Parameters
tftp-server: Specifies the IPv6 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 (.).
-i interface-type interface-number: Specifies an output interface by its type and number. This option can be used only when the TFTP server address is a link local address and the specified output interface has a link local address. For information about link local addresses, see Layer 3—IP Services Configuration Guide.
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 using 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 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 IPv6 to use in 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 | ipv6 source-ipv6-address }: Specifies the source address for outgoing TFTP packets. If you do not specify this option, the device selects a source IPv6 address as defined in RFC 3484.
interface interface-type interface-number: Specifies an interface by its type and number. The device will use the interface's IPv6 address as the source IPv6 address. For successful TFTP packet transmission, make sure the interface is up and is configured with an IPv6 address.
ipv6 source-ipv6-address: Specifies an IPv6 address. For successful TFTP packet transmission, make sure this address is the IPv6 address of an interface in up state on the device.
Usage guidelines
The source address specified with the tftp ipv6 command takes precedence over the source address specified with the tftp client ipv6 source command.
The source address specified with the tftp client ipv6 source command applies to all TFTP connections. The source address specified with the tftp ipv6 command applies only to the current TFTP connection.
Examples
# Download the new.bin file from the TFTP server at 2001::1 and save it as new.bin.
<Sysname> tftp ipv6 2001::1 get new.bin new.bin
