In order to provide a better understanding of the present application, those skilled in the art will now make further details of the present application with reference to the drawings and detailed description.
An upgrade method for switch firmware provided in the present application is described below by using an embodiment.
Referring to fig. 1, the flowchart of a method for upgrading switch firmware according to an embodiment of the present application is shown in fig. 1, where the method includes:
s101: and acquiring an image file corresponding to the switch firmware stored in the storage device in advance.
In this step, the storage device includes devices with portability, such as a usb disk and an SD card, and the image file corresponding to the switch firmware stored in advance is the image file corresponding to the switch firmware to be upgraded. Such as: the mirror image file corresponding to the switch firmware of the high version is stored in the U disk in advance, so that the mirror image file corresponding to the switch firmware of the low version in the switch can be replaced by the mirror image file corresponding to the switch firmware of the high version in the subsequent process.
It should be noted that, the storage device may be inserted into a switch in a uboot environment, where the switch enables a USB OHCI function to support that uboot in the switch may identify the state of the storage device and the storage device, and after identifying the storage device, the MMC driver is migrated so that uboot may initialize the storage device, that is, may operate the storage device, and under the support of the FAT file system, may read a file in the storage device (that is, an image file corresponding to the pre-stored firmware of the switch) in the FAT32 format. The uboot can also detect a flash chip to be used, so that the firmware of the switch is upgraded in a flash partition in the flash chip in a subsequent process.
Further, in the present application, the switch firmware stored in the storage device in advance may be first obtained, and then the switch firmware is packaged and compressed, so as to obtain an image file corresponding to the switch firmware. In some examples, the image file corresponding to the pre-stored switch firmware may be obtained directly from the root directory of the storage device. The image file is a file in a single form, and is convenient to transmit and download.
S102: copying the mirror image file corresponding to the switch firmware into a memory partition of the switch to obtain the mirror image file corresponding to the switch firmware stored in the memory partition.
In this step, the switch includes a memory partition in FAT32 format, and before copying the image file corresponding to the switch firmware into the memory partition of the switch, it may also be determined whether the memory partition in the switch is a memory partition in FAT32 format, and if the memory partition in the switch is a memory partition in FAT32 format, the image file corresponding to the switch firmware is copied into the memory partition of the switch.
It should be noted that, in the present application, after the image file corresponding to the switch firmware is copied to the memory partition of the switch, the image file corresponding to the switch firmware stored in the memory partition is obtained, hash calculation may also be performed on the image file corresponding to the switch firmware, so as to obtain a first hash value; and performing hash calculation on the image file corresponding to the switch firmware in the memory partition to obtain a second hash value.
Further, it may also be determined whether the first hash value and the second hash value are the same, and if the first hash value and the second hash value are the same, step S103 is executed; if the first hash value is different from the second hash value, the file is indicated to have errors in the copying process, and the updating of the switch firmware is stopped at the moment. It should also be noted that the hash value in the present application may be an md5 value.
S103: and writing the image file corresponding to the switch firmware in the memory partition into a flash partition of the switch to obtain the image file corresponding to the switch firmware written into the flash partition.
Specifically, in this step, if the first hash value is the same as the second hash value, the image file corresponding to the switch firmware in the memory partition is subjected to erasing operation, so as to obtain the image file corresponding to the switch firmware written into the flash partition. After the image file corresponding to the switch firmware written into the flash partition is obtained, hash calculation can be performed on the image file corresponding to the switch firmware in the flash partition to obtain a third hash value.
Further, whether the second hash value is the same as the third hash value can be judged, if the second hash value is the same as the third hash value, the step of replacing the image to-be-updated file corresponding to the switch firmware in the flash partition with the image file corresponding to the switch firmware in the flash partition is executed, and the step of updating the switch firmware is completed; and if the second hash value is different from the third hash value, repeatedly executing the erasing operation on the mirror image file corresponding to the switch firmware in the memory partition to obtain the mirror image file corresponding to the switch firmware in the flash partition, and judging whether the hash values are the same again, and if the number of times of the hash values is different is greater than a preset number of times threshold, indicating that the file is in error in the writing process, and stopping upgrading the switch firmware at the moment.
Such as: when the second hash value is different from the third hash value, the image file corresponding to the switch firmware in the memory partition can be rewritten to obtain the image file corresponding to the switch firmware in the flash partition, which is obtained by the current rewritten operation, and further, the image file corresponding to the switch firmware in the flash partition is subjected to hash calculation to obtain a new hash value. Judging whether the second hash value is the same as the new hash value, if so, executing the step of replacing the image file to be upgraded corresponding to the switch firmware in the flash partition with the image file corresponding to the switch firmware in the flash partition, and finishing the upgrading of the switch firmware; if the second hash value is different from the new hash value, repeating the process until the number of times that the hash values are different is greater than a preset number of times threshold value, and stopping upgrading the switch firmware.
In another implementation manner, since the first hash value and the second hash value are the same, whether the first hash value and the third hash value are the same or not can be further determined, if the first hash value and the third hash value are the same, the step of replacing the image file to be upgraded corresponding to the switch firmware in the flash partition with the image file corresponding to the switch firmware in the flash partition is performed, and the step of upgrading the switch firmware is completed; and if the first hash value is different from the third hash value, repeatedly executing the erasing operation on the mirror image file corresponding to the switch firmware in the memory partition within the preset times threshold to obtain the mirror image file corresponding to the switch firmware written into the flash partition.
S104: and replacing the image file to be upgraded corresponding to the switch firmware in the flash partition with the image file corresponding to the switch firmware in the flash partition, thereby finishing the upgrading of the switch firmware.
It can be understood that, the image file corresponding to the switch firmware in the flash partition is an image file corresponding to the switch firmware to be upgraded, and when the image file corresponding to the switch firmware to be upgraded is subjected to the copying process and the writing process and the hash value is unchanged, the image file corresponding to the switch firmware to be upgraded can be replaced by the image file corresponding to the switch firmware to be upgraded, so as to complete the upgrade of the switch firmware.
Furthermore, before the image to-be-updated file corresponding to the switch firmware in the flash partition is replaced by the image file corresponding to the switch firmware in the flash partition, the image to-be-updated file corresponding to the switch firmware in the flash partition can be copied to the storage device, so that after the update fails and the file is damaged, the image to-be-updated file corresponding to the switch firmware in the flash partition can be retransmitted to the flash partition, and normal operation of the system is ensured. It should also be noted that, after the switch firmware is upgraded, the switch can be restarted, so that the switch can operate the upgraded switch firmware.
To sum up, in this embodiment, the switch firmware to be upgraded is stored in the storage device in advance, and then the switch firmware to be upgraded in the storage device is written into the flash partition of the switch, so that the switch firmware to be upgraded in the flash partition is replaced by the switch firmware to be upgraded. Therefore, the storage device is utilized to directly upgrade the switch firmware, so that the reliability is improved, and the condition of troublesome operation is reduced.
