local-source-interface

Function

The local-source-interface command sets a source interface and a source port number when a protocol is used for data sending.

The undo local-source-interface command deletes the source interface and source port number configured when a protocol is used for data sending.

By default, the source interface and source port are not configured.

Format

local-source-interface { if-name | if-type if-number } [ port port-value ]

undo local-source-interface { if-name | if-type if-number } [ port port-value ]

Parameters

Parameter	Description	Value
if-name	Interface name.	The value is a string of 1 to 63 characters without spaces.
if-type	Interface type.	-
if-number	Interface number.	The value is a string of 1 to 63 characters without spaces.
port port-value	Specifies the IPv4 source port number in protocol-based packet sending mode.	The value is an integer ranging from 1 to 65535.

Usage Guidelines

Usage Scenario

To statically subscribe to the data sampled, you need to run the local-source-interface command to configure a source interface and a source port number (a source port number is required only when UDP is used for data sending) in the subscription view for data sending. This ensures that devices can communicate with the collector.Only one combination that consists of a source interface and a source port number can be configured for a subscription. After the configuration is complete:- The UDP message header sent along the UDP channel contains the configured source interface and source port number.- The gRPC message header sent along the gRPC channel contains the configured source interface.

Precautions

Only one of the local-source-interface and local-source-address commands can be configured in the same subscription view.

Example

# Set the source interface to LoopBack0 and the source port number to 2345 for UDP packets.
