2 Configure SNMP Authentication and Privacy Protocols
SNMPv3 optionally supports authentication and privacy protocols.
3 Configure SNMP Users
You can configure up to 5 users who can access SNMP v3 information. User names must be no
more than 32 characters long.
4 Configure SNMP v3 Targets
Configure SNMP v3 targets to allow the ESXi SNMP agent to send SNMP v3 traps and informs.
Configure the SNMP Engine ID
Every SNMP v3 agent has an engine ID which serves as a unique identifier for the agent. The engine ID
is used with a hashing function to generate keys for authentication and encryption of SNMP v3
messages.
If you do not specify an engine ID, when you enable the SNMP agent, an engine ID is automatically
generated.
If you run ESXCLI commands through vCLI, you must supply connection options that specify the target
host and login credentials. If you use ESXCLI commands directly on a host using the ESXi Shell, you can
use the commands as given without specifying connection options. For more information on connection
options see vSphere Command-Line Interface Concepts and Examples.
Prerequisites
Configure the ESXi SNMP agent by using the ESXCLI commands. See Getting Started with vSphere
Command-Line Interfaces for more information on how to use ESXCLI.
Procedure
u
Run the esxcli system snmp set command with the --engineid option to configure the SNMP
engine ID.
For example, run the following command:
esxcli system snmp set --engineid id
Here, id is the engine ID and it must be a hexadecimal string between 5 and 32 characters long.
Configure SNMP Authentication and Privacy Protocols
SNMPv3 optionally supports authentication and privacy protocols.
Authentication is used to ensure the identity of users. Privacy allows for encryption of SNMP v3
messages to ensure confidentiality of data. These protocols provide a higher level of security than is
available in SNMPv1 and SNMPv2c, which use community strings for security.
Both authentication and privacy are optional. However, you must enable authentication to enable privacy.
The SNMPv3 authentication and privacy protocols are licensed vSphere features and might not be
available in some vSphere editions.
