Feature Configuration
The Engine ID is used by SNMPv3 entities to uniquely identify them. An SNMP agent is considered
an authoritative SNMP engine. This means that the agent responds to incoming messages (Get,
GetNext, GetBulk, Set) and sends trap messages to a manager. The agent's local information is
encapsulated in fields in the message.
Each SNMP agent maintains local information that is used in SNMPv3 message exchanges. The
default SNMP Engine ID is composed of the enterprise number and the default MAC address. This
engine ID must be unique for the administrative domain, so that no two devices in a network have
the same engine ID.
Local information is stored in four MIB variables that are read-only (snmpEngineId,
snmpEngineBoots, snmpEngineTime, and snmpEngineMaxMessageSize).
Caution
—When the engine ID is changed, all configured users and groups are erased.
