Background
In the trunking forwarding system, the trunking frame data planes are fully connected by using standard optical fibers through a Multi-Switching Fabric Unit (MSFU), which is a Multi-frame Switching Fabric Unit, in order to ensure correct forwarding of data traffic between frames (line card frames). One or more screens are arranged in one wire clamp frame, and data channel connection between the cluster frames needs to ensure that two interconnected meshes (namely chips on the screens) are in different working modes.

Detailed Description
In order to make the technical solutions in the embodiments of the present invention better understood and make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
Referring to fig. 2, a flow chart of a port state control method according to an embodiment of the present invention is shown, and as shown in fig. 2, the port state control method may include the following steps:
it should be noted that the execution subject of steps 201 to 203 may be any network board (referred to as a target network board herein) in the multi-chassis cluster routing device.
In the embodiment of the present invention, when the same optical fiber is inserted into any optical interface and another optical interface on the target screen, the state of the port on the mesh corresponding to the optical interface changes from a Down (non-operating) state to an UP (operating) state, and at this time, the mesh reports a hardware interrupt signal.
It should be noted that, in the embodiment of the present invention, unless otherwise specified, the hardware interrupt signal mentioned herein refers to a hardware interrupt signal triggered when the state of the port on the mesh changes from the Down state to the UP state, and the following description of the embodiment of the present invention is not repeated.
When the target network board detects a hardware interrupt signal reported by the mesh, the target network board may read the port state register of the mesh and obtain a port (referred to as a target port herein) with a port state of UP from the port state register.
In the embodiment of the invention, after the target screen plate acquires the target port in the UP state on the mesh, the target screen plate can acquire the port information of the target port and the port information of an opposite port connected with the target port for any target port; the port information includes an operation mode of the mesh to which the port belongs (e.g., Multi _ FE13 or Multi _ FE 2).
And 203, when the working mode of the mesh to which the target port belongs is the same as that of the mesh to which the opposite end port belongs, enabling the target port or the opposite end port according to a preset strategy.
In the embodiment of the present invention, after the target mesh board obtains the port information of the target port and the opposite port, it may be determined whether the working mode of the mesh to which the target port belongs and the working mode of the mesh to which the opposite port belongs are the same.
If the working mode of the mesh to which the target port belongs is the same as that of the mesh to which the opposite port belongs, the target mesh board can determine that an optical interface connection error occurs, and at the moment, the target mesh board can enable the target port or the opposite port according to a preset strategy.
For example, the target network board may issue a disable command, such as a shut down command, to the target port or the peer port through software to disable the target port or the peer port.
When the port is disabled, the port does not receive or send signals any more, and the port is not enabled again in response to plugging and unplugging of the optical fiber.
It should be noted that, in the embodiment of the present invention, if the working mode of the mesh to which the target port belongs is different from the working mode of the mesh to which the opposite port belongs, it is determined that the optical interface connection is normal, and the optical interface connection may be processed according to the existing flow, which is not described in detail in this embodiment of the present invention.
As can be seen, in the method flow shown in fig. 2, by disabling one of the ports corresponding to the optical interface with the connection error, the influence of the connection error of the optical interface on the service operation is shielded, the situations of routing topology confusion and flow cutoff are avoided, and the normal forwarding of the data flow is ensured.
In one embodiment of the present invention, the port information may further include a device number of a mesh to which the port belongs;
correspondingly, the disabling the target port or the opposite port according to the preset policy may include:
when the equipment number of the mesh to which the target port belongs is different from that of the mesh to which the opposite port belongs, the port with the smaller equipment number of the mesh in the target port and the opposite port is disabled;
or the like, or, alternatively,
and when the equipment number of the mesh sheet of the target port is different from that of the mesh sheet of the opposite port, disabling the port with the larger equipment number of the mesh sheet of the target port and the opposite port.
In this embodiment, a port with a smaller Module Identity (MODID) of the mesh to which the disable belongs is taken as an example.
In this embodiment, when the target mesh board determines that the working mode of the mesh to which the target port belongs is the same as the working mode of the mesh to which the opposite port belongs, the target mesh board may compare the MODID of the mesh to which the target port belongs and the MODID of the mesh to which the opposite port belongs.
