摘要： Disclosed are, inter alia, methods, apparatus, data structures, computer-readable media, mechanisms, and means for supporting a large number of virtual local area networks (VLANS) in a bridged network. Packets are received that include 802.1Q Virtual Local Area Network (VLAN) identifiers (VIDs). However, rather than accessing the VLAN forwarding information directly based on the VID as conventionally performed, the VLAN forwarding information to use for a particular packet is determined based on an interface (e.g., virtual or physical interface, port, MPLS label, GRE tunnel or other abstraction of the interface). In other words, the interface associated with the packet identifies a context for determining the VLAN forwarding information based on the VID included in the packet. Therefore, network bridging devices can support more VLANs than that imposed by the 4096 possible values of a VID.

摘要： Methods, apparatus, and other mechanisms are disclosed for generating accounting or other data based on that indicated in access control lists or other specifications, and typically using associative memory entries in one or more associative memory banks and/or memory devices. One implementation identifies an access control list including multiple access control list entries, with a subset of these access control list entries identifying accounting requests. Accounting mechanisms are associated with each of said access control list entries in the subset of access control list entries identifying accounting requests. An item is identified, and a corresponding accounting mechanism is updated. In one implementation, the item includes at least one autonomous system number. In one implementation, at least one of the accounting mechanisms is associated with at least two different access control list entries in the subset of access control list entries identifying accounting requests.
