tftp client-source

Function

The tftp client-source command specifies the source IP address for the TFTP client to send packets.

The undo tftp client-source command restores the default source IP address for the TFTP client to send packets.

By default, the TFTP client source address is the IP address of the outbound interface connecting to the TFTP server, and it is displayed as 0.0.0.0.

Format

tftp client-source { -a source-ip-address | -i interface-type interface-number }

undo tftp client-source

Parameters

Parameter	Description	Value
-a source-ip-address	Specifies the source IP address of the TFTP client. You are advised to use the loopback interface IP address.	The value is in dotted decimal notation.
-i interface-type interface-number	Source interface type and ID. You are advised to use the loopback interface. The IP address configured for this interface is the source IP address for sending packets. If no IP address is configured for the source interface, the TFTP connection cannot be set up.	-

Usage Guidelines

Usage Scenario

If no source IP address is specified, the client uses the source IP address that the router specifies to send packets. The source IP address must be configured for an interface with stable performance. The loopback interface is recommended. Using the loopback interface as the source interface simplifies the ACL rule and security policy configuration. This shields the IP address differences and interface status impact, filters incoming and outgoing packets, and implements security authentication.

Prerequisites

The source interface specified using the command must exist and have an IP address configured.

Precautions

The tftp command also configures the source IP address whose priority is higher than that of the source IP address specified in the tftp client-source command. If you specify source addresses in the tftp client-source and tftp commands, the source IP address specified in the tftp command is used for data communication. The source address specified in the tftp client-source command applies to all TFTP connections. The source address specified in the tftp command applies only to the current TFTP connection.
You can query the source IP address or source interface IP address specified in the TFTP connection on the TFTP server.

Example

# Set the source IP address of the TFTP client to 10.1.1.1.
