The scp client-source command specifies the source IP address for the SCP client to send packets.
The undo scp client-source command cancels the source IP address for the SCP client to send packets.
By default, no source IP address is configured on the SCP client.
scp client-source { -a source-ip-address | -i interface-type interface-number }
undo scp client-source
| Parameter | Description | Value |
|---|---|---|
| -a source-ip-address | Specifies the source IP address of the SCP client. You are advised to use the loopback interface IP address. |
- |
| -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 SCP connection cannot be set up. |

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 scp command also configures the source IP address whose priority is higher than that of the source IP address specified in the scp client-source command. If you specify source addresses in the scp client-source and scp commands, the source IP address specified in the scp command is used for data communication. The source address specified in the scp client-source command applies to all SCP connections. The source address specified in the scp command applies only to the current SCP connection.
