The snmp-agent local-engineid command sets an engine ID for the local SNMP agent.
The undo snmp-agent local-engineid command restores the engine ID of the local SNMP agent to the default value.
By default, the device uses an internal algorithm to automatically generate an engine ID for a device. The engine ID consists of the enterprise number and the device information.
| Parameter | Description | Value |

Usage Scenario
You can run the snmp-agent local-engineid command to set an engine ID for the local SNMP agent for identification.
The SNMP engine ID uniquely identifies an SNMP agent in a management domain. The SNMP engine ID is an important component of the SNMP agent. It schedules and processes SNMP messages, and implements security authentication and access control. You can use the display snmp-agent local-engineid command to check the engine ID of the local SNMP entity.
When setting an engine ID, you need to comply with the following rules:
The length of the octet strings varies. The first four octets are set to the binary equivalent of the agent, which is SNMP management private enterprise number and is assigned by the Internet Assigned Numbers Authority (IANA). The engine ID of Huawei devices is 2011 in decimal notation. The first digit is in binary format, and has a fixed value 1. Therefore, the engine ID in hexadecimal format is 800007DB.
The device information can be configured manually. It is recommended that the IP address or MAC address of the device be used as the device information to uniquely identify the device.
