A network switch is configured to receive packet data. The network switch includes a memory and a processor. The memory is configured to store an access control list and an abnormity detecting program, filter the packet data according to the access control list, and perform an abnormity detecting procedure on the packet data according to the abnormity detecting program. When at least one abnormity event occurs in one of a plurality of time intervals, a counting value increases. When the counting value reaches a counting threshold value, the memory sends an abnormity notification to the processor and the processor performs an abnormity processing procedure on the packet data.

Network switch and abnormity detecting method

A communication device includes a transceiver and a control circuit. The control circuit determines whether to transmit a second MKPDU in advance according to a member identifier of a peer device carried by a received first MKPDU and one or more lists maintained by the communication device. When the member identifier of the peer device is not recorded in the one or more lists, the control circuit determines to transmit the second MKPDU in advance. When the control circuit determines to transmit the second MKPDU in advance, the control circuit generates the second MKPDU, encodes the second MKPDU to generate a frame, and transmits a signal carrying the frame through the transceiver, wherein a time interval between the transmission of the signal and a previous transmission performed by the transceiver is less than a predetermined transmission period.

Communication device and method for accelerating device discovery and identification

A method used in a stacking/stackable switch unit includes: providing a plurality of signal ports of the stacking/stackable switch unit, the signal ports having at least one master/slave control port corresponding to at least one operation function of the stacking/stackable switch unit; during a boot-up procedure, automatically determining whether the stacking/stackable switch unit is a master or a slave according to at least one signal level of the at least one master/slave control port and/or content of at least one bit obtained from the at least one master/slave control port.
