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
1 Run the esxcli system snmp set command with the --targets option:
esxcli system snmp set --targets target_address@port/community
Here, target_address is the address of the target system, port is the port number to send the
notifications to, and community is the community name.
Each time you specify a target with this command, the settings you specify overwrite all previously
specified settings. To specify multiple targets, separate them with a comma.
For example, run the following command for configuring the targets 192.0.2.1@163/westnoc and
2001:db8::1@163/eastnoc:
esxcli system snmp set --targets 192.0.2.1@163/westnoc,2001:db8::1@163/eastnoc
2 (Optional) If the ESXi SNMP agent is not enabled, run the following command:
esxcli system snmp set --enable true
3 (Optional) Send a test trap to verify that the agent is configured correctly by running the esxcli
system snmp test command.
The agent sends a warmStart trap to the configured target.
Configure ESXi for SNMP v3
When you configure the ESXi SNMP agent for SNMPv3, the agent supports sending informs and traps.
SNMPv3 also provides stronger security than SNMPv1 or SNMPv2c, including key authentication and
encryption.
Inform is a notification that the sender resends up to three times or until the receiver acknowledges the
notification.
Procedure
1 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.
