Problems solved by technology

A faulty device may also fail to forward frames containing valid information
In addition, the faulty device may not be able to connect to other components in the network at the proper speed (such as 10 or 100 megabits per second) or with the proper settings (such as full-duplex or half-duplex)

Embodiment Construction

[0014] Figure 1 illustrates an example communication network 100 according to one embodiment of the present disclosure. The embodiment of communication network 100 shown in FIG. 1 is for illustration only. Other embodiments of the communication network may be used without departing from the scope of the present disclosure.

[0015] In the example embodiment, communication network 100 includes a plurality of switches 102a-102d and a plurality of endpoints 104a-104e. The switches 102a-102d communicate and transfer information between the various endpoints 104a-104e. For example, switch 102a may receive information from endpoint 104a and send the information to switch 102c, which may receive the information and forward it to one or more of endpoints 104c-104e. Depending on the layout of the network 100, each of the switches 102a-102d is typically capable of forwarding traffic between one or more of the endpoints 104a-104e and / or one or more other switches. Each of the switches...

Abstract

A method includes performing one or more tests at a network component. The network component is capable of transmitting frames of information in a network. The network component is also capable of enabling and disabling the transmitting of frames. The method also includes detecting a failure of at least one of the one or more tests. In addition, the method includes at least one of not enabling the transmitting of frames by the network component and disabling the transmitting of frames by the network component in response to the detected failure. As an example, the one or more tests may be performed in response to the network component powering on. The network component may be initially disabled from transmitting the frames, and the transmitting of frames is not enabled in response to the detected failure.

Description

technical field [0001] The present disclosure relates generally to communication networks, and more particularly, to an apparatus and method for preventing network errors. Background technique [0002] Communications networks, such as computing networks, routinely use switches, routers, and other devices to transfer information across the network. Each of these devices typically receives information in the network and recognizes the destination of the information. Each of the devices then typically forwards the information directly to the destination, or indirectly through one or more other devices. [0003] Occasionally, switches, routers, or other devices in communication networks fail. There are often many possible causes for a failure, including a loss of power to the device or a hardware or software failure of the device. When a device such as a switch or router fails, the failure may cause false, incorrect or excessive network traffic to propagate across the communi...
