方法一：

准备工作：
1.搭建ftp server或sftp server
2.光交能正常ping通ftp server
日志方法如下：
SNS2224:root> supportsave
This command collects RASLOG, TRACE, supportShow, core file, FFDC data
and then transfer them to a FTP/SCP/SFTP server or a USB device.
This operation can take several minutes.
NOTE: supportSave will transfer existing trace dump file first, then
automatically generate and transfer latest one. There will be two trace dump
files transferred after this command.
OK to proceed? (yes, y, no, n): [no] y
Host IP or Host Name: x.x.x.x ftp server IP
User Name:xxx fpt server用户名
Password: ftp用户密码
Protocol (ftp | scp | sftp): sftp 选择传输协议
Remote Directory:xxx ftp server目录名称（保存目录）
