Device, network switching equipment and method for realizing port configuration

Abstract

The invention discloses a device, network switching equipment and a method for realizing port configuration. The device comprises a sampling logic unit, a plurality of port filtering registers, and an interrupt register, wherein the sampling logic unit is used for sampling port state signals transmitted by a plurality of ports respectively; the plurality of port filtering registers are used for recording preset high-level identification when the result of the sampling of the corresponding port state signal in the current period by the sampling logic unit is effective high level and recording preset low-level identification when the result of the sampling of the corresponding port state signal in the current period by the sampling logic unit is effective low level; and the interrupt register is used for reporting an interrupt request signal to a central processing unit (CPU) when monitoring high and low level identification change of data stored by the port filtering registers. The device, network switching equipment and the method reduce the occupation of CPU and bus resources in the conventional port configuration process to the maximum extent and guarantee the rapid switching performance of the network switching equipment.

Description

technical field [0001] The invention relates to the field of network switching equipment, in particular to a device for realizing port configuration, network switching equipment and a method. Background technique [0002] In the prior art, when the network switching device has a cable plugging operation or the peer device changes the speed or changes the duplex mode, the port status (connection, speed, duplex, etc.) of the network switching device switching module will change accordingly , at this time, the network switching device needs to re-configure the port of the switching module before continuing to communicate. [0003] In the existing port configuration mode, the CPU of the network switching device generally actively polls the status of each port periodically and regularly to determine whether each port has a port configuration requirement, so as to perform corresponding configuration services. As the network switching device The number of ports of the switching mo...
