    摘要： Disclosed are mechanisms for facilitating the use of DHCP (dynamic host configuration protocol) binding data. In general, certain applications include mechanisms for intercepting data being sent from a node and then determining whether the data corresponds to a valid IP address and MAC address binding. Embodiments of the present invention provide mechanisms for sharing such DHCP binding data between routers (or other type of network devices) in a redundancy group so that any of the routers may take over the data inspection to validate DHCP bindings. In particular aspects of the invention, the DHCP binding data is validated in procedures related to DHCP snooping, dynamic ARP (address resolution protocol) inspection, and the like.

    摘要： Methods and apparatus are disclosed for performing lookup operations using associative memories, including, but not limited to modifying search keys within an associative memory based on modification mappings, forcing a no-hit condition in response to a highest-priority matching entry including a force no-hit indication, selecting among various sets or banks of associative memory entries in determining a lookup result, and detecting and propagating error conditions. In one implementation, each block retrieves a modification mapping from a local memory and modifies a received search key based on the mapping and received modification data. In one implementation, each of the associative memory entries includes a field for indicating that a successful match on the entry should or should not force a no-hit result. In one implementation, an indication of which associative memory blocks or sets of entries to use in a particular lookup operation is retrieved from a memory.

    摘要： Methods, apparatus, and other mechanisms are disclosed for merging lookup results, such as from one or more associative memory banks and/or memory devices. An access list is identified. A first set of entries corresponding to a first feature of the access control list entries and a second set of entries corresponding to a second feature of the access control list entries are identified. First and second associative memory banks are programmed respectively based on the first and second sets of entries. Lookup operations are then typically performed substantially simultaneously on the first and second sets of associative memory entries programmed in the associative memory banks to generate multiple lookup results, with these results typically being identified directly, or via a lookup operation in an adjunct memory or other storage mechanism. These lookup results are then combined to generate a merged lookup result.

    摘要： Systems and methods are provided for using fabric port-channels for Switched Virtual Interfaces (SVIs) to scale IP connectivity for hosts in directly connected subnets in massive scale data centers. By representing SVIs by internal fabric port-channels, ToRs hosting the SVI can share routed traffic directed toward hosts within the associated vlan in a load-balanced manner without frequent updates to the FIB/Adjacency tables.
