The present invention describes a method, system and mirror driver for discarding data frames in mirrored data communication networks. In the method, at least one data structure comprising one or more entries is created and maintained, an entry comprising at least a current sender data frame sequence number. When a data frame is received, a hash code is computed using then sender address and the receiver address of the received data frame, the hash code being an index to the table. The current sender data frame sequence number is checked in the entry indexed by the computed hash code, and if the sequence number of the received frame is smaller than the current sender data frame sequence number in the entry, the data frame is discarded as being a duplicate frame.
