RouterOS使用fetch给华为交换机上传补丁升级

需要将升级补丁S5731-H_V200R022SPH180.pat放到RouterOS file文件路径下（通过winbox上传更方便），确保RouterOS有足够的存储空间，如果RouterOS/RB设备的ROM存储在128M以下，不建议直接写入存储，需额外挂载U盘或者其他存储介质存储补丁和固件文件。

华为交换机的管理IP假设是192.168.0.254，需要上传S5731-H_V200R022SPH180.pat补丁，进入tool，使用fetch命令上传，文件存放路径是在file的根路径下，因此RouterOS配置如下：

[admin@ros] /tool> fetch address=192.168.0.254 src-path=S5731-H_V200R022SPH180.pat user=ftpuser password=Huawei@123 mode=ftp dst-path=S5731-H_V200R022SPH180.pat upload=yes

华为交换机dir命令查看补丁是否上传成功

运行补丁命令，通常补丁不需要重启交换机，直接生效

<HUAWEI>patch load s5731-h_v200r022sph180.pat all run
Info: The patch is being loaded. Please wait for a moment.

补丁升级比较简单无需重启交换机，对于远程升级版本固件需要重启交换机，RouterOS也是可以这样操作，但风险需要你自己评估。
