribute interest message that informs the controller device of the set of network attributes. The first switch device receives a mapping of the network attributes in to one or more identifiers. The identifiers are included in a header of subsequent frames sent in the network. An identifier interest message is then sent to a second switch device arranged in a second network configuration in the network to inform the second switch device of identifiers of the network attributes of which the first device has an interest.

    摘要: In one embodiment, one or more indicia of stress are monitored. Based on the one or more indicia of stress, it is determined a stress condition exists. In response to the stress condition, one or more link aggregation actors and partners are caused to enter a grace state for a grace period. While the one or more link aggregation actors and partners are in the grace state, link aggregation formation is paced on a plurality of links by delaying formation of one or more new link aggregation groups on the plurality of links until a hold is released. Upon expiration of the grace period, the grace state is exited.

    摘要: Synchronization of traffic multiplexing in link aggregation is described. In an embodiment, a first link aggregator and a second link aggregator are associated with a plurality of links. The first link aggregator maintains an identifier for each link indicating at least a state of enabled or disabled. A synchronized clock is established between the first link aggregator and the second link aggregator. A particular link of the plurality of links is transitioned. Wherein, the transitioning is performed by the first link aggregator sending, to the second link aggregator, a first message identifying a particular time to transition the particular link. The first link aggregator receives, from the second link aggregator, a second message indicating that the particular time is acceptable. In response to a determination that the second message indicates that the particular time is acceptable and that the synchronized clock has reached the particular time, transitioning the link.

    摘要: In one embodiment, a multiple spanning tree (MST) region is defined in a network, where the MST region includes a plurality of network nodes interconnected by links. A MST cluster is defined within the MST region, where the MST cluster includes a plurality of network nodes selected from the plurality of network nodes of the MST region. A network node of the MST cluster generates one or more MST bridge protocol data units (BPDUs) that present the MST cluster as a single logical entity to network nodes of the MST region that are not included in the MST cluster, yet enables per-multiple spanning tree instance (per-MSTI) load balancing of traffic across inter-cluster links that connect network nodes included in the MST cluster and network nodes of the MST region that are not included in the MST cluster.

    摘要: In one embodiment, a protocol state associated with a port of a network device is determined to have expired. A port group of which the port is a member is determined, the port group including ports that share one or more common characteristics. A policy is applied to the ports of the port group to determine whether one or more other ports in the port group also have a corresponding protocol state protocol that has expired. In response to one or more other ports in the port group also having a corresponding protocol state that has expired, expiration of the protocol state is determined to be a false positive and no further action is taken based on expiration of the protocol state. When expiration of the protocol state is not determined to be a false positive, further action is taken based on expiration of the protocol state.

    摘要: In one embodiment, a first number of multiple spanning tree instances (MSTIs) are defined within a network. A second number of network segments associated with segmentation identifier (IDs) are also configured, where the first number of MSTIs is less than the second number of segmentation IDs. Segmentation ID to MSTI mappings are maintained that map each defined segmentation ID of the second number of network segments to one of the first number of MSTIs. A segmentation mapping digest is computed of the segmentation ID to MSTI mappings. Multiple spanning tree (MST) bridge protocol data units (BPDUs) are broadcast that include the digest of the segmentation ID to MSTI mappings.
