Example Embodiment

[0031] Refer to Figure 4 As shown, the device of the present invention includes a media access control (MAC) module, a serial independent media interface / source synchronous serial independent media interface module (ie a serial independent media interface or a source synchronous serial independent media interface module, referred to as SMII / SS-SMII module), data input / output management module (abbreviated as MDIO module) and selection control module. The serial independent media interface / source synchronous serial independent media interface module is connected to the MAC module and the external physical layer chip, and the data input / output management module is connected to the external physical layer chip through the interface for obtaining from the physical layer chip PHY Status information; the irrelevant media interface module and the data input / output management module are respectively connected to the selection control module to report the acquired status information; the ...

Abstract

This invention discloses a method and a device for supporting Ethernet interface self negotiation in medium access control. The method includes: a data input/output manage module and a serial irrelevant medium interface module synchronized to its interface/source fetch a first and second set of state information from each physical port and separately report them to a select and control module which selects one set of state information to its corresponding medium access control module to switch the working states. The device includes: a medium acc control module, a serial irrelevant, medium interface module synchronized to its interface/source, a module data input/output manage module and a selection control module.

Description

technical field [0001] The invention relates to medium-independent interface technology in communication, in particular to a method and device for supporting Ethernet port self-negotiation in medium access control. Background technique [0002] The auto-negotiation function in the Ethernet switch is realized by the physical layer (PHY) chip. Through self-negotiation, two connected PHY chips can determine the current working status, including link status (linkup / link down), speed status (10M / 100M) and duplex status (half duplex / full duplex). [0003] refer to figure 1 As shown, only when the working state of the medium access control (MAC) of the Ethernet switch is consistent with the working state of the PHY chip, can the normal progress of frame exchange be guaranteed. However, the MAC itself does not have the self-negotiation function, and can only obtain the result of the self-negotiation from the PHY chip as the working state of the MAC, that is, the method of supporti...
