If you tried to access an FTP server but failed to pass the authentication, you can use this command to try again before the connection to the FTP server expires.

After you log in to an FTP server, you can initiate an FTP authentication to change to a new account. By changing to a new account, you can get a different privilege without re-establishing the FTP connection.

Make sure the specified username and password have been configured on the FTP server. If the username or password is not configured, this command fails and the FTP connection is closed.

Examples

# After logging in to the FTP server, use username ftp and password 123456 to log in again to the FTP server.

·     Method 1:

ftp> user ftp 123456

331 Password required for ftp.

230 User logged in.

·     Method 2:

ftp> user ftp

331 Password required for ftp.

Parameters

tftp-server: Specifies the IPv4 address or host name of a TFTP server. The host name can be a case-insensitive string of 1 to 253 characters and can contain only letters, digits, hyphens (-), underscores (_), and dots (.).

get: Downloads a file and writes the file directly to the destination folder. If the destination folder already has a file with the same name, the system deletes the existing file before starting the download operation. The existing file is permanently deleted even if the download operation fails.

put: Uploads a file.

sget: Downloads a file and saves the file to memory before writing it to the destination folder. The system starts to write the file to the destination folder only after the file is downloaded and saved to memory successfully. If the destination folder already has a file with the same name, the system overwrites the existing file. If the download or save-to-memory operation fails, the existing file in the destination folder is not overwritten.

source-filename: Specifies the source file name, a case-insensitive string of 1 to 1 to 255 characters.

destination-filename: Specifies the destination file name, a case-insensitive string of 1 to 255 characters. If this argument is not specified, the file uses the source file name.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the TFTP server belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters. If the TFTP server belongs to the public network, do not specify this option.

dscp dscp-value: Specifies the DSCP value for IPv4 to use for outgoing TFTP packets to indicate the packet transmission priority. The value range is 0 to 63. The default is 0.

source { interface interface-type interface-number | ip source-ip-address }: Specifies the source address for outgoing TFTP packets. If you do not specify this option, the device uses the primary IPv4 address of the output interface for the route to the TFTP server as the source address.

·     interface interface-type interface-number: Specifies an interface by its type and number. The device will use the interface's primary IPv4 address as the source IPv4 address. For successful TFTP packet transmission, make sure the interface is up and has the primary IPv4 address configured.

·     ip source-ip-address: Specifies an IPv4 address. For successful TFTP packet transmission, make sure this address is the IPv4 address of an interface in up state on the device.

Usage guidelines

The source address specified with the tftp command takes precedence over the source address specified with the tftp client source command.

The source address specified with the tftp client source command applies to all TFTP connections. The source address specified with the tftp command applies only to the current TFTP connection.
