Abstract

The invention provides a port training method and device. The method comprises the following steps of setting any target 10-gigabit port to be in a Down state and making the target 10-gigabit port send an error sequence ERR-WORD code stream when a port training state of the target 10-gigabit port is initialized; when a signal detect signal of the target 10-gigabit port is detected, carrying out port training on the target 10-gigabit port; and if the training is successful, setting the target 10-gigabit port to be in an UP state and controlling the target 10-gigabit port to stop sending the ERR-WORD code stream. Through application of the embodiments of the invention, the business exception of a specific application of opposite terminal equipment due to change of the UP / Down state of an opposite terminal port in a port training process can be avoided.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a port training method and device. Background technique [0002] In order to avoid the impact of link signal implementation differences on different devices (for example, different boards have different wiring), parameters such as pre-emphasis and amplitude in the sending and receiving direction need to be configured on the port for adjustment. For the sending direction, it is usually performed by software configuration. For the receiving direction, due to the unknowns and differences in the connection media (cables or modules, etc.) Mode, according to the received signal, automatically adjust the value of pre-emphasis, amplitude, EO (Eye Opening, eye height) and other values ​​in the receiving direction to ensure that the signal reaches the MAC (Media Access Control, Media Access Control) chip normally for data forwarding processing . [0003] In the prior art, ...
