Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following describes an embodiment of a method for processing redundancy of a mirror port of a fabric switch in detail based on the present invention. As shown in fig. 1, which is a schematic flowchart of a method for processing a mirror port redundancy of an optical fiber switch according to an embodiment of the present invention, a specific implementation process includes the following steps:
step 101: determining a corresponding primary mirror image port and a corresponding standby mirror image port based on configuration data of a corresponding logic register of the optical fiber switch; wherein the use priority of the primary image port is higher than that of the standby image port.
In the embodiment of the present invention, when the configuration data of the logical register corresponding to the Fiber Channel Switch (FC) is 0, it is determined that the working mode of the corresponding port is the primary mirroring port; and when the configuration data of the logic register corresponding to the optical fiber switch is 1, determining that the working mode of the corresponding port is a standby mirror image port. The optical fiber switch is high-speed network transmission relay equipment and adopts an optical fiber cable as a transmission medium. The backup of the data forwarded by the original mirror image port can be realized through the redundant processing of the mirror image port (port Mirroring, data exchange port), so as to achieve the purpose of enhancing the stability and the security of the monitoring data.
In the implementation process, monitoring data of one or more ports (VLANs) of the fabric switch are mirrored onto one or more preset mirror ports, which is called "port mirroring", and the corresponding ports are mirror ports. The image port may be a primary image port or a backup image port.
Step 102: forwarding a monitoring data frame based on the main mirror image port, synchronously caching the monitoring data frame forwarded by the main mirror image port based on a preset frame backup module, monitoring the link state of the main mirror image port in real time, judging whether the main mirror image port forwards the monitoring data frame currently when the link state of the main mirror image port is monitored to be abnormal, if the main mirror image port forwards the monitoring data frame and has the monitoring data frame which is not forwarded completely, continuing caching the monitoring data frame which is not forwarded completely by the main mirror image port into the frame backup module, and enabling the request to be retransmitted.
The frame backup module is implemented based on a Block random access memory (Block RAM) configuration, and is configured to synchronously store, in real time, a monitoring data frame that is sent by the active/standby switching logic module and is not forwarded when the main mirror port is abnormal or a monitoring data frame that is sent by the standby mirror port is abnormal. The specific implementation is shown in fig. 3.
Step 103: and judging whether the link state of the standby mirror image port is abnormal or not, if not, reading the monitoring data frame which is not forwarded and completed by the main mirror image port from the frame backup module based on the retransmission request, forwarding the monitoring data frame which is not forwarded and completed by the main mirror image port to a target port through the standby mirror image port, and forwarding a subsequent monitoring data frame based on the standby mirror image port.
In a specific implementation process, after step 102 is executed, it is first determined whether a link state of the standby mirror port is abnormal, if not, it is further determined whether the retransmission request exists, and if the retransmission request exists, the monitoring data frame that is not completely forwarded by the primary mirror port is read from the frame backup module, and the monitoring data frame that is not completely forwarded by the primary mirror port is forwarded to a target port through the standby mirror port, so that a subsequent monitoring data frame is forwarded based on the standby mirror port.
In addition, after the monitoring data frame is forwarded based on the standby mirror image port, the monitoring data frame forwarded by the standby mirror image port is synchronously cached based on the frame backup module, the link state of the standby mirror image port is monitored in real time, when the monitored link state of the standby mirror image port is abnormal, whether the monitoring data frame is forwarded by the standby mirror image port is judged, if the monitoring data frame is forwarded by the standby mirror image port and the monitoring data frame which is not forwarded is existed, the monitoring data frame which is not forwarded by the standby mirror image port is continuously cached and backed up to the frame backup module, a retransmission request is enabled, and the monitoring data frame which is not forwarded by the standby mirror image port is retransmitted to a target port.
It should be noted that, in the embodiment of the present invention, two optical fiber ports need to be configured as a primary mirror image port and a standby mirror image port in advance, and the primary mirror image port is preferentially used as a currently used mirror image port, and when a link failure occurs in the primary mirror image port and a link of the standby mirror image port is normal, the primary mirror image port may be switched to the standby port based on a preset primary/standby switching logic module to serve as the currently used mirror image port; if the standby mirror image port is switched to the standby mirror image port currently, when the standby mirror image port link fails and the main mirror image port link is normal, the standby mirror image port link can be switched to the main mirror image port based on a preset standby switching logic module to be the currently used mirror image port; in the process of switching the main mirror image port and the standby mirror image port, if the monitoring data frame is not forwarded completely before switching, the monitoring data frame can be retransmitted based on the monitoring data frame retransmission mechanism preset by the invention after switching, so that the forwarded data is ensured not to be lost.
