Abstract

Methods and switch devices for switching data frames are described. A method performed by a source switch device may include receiving a data frame from a source host node, wherein the data frame includes a MAC address of the source host node and a destination MAC address; modifying the received data frame by modifying a part of the source MAC address in the received data frame with information comprising: the switch ID, a port number and a reference number; and determining if there is a table in the source switch device. Further, if the received data frame is an ARP request message, the method may include modifying the modified data frame by replacing a sender MAC address with the modified part of the source MAC address and flooding the further modified data frame, to at least one switch device.
