Abstract

The invention discloses a port physical link state detection method and system with an external PHY chip. The method comprises the following steps: determining a port of which the physical link state is to be detected; establishing and storing a mapping relationship between the MAC port of the port and the external PHY port; obtaining a link state of a line side of an MAC port of the port and a link state of a line side of an external PHY port; and determining the actual link state of the port according to the mapping relation and the link states of the line sides of the MAC port and the external PHY port of the port. The system comprises a port determination module, a mapping relation establishment module, a Link state acquisition module and an actual link state determination module. According to the invention, the detection efficiency of the port physical link state and the accuracy of the detection result can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of switch port status detection, in particular to a method and system for detecting the physical link status of a port with an external PHY (PhysicalLayer, physical layer) chip. Background technique [0002] In current switch products, most switch devices use an external PHY chip for port expansion. For these switches using external PHY chips, it is an important technical issue to detect the physical link status of their ports so as to ensure the normal operation of data forwarding services. [0003] The current method for detecting the physical link status of a switch port with an external PHY chip is usually to save the corresponding cable module information and perform targeted processing. Specifically, when the link (connection) status on the MAC (MediaAccess Control) side of the switch port is inconsistent with the link status on the line side of the external PHY, many cable modules will be i...
