  • Link layer discovery protocol (LLDP) on multiple nodes of a distributed fabric
    Patent number: 9743367
    Abstract: In one embodiment, a method for providing link layer discovery protocol (LLDP) to a distributed fabric includes sending a neighbor synchronization request message from a master node to one or more member nodes connected to the master node, the neighbor synchronization request message including a request for a recipient member node to send its LLDP neighbor information to the master node, receiving a neighbor synchronization update message at the master node from at least one of the one or more member nodes, the neighbor synchronization update message including information about local LLDP neighbors of the one or more member nodes, and storing the information about the local LLDP neighbors from the at least one of the one or more member nodes in a LLDP neighbors database of the master node.

  • Management of routing tables shared by logical switch partitions in a distributed network switch
    Patent number: 9246802
    Abstract: Techniques are provided for managing a routing table in a distributed network switch. The distributed network switch is divided into logical switch partitions, or logical networks, that may share a routing table. The shared routing table is configured with counters and thresholds to control utilization of the routing table on a per-logical network basis. When counters exceed certain threshold, the routing table is modified to reduce routing entries within the routing table or pause insertion of new routing entries.
