Embodiment Construction

[0025] A device for implementing port configuration, a network switching device, and a method for implementing port configuration provided by embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] Firstly, the structure and working principle of an apparatus for implementing port configuration provided by an embodiment of the present invention will be described in detail.

[0027] Such as figure 1 As shown, the device for implementing port configuration provided by the embodiment of the present invention includes: a sampling logic unit 101, an interrupt register 102, and at least one port filter register ( figure 1 Take port filtering registers 103 and 104 as an example); Wherein:

[0028] The sampling logic unit 101 is used to sample port state signals output by multiple ports respectively; in other words, the sampling logic unit 101 is used to periodically convert the time-continuous port state signals int...

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...
