SNMP Commands
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 — MAC address of the device.
Command Mode
Global Configuration mode.
User Guidelines
•
To use SNMPv3, you have to specify an engine ID for the device. You can specify your own ID or use a
default string that is generated using the MAC address of the device.
•
If the SNMPv3 engine ID is deleted or the configuration file is erased, SNMPv3 cannot be used. By
default, SNMPv1/v2 are enabled on the device. SNMPv3 is enabled only by defining the Local Engine
ID.
•
If you want to specify your own ID, you do not have to specify the entire 32-character engine ID if it
contains trailing zeros. Specify only the portion of the engine ID up to the point where just zeros
remain in the value. For example, to configure an engine ID of 123400000000000000000000, you can
specify snmp-server engineID local 1234.
•
Since the engine ID should be unique within an administrative domain, the following is
recommended:
–
For a standalone device, use the default keyword to configure the engine ID.
–
For a stackable system, configure the engine ID to be used for the entire stack, and verify that the
stack engine ID is unique throughout the entire management network.
•
Changing the value of the engine ID has the following important side-effect. A user's password
(entered on the command line) is converted to an MD5 or SHA security digest. This digest is based on
both the password and the local engine ID. The user’s command line password is then destroyed, as
required by RFC 2274. As a result, the security digests of SNMPv3 users become invalid if the local
value of the engine ID change, and the users will have to be reconfigured.
•
You cannot specify an engine ID that consists of all 0x0, all 0xF or 0x000000001.
•
The
show running-config
Privileged EXEC mode command does not display the SNMP engine ID
configuration. To see the SNMP engine ID configuration, enter the
snmp-server engineID local
Global Configuration mode command.
