Run the undo snmp-agent local-engineid command on the device to restore the default engine ID of the local SNMP entity and re-configure SNMP parameters.
If you want to set a local engine ID by yourself, comply with the following principles:
The first four bytes in hexadecimal notation are the enterprise's private engine ID allocated by Internet Assigned Numbers Authority (IANA). The engine ID of Huawei devices is 2011 in decimal notation. The first binary digit has a fixed value 1. Therefore, the engine ID in hexadecimal format is 800007DB.
The device information is configured manually. You are advised to use the IP address or MAC address of the device as device information to uniquely identify the device.
