Each port interface circuit preferably supports multiple virtual local area network (VLAN) designations and associates those VLAN designations with data frames transmitted to and from the switch over the link. The CBL mechanism cooperates with a forwarding engine of the switch to selectively enable the port interface circuit to receive certain VLAN-designated frames, and to discard others, in an efficient and cost-effective manner.Field of SearchUsing a particular learning algorithm or techniqueSpanning tree In a bus system Having a plurality of nodes performing distributed switching Bridge or gateway between networks Bridge between bus systems Star configuration Having a signaling feature Particular switching network arrangement Processing of address header for routing, per se Ring or loop forms backbone for interconnecting other networks Plurality of rings or loops to form a mesh network Nodes interconnected in hierarchy to form a tree | |
