Parameters
None
Description
Use the passive command to set the data transmission mode to passive.
Use the undo passive command to set the data transmission mode to active.
The default transmission mode is passive.
Data transmission modes fall into the passive mode and the active mode. In active mode, the FTP server initiates a data connection request. In passive mode, the FTP client initiates a data connection request. This command is mainly used in conjunction with a firewall to restrict FTP session establishment between private and public network users.

Description
Use the put command to upload a file on the client to the remote FTP server.
By default, if no name is assigned to the file to be saved on the FTP server, the name of the source file is used.
After a file is uploaded, it will be saved under the user’s authorized directory, which can be set with the authorization-attribute command on the remote server.
Examples
# Upload source file cc.txt to the remote FTP server and save it as dd.txt.
[ftp] put cc.txt dd.txt

2: System level
Parameters
interface interface-type interface-number: Specifies the source interface for establishing TFTP connections. The primary IP address of the source interface is used as the source IP address of packets sent to a TFTP server. If the source interface has no primary IP address specified, no TFTP connection can be established.
ip source-ip-address: Specifies the source IP address of packets sent to a TFTP server, which is one of the IP addresses configured on the device.

Use the tftp client source command to specify the source IP address of packets sent to a TFTP server.
Use the undo tftp client source command to restore the default.
By default, the source IP address is the IP address of the output interface of the route to the server is used as the source IP address..
If you use the tftp client source command to first configure a source interface and then a source IP address, the source IP address overwrites the source interface, and vice versa.
If you first use the tftp client source command to specify a source IP address and then use the tftp command to specify another source IP address, the latter is used.
The source IP address specified with the tftp client source command applies to all TFTP connections while the one specified with the tftp command applies to the current TFTP connection only.
Related commands: display tftp client configuration.
Examples
# Specify the source IP address of packets sent a TFTP server as 2.2.2.2.
