Abstract:
1. A method for identifying and processing secure data frames flowing between a source port and a switch port in a network, the method comprising: receiving a data frame from the source port; detecting network address of the source port; searching for an entry corresponding to the network address of the source port in a forwarding table; categorizing the data frame as a secure data frame or a non-secure data frame on the basis of the entry in the forwarding table; allowing access to the secure data frame; and redirecting the non-secure data frame by updating the value of a notifying bit using a RED_SEC_MOVE register, redirecting the non-secure-data frame to a receiving port or a notification port based on the value of the notifying bit; examining the non-secure data frame at the receiving port, updating the forwarding table if the examined non-secure data frame is found to be a secure data frame; and dropping the non-secure data frame if the examined non-secure data frame is found to be a non-secure data frame.
