DELL CONFIDENTIAL – PRELIMINARY 10/21/13 - FOR PROOF ONLY
Parameters
• engineid-string —Specifies a concatenated hexadecimal character string
identifying the engine ID. Each byte in a hexadecimal character string is
two hexadecimal digits. Bytes are separated by a period or colon. If an odd
number of hexadecimal digits are entered, the system automatically
prefixes the digit 0 to the string. (Length: 5–32 characters, 9–64
hexadecimal digits)
•
default —Specifies that the engine ID is created automatically based on
the device MAC address.
Default Configuration
The engine ID is not configured.
If SNMPv3 is enabled using this command, and the default is specified, the
default engine ID is defined per standard as:
• First 4 octets: First bit = 1, the rest is IANA Enterprise number = 674.
• Fifth octet: Set to 3 to indicate the MAC address that follows.
• Last 6 octets: The device MAC address.
Command Mode
Global Configuration mode
User Guidelines
To use SNMPv3, specify an engine ID for the device. Any ID can be specified
or use a default string, which is generated using the device MAC address.
As the EngineID should be unique within an administrative domain, the
following guidelines are recommended:
• For standalone devices, use the default keyword to configure the Engine
ID.
• For stackable systems, configure an EngineID, and verify that it is unique
within the administrative domain.
Changing or removing the value of snmpEngineID deletes the SNMPv3
users database.
The SNMP EngineID cannot be all 0x0 or all 0xF or 0x000000001
