Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] figure 1 It is the basic structural diagram of the present invention. In the figure, reference numeral 10A shows the network device in question. The device to communicate with is shown by reference numeral 10B.

[0035] The network device 10A is a network device with an Ethernet interface, and is interconnected with the device 10B through auto-negotiation. The device 10A is characterized in that link establishing means 11 and on / off setting means 12 are provided as shown. Specifically, the link establishing means 11 is used to forcibly establish a link 13 with another device 10B, and the on / off setting means 12 is used to set the function on / off of the link establishing means 11 .

[0036] By setting the on / off setting means 12 to ON, the link establishing means 11 built in the network device 10A starts operating, thereby avoiding th...

Abstract

A network device provided with an Ethernet interface for interconnecting with another network device by auto negotiation, the network device comprising a link establishing function unit compulsorily establishing a link with the other network device and an on / off setting function unit setting the function of the link establishing function unit on or off and the link establishing function unit being comprised of a data transmission suppressing unit for suppressing the transmission of user data to the other network device until the sequence based on the auto negotiation is finished, whereby the problem of connectivity where the sequence of the auto negotiation repeats and no link can be established is solved.

Description

technical field [0001] The present invention relates to a layer 2 / 3 switch, a transmission device or other network equipment (Ethernet equipment) with an Ethernet (Ethernet, registered trademark, the same below) interface, more specifically, relates to a layer 2 / 3 network (operator mainly A network device designed to enhance the operation of the auto-negotiation features it supports is used in the introduction of new services on such networks. Note that the auto-negotiation function is a function of automatically selecting a communication mode between network devices, and is defined by IEEE802.3. Background technique [0002] In recent years, as data communication bandwidths and speeds have increased, so has the demand for services provided by inexpensive Ethernet interfaces that can accommodate user interfaces. [0003] Currently, the Ethernet interface used by the connection operator needs to use the auto-negotiation function defined by IEEE802.3. This auto-negotiation f...
