Release Information

Statement introduced in Junos OS Release 11.1 for the QFX Series.

Description

Define a unique identifier for an SNMPv3 engine by configuring the suffix of the engine ID. The engine ID is used for identification only and not for addressing. There are two parts of an engine ID: the prefix and the suffix. The prefix is formatted according to the specifications defined in RFC 3411, An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks and cannot be configured. The suffix is configured here.

Note: SNMPv3 authentication and encryption keys are generated based on the associated user passwords and the engine ID. If you configure or change the engine ID, you must commit the user passwords and new engine ID before you configure SNMPv3 users, or the authentication will fail.

By default, the engine ID suffix is configured with the MAC address of the management interface (the use-mac-address option) on the QFX Series. You can override this configuration by using the local engine-id-suffix or use-default-ip-address option.