When the MODID of the mesh to which the target port belongs is larger than the MODID of the mesh to which the opposite port belongs, the target mesh board can disable the opposite port;
when the MODID of the mesh to which the target port belongs is smaller than the MODID of the mesh to which the opposite port belongs, the target mesh may disable the target port.
Further, in an implementation manner of this embodiment, the port information may further include a port ID;
correspondingly, the disabling the target port or the opposite port according to the preset policy may further include:
when the equipment number of the mesh sheet to which the target port belongs is the same as that of the mesh sheet to which the opposite port belongs, the port with smaller port ID in the target port and the opposite port is disabled;
or the like, or, alternatively,
and when the equipment number of the mesh sheet to which the target port belongs is the same as that of the mesh sheet to which the opposite port belongs, disabling the port with the larger port ID in the target port and the opposite port.
In this embodiment, a port with a smaller port ID is disabled as an example.
In this embodiment, when the target mesh board determines that the working mode of the mesh to which the target port belongs is the same as the working mode of the mesh to which the opposite port belongs, and the device number of the mesh to which the target port belongs is the same as the device number of the mesh to which the opposite port belongs, the target mesh board may compare the port ID of the target port with the port ID of the opposite port.
If the port ID of the target port is greater than the port ID of the opposite port, the target mesh board can enable the opposite port.
If the port ID of the destination port is smaller than the port ID of the opposite port, the destination network board can disable the destination port.
It should be appreciated that the policy for disabling the target port or the peer port described in the foregoing method embodiments is merely a specific example of the implementation manner of selecting the disabled port in the embodiment of the present invention, and does not belong to the limitation of the protection scope of the present invention.
In addition, in the embodiment of the present invention, when the target mesh board determines that the port that needs to be disabled is the opposite port, if the opposite port is not the port on the mesh board, the target mesh board may not perform the disabling process, but perform the disabling process on the port by the mesh board to which the opposite port belongs according to the method described in the above method flow, which will not be described again in the following.
Further, in the embodiment of the present invention, in consideration that the port cannot be automatically restored after being disabled, it is necessary to provide a mechanism for restoring the port to be enabled, so as to avoid wasting the port resource of the device.
In an embodiment of the present invention, after the disabling the target port or the peer port according to the preset policy, the method may further include:
setting a designated mark for an optical interface corresponding to the disabled port;
correspondingly, the port state control method provided by the embodiment of the invention may further include:
polling each optical interface on the screen regularly;
and for any optical interface provided with the specified mark, when the los signal exists in the optical interface, restoring the port enabling corresponding to the optical interface, and deleting the specified mark set for the optical interface.
In this embodiment, a flag (referred to as a designated flag herein) may be added to indicate that the port corresponding to the optical interface is in the disabled state, and after the target board disables the port, the designated flag may be set for the optical interface corresponding to the disabled port.
Accordingly, in this embodiment, the target screen may time-cycle each optical interface on the screen to determine whether there is an optical interface provided with the above-mentioned designation mark.
When the target network board determines that the optical interface provided with the specified mark exists, the target network board can judge whether a los (light loss) signal exists in any optical interface provided with the specified mark, and when the optical interface has the light loss los signal, namely when an optical fiber pulling event occurs in the optical interface or/and the optical interface corresponding to the optical interface, the target network board can recover the port enabling corresponding to the optical interface and delete the specified mark set by the optical interface.
It should be noted that, in the embodiment of the present invention, the specified flag may be a field whose value is a first flag value, and accordingly, when the specified flag set by the optical interface is deleted, the value of the field may be set to a second flag value.
In addition, in the embodiment of the present invention, for any optical interface provided with the designated mark, when the optical interface does not have a los signal, the target screen board may continue to poll other optical interfaces, and the specific implementation thereof is not described herein again.
Therefore, in the embodiment of the invention, the target network board can recover the corresponding port enabling after the optical fiber with the wrong connection is pulled out, and further, the port can be normally used for receiving and sending the flow, thereby avoiding the waste of equipment port resources.
Further, in one embodiment of the present invention, when the target mesh board determines that the working mode of the mesh to which the target port belongs is the same as the working mode of the mesh to which the opposite port belongs, an alarm message may be generated, where the alarm message is used to prompt that an optical interface connection error exists, and the alarm message may carry an optical interface index of an optical interface where the optical interface connection error exists.
