Release Information

Statement introduced before JUNOS Release 7.4.

Description

The local engine ID is defined as the administratively unique identifier of an SNMPv3 engine, and is used for identification, not for addressing. There are two parts of an engine ID: prefix and suffix. The prefix is formatted according to the specifications defined in RFC 3411, An Architecture for Describing Simple Network Management Protocol (SNMP) Management Frameworks. You can configure the suffix here.

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

For the engine ID, we recommend using the MAC address of fxp0.

Options

local engine-id-suffix—Explicit setting for the engine ID suffix.
use-default-ip-address—The engine ID suffix is generated from the default IP address.
use-mac-address—The SNMP engine identifier is generated from the MAC address of the management interface on the routing platform.

Usage Guidelines

See Configuring the Local Engine ID.
