The snmp-agent protocol source-interface command specifies a source interface for SNMP to receive and respond to requests from an NMS.
The undo snmp-agent protocol source-interface command restores the default configuration.
The snmp-agent proxy protocol source-interface command specifies a source interface for the SNMP proxy to receive and respond to requests from the CCU.
The undo snmp-agent proxy protocol source-interface command restores the default configuration.
The snmp-agent protocol physic-isolate source-interface command specifies an isolate source interface for SNMP to receive and respond to requests from an NMS.
The undo snmp-agent protocol physic-isolate source-interface command restores the default configuration.
The snmp-agent proxy protocol physic-isolate source-interface command specifies an isolate source interface for the SNMP proxy to receive and respond to requests from the CCU.
The undo snmp-agent proxy protocol physic-isolate source-interface command restores the default configuration.
By default, no source interface is specified for SNMP to receive and respond to requests from an NMS. The function that allows all interfaces on the device to be used by SNMP to receive and respond to requests from an NMS is not enabled. No source interface is specified for the SNMP proxy to receive and respond to requests from the CCU. The function that allows all interfaces on the device to be used by the SNMP proxy to receive and respond to requests from the CCU is not enabled.

| Parameter | Description | Value |
|---|---|---|
| protocol-interface-type |
Specifies the type of a source interface. |
- |
| protocol-interface-number |
Specifies the number of a source interface. |
The value is a string of 1 to 63 case-sensitive characters, spaces not supported. |
| protocol-interface-name |
Specifies the name of a source interface. |
The value is a string of 1 to 63 case-sensitive characters, spaces not supported. |
| source-ip ipv4-address |
Specifies an IPv4 source address for SNMP. |
The value is in the decimal format. |
Usage Scenario
To specify a source interface for SNMP to receive and respond to requests from an NMS, run the snmp-agent protocol source-interface command.
To specify an isolate source interface and source IP for SNMP to receive and respond to requests from an NMS, run the snmp-agent protocol physic-isolate source-interface source-ip command.
To allow data to be managed in a unified manner, you can specify the source interface for the SNMP proxy to receive and respond to requests from the CCU or configure the function that allows all interfaces on the device to be used by the SNMP proxy to receive and respond to requests from the CCU.
Prerequisites
When the specified source interface is a non-isolated interface, the command takes effect if the interface exists and is configured with a valid IP address. If the interface does not exist, the command fails to be configured.
If the specified non-isolated source interface exists but is not configured with a valid IP address, the command does not take effect. After a valid IP address is configured for the interface, this command automatically takes effect.
When the specified source interface is an isolated interface, the command takes effect if the interface exists. If the specified interface does not exist, the command fails to be configured.
Precautions
The snmp-agent protocol source-interface command does not support interface association. That is, after the configured source interface is deleted or the IP address of the interface is deleted or changed, the NMS cannot communicate with the device through the original IP address of the interface.
After SNMP is bound to source interfaces, SNMP uses only these interfaces on the device to receive and respond to requests from the NMS, and the NMS communicates with the device only through the IP addresses of these interfaces. After a source interface's IP address is changed, this IP address cannot be used for the communication between the NMS and device any more.
The snmp-agent protocol source-interface command can be used to specify a maximum of 20 source interfaces for SNMP to receive and respond to requests from an NMS.
The snmp-agent proxy protocol source-interface command can be used to specify a maximum of 20 source interfaces for the SNMP proxy to receive and respond to requests from the CCU.
