Parameter Description
userid The user name.
authhash The authentication hash value.
privhash The privacy hash value.
security The level of security enabled for that user, which can be auth (for authentication only), priv (for
authentication and privacy), or none (for no authentication or privacy).
For example, run the following command to configure user1 for access with authentication and privacy:
esxcli system snmp set --users user1/08248c6eb8b333e75a29ca0af06b224faa7d22d6/
232ba5cbe8c55b8f979455d3c9ca8b48812adb97/priv
You must run the following command to configure user2 for access with no authentication or privacy:
esxcli system snmp set --users user2/-/-/none
3 (Optional) Test the user configuration by running the following command:
esxcli system snmp test --users username --auth-hash secret1 --priv-hash secret2
If the configuration is correct, this command returns the following message: "User username validated
correctly using engine id and security level: protocols". Here, protocols indicates the security protocols
configured.
Configure SNMP v3 Targets
Configure SNMP v3 targets to allow the ESXi SNMP agent to send SNMP v3 traps and informs.
SNMP v3 allows for sending both traps and informs. An inform is a message that the sender will resend a
maximum of three times, waiting 5 seconds between each attempt, unless the message is acknowledged by
the receiver.
You can configure a maximum of three SNMP v3 targets, in addition to a maximum of three SNMP v1/v2c
targets.
To configure a target, you must specify a hostname or IP address of the system that will receive the traps or
informs, a user name, a security level, and whether to send traps or informs. The security level can be either
none (for no security), auth (for authentication only), or priv (for authentication and privacy).
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
n
Ensure that the users who will access the traps or informs are configured as SNMP users for both the
ESXi SNMP agent and the target management system.
n
If you are configuring informs, you need the engine ID for the SNMP agent on the remote system that
will receive the informs.
n
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.
