Managing System Files
This section describes how to upgrade the switch operating software or
configuration files, and set the system start-up files.
Copying Files via FTP/
SFTP/TFTP or HTTP
Use the System > File (Copy) page to upload/download firmware or configuration
settings using FTP, SFTP, TFTP or HTTP. By backing up a file to a FTP/SFTP/TFTP
server or management station, that file can later be downloaded to the switch to
restore operation. Specify the method of file transfer, along with the file type and
file names as required.
You can also set the switch to use new firmware or configuration settings without
overwriting the current version. Just download the file using a different name from
the current version, and then set the new file as the startup file.
Command Usage
◆
When logging into an FTP/SFTP server, the interface prompts for a user name
and password configured on the remote server. Note that “Anonymous” is set
as the default user name.
◆
Secure Shell FTP (SFTP) provides a method of transferring files between two
network devices over an SSH2-secured connection. SFTP functions similar to
Secure Copy (SCP), using SSH for user authentication and data encryption.
Although the underlying premises of SFTP are similar to SCP, it requires some
additional steps to verify the protocol versions and perform security checks.
SFTP connection setup includes verification of the DSS signature, creation of
session keys, creation of client-server and server-client ciphers, SSH key
exchange, and user authentication. An SFTP channel is then opened, the SFTP
protocol version compatibility verified, and SFTP finally initialized.
◆
The reset command will not be accepted during copy operations to flash
memory.
