Systems and methods are disclosed for effectuating control-plane changes at increased speeds to protect a network in which switching operations are performed. Operations to effectuate control-plane changes in the network can be divided between software and more-rapid, dedicated hardware within a line card. Examples of operations reserved to hardware implementation can include blocking and unblocking of ports, flushing of learned entries from switch tables, and coordination of control-plane changes through the generation of messages sent between nodes, and also between line cards of a node. Determinations about the need for hardware-driven, control-plane changes may be made based on events occurring in the network in accordance with any of a number of different network protection protocols. The protocol may be implemented in a state machine and the software may determine the state of the hardware through a master/slave relationship.

A method and apparatus for implementing a virtual local area network. The method includes determining a global virtual local area network for transmitting a data frame in response to receiving the data frame at a first switch, encapsulating the data frame based at least in part on said determination and transmitting it to at least one second switch over the determined global virtual local area network. The data frame is received at the second switch and an identifier of the global virtual local area network is obtained according to the data frame. Based at least in part on the identifier of the global virtual local area network, it is determined that which local virtual local area network served by the second switch the de-capsulated data frame can be sent to.
