Function

The open command establishes the FTP connection with FTP server.

Format

open [ -a source-ip | -i { interface-type interface-number | interface-name } ] host-ip-address [ port-number ] [ vpn-instance vpn-instance-name | public-net ]

open ipv6 [ -a source-ip6 ] host-ipv6-address [ port-number ] [ vpn-instance vpn-instance-name | public-net ]

open ipv6 [ -a source-ip6 ] host-ipv6-address -oi { interface-type interface-number | interface-name } [ port-number ] [ vpn-instance vpn-instance-name | public-net ]

Parameters

Parameter	Description	Value
-a source-ip	Specifies the source IPv4 address of the local machine.	The value is in the decimal format.
-a source-ip6	Source IPV6 address.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
-i interface-name	Specifies the source interface name.	-
interface-type	Specifies the source interface type.	-
interface-number	Specifies the source interface number.	-
host-ip-address	Specifies the host IP address or the host with a specific name. To view the mapping between the IPv4 address and host name, run the display dns dynamic-host or display ip host command.	The value is a string of 1 to 255 case-sensitive characters, spaces not supported.
port-number	Specifies the FTP server port number.	Port number is an integer that ranges from 1 to 65535. By default, the port number is 21.
vpn-instance vpn-instance-name	Specifies the VPN instance name.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
vpn-instance-name	Specifies the IPv6 VPN instance name.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
public-net	Specifies the public network where the FTP server resides. If you have run the set net-manager vpn-instance command to configure the default VPN instance used for an NMS to manage devices and want to use FTP to access a public network server, you must specify this parameter.	-
ipv6 host-ipv6-address	Specifies the host IPv6 address or the host with a specific name. To view the mapping between the IPv4 address and host name, run the display dns dynamic-host or display ip host command.	The value is a string case-sensitive characters, spaces not supported.
-oi	Specifies the source interface for the IPv6 FTP client, including the type and number of the interface. The IPv6 address configured in this interface view is the source IPv6 address of the packet. If no IPv6 address is configured for the source interface, the FTP connection cannot be set up. Setting the loopback interface as the source IPv6 address is recommended.	-

Usage Guidelines

Usage Scenario

You can run the ftp command in the user view to connect the FTP client and server and enter the FTP client view. If FTP is disconnected, you can run this command to establish an FTP connection.

Prerequisites

The VPN specified by vpn-instance has been configured.

Configuration Impact

After establishing successful connection with the host, you can upload or download files.

If server monitors the FTP connection through default port, you need not specify the port number. Otherwise you must specify the port number.
