Description
Technical Field
The invention relates to the field of network equipment, in particular to a method and a device for a COMBO interface to adapt to an Ethernet interface.
Background
COMBO interface (optical-electrical multiplexing interface) refers to two ethernet physical interfaces (one is an optical port and one is an electrical port) types disposed on a device panel of a network device. However, because only one MAC exists inside the network device, and the MAC can only form a path with one ethernet physical interface of the COMBO interface at the same time, the optical interface and the electrical interface of the COMBO interface cannot work simultaneously, that is, when one of the COMBO interfaces is activated at a certain time, the other interface is automatically in a disabled state. When two network devices in the same group of networks need information interaction, the type of the working interface of the COMBO interface of the local network device needs to be consistent with that of the working interface of the opposite network device. The existing network device negotiates the interface type with the opposite terminal network device mainly in a self-adaptive manner. For example, when the media currently in effect of the COMBO interface of the local network device and the media currently in effect of the peer network device are both optical media, the configuration of the COMBO interface of the local network device is automatically switched to Fiber (optical mode), and when the media currently in effect of the COMBO interface of the local network device and the media currently in effect of the peer network device are both dielectric media, the configuration of the COMBO interface of the local network device is automatically switched to Copper (electrical mode), without user intervention.
At present, the COMBO interface of the local network device and the currently effective medium of the opposite network device are ensured to be the same mainly through the following two adaptive modes: one is that the media types which are valid by the COMBO interface of the local network equipment are periodically switched, and when the valid media types of the interfaces at the two ends are consistent, the matching is considered to be successful; the other method is to deduce the effective media type of local COMBO interface according to whether the optical module on the optical port of the local COMBO interface is in place, and then the in-place is set as Fiber, and the out-of-place is set as Copper, so as not to match the media type of the opposite network device interface.
However, the mode of switching the effective media types of the COMBO interface of the local network device needs the COMBO interface of the local network device and the interface of the opposite network device to collide at the same time point, so that the effective media types of the interfaces at the two ends can be successfully matched, the matching time of the effective media types of the interfaces at the two ends is not controllable, and the operation cost of the network device can be increased if the media types of the COMBO interface of the local network device are continuously switched; the network device directly configures the local COMBO interface as Fiber without considering the working state of an optical module connected to the optical port of the local COMBO interface as long as the optical module of the local COMBO interface is in place, for example, at this time, an electrical module connected to the electrical port of the local COMBO interface is in a working state, and the local COMBO interface is still configured as Fiber, which is not favorable for realizing the self-adapting function of the COMBO interface.
Disclosure of Invention
The embodiment of the invention provides a method and a device for a COMBO interface to adapt to an Ethernet interface, which solve the problem that the self-adapting result of the COMBO interface of the existing network equipment is inaccurate when the COMBO interface works in a self-adapting mode.

Optionally, the obtaining module is configured to obtain current LOS signal state information of an optical module connected to the COMBO interface if the COMBO interface and the opposite-end ethernet physical interface are in a non-connection link state;
the determining module is configured to determine, according to the LOS signal state information acquired by the acquiring module, a type of a target port that the COMBO interface should take effect;
the matching module is used for matching the target port type determined by the determining module with the currently effective port type of the COMBO interface and determining whether to switch the currently effective port type of the COMBO interface.
According to the method and device for the COMBO interface self-adaptive Ethernet interface provided by the embodiment of the invention, when the COMBO interface and the opposite-end Ethernet physical interface are in a non-connection link state, the current LOS signal state information of an optical module connected with the COMBO interface is obtained, then the type of a target port which should be taken into effect by the COMBO interface is determined according to the LOS signal state information, and the type of the target port is matched with the type of the port which is taken into effect by the COMBO interface at present, so that whether the type of the port which is taken into effect by the COMBO interface at present. Therefore, whether the optical module receives the optical signal currently is judged according to the LOS signal state information of the optical module connected with the COMBO interface, the target port type which the COMBO interface should take effect is further obtained, the target port type is further matched with the port type which the COMBO interface takes effect currently, and whether the port type which the COMBO interface takes effect currently is switched is determined. The method for judging the connection condition of the optical medium of the optical port of the COMBO interface by using the LOS signal enables the network equipment to be more accurate and efficient when the self-adaptive function of the COMBO interface is realized.

LOS (English, Chinese: LOSs Of Signal) Signal, when the receiving power Of the optical module is lower than a certain threshold value in a certain time, the LOS Signal is in an LOS Signal generating state, which indicates that the optical Signal is lost. Specifically, the LOS signal is generated when the COMBO interface does not receive the optical signal generated by the opposite-end interface. Conversely, when the COMBO interface receives an optical signal generated by the opposite-end interface, no LOS signal is generated.
Fiber, in the present invention, Fiber is used to indicate the port type of COMBO interface, i.e. optical mode, when the type of media in which the COMBO interface is effective is optical media. Specifically, when the port type of the COMBO interface is configured as Fiber, the optical port of the COMBO interface is in an operating state, and the electrical port is disabled.

In addition, before step 101, the network device is further required to set the operation mode of the COMBO interface through a command or an initialization setting, where the operation mode includes a mandatory mode and an adaptive mode. Referring to a schematic diagram of setting a working mode of a COMBO interface shown in fig. 2, specifically, if the working mode of the COMBO interface is set to be a mandatory mode, after the COMBO interface enters the mandatory mode, if a target port type of the COMBO interface is mandatory to be Copper, regardless of a currently valid port type of the COMBO interface, a currently valid port type of the COMBO interface is switched to Copper; if the target port type is forced to be Fiber, the currently effective port type is switched to Fiber regardless of the currently effective port type.
