2 Configure the SNMP Agent to Send Traps on page 52
You can use the ESX/ESX embedded SNMP agent to send virtual machine and environmental traps to
management systems. To configure the agent to send traps, you must specify a target address and
community.
3 Configure the SNMP Agent for Polling on page 53
If you configure the ESX/ESXi embedded SNMP agent for polling, it can listen for and respond to requests
from SNMP management client systems, such as
GET
requests.
Configure SNMP Communities
Before you enable the ESX/ESXi embedded SNMP agent, you must configure at least one community for the
agent.
An SNMP community defines a group of devices and management systems. Only devices and management
systems that are members of the same community can exchange SNMP messages. A device or management
system can be a member of multiple communities.
Prerequisites
SNMP configuration for ESX/ESXi requires the vSphere CLI. For information on installing and using the
vSphere CLI, see vSphere Command-Line Interface Installation and Reference Guide.
Procedure
u
From the vSphere CLI, type
vicfg-snmp.pl --server <hostname> --username <username> --password <password> -c <com1>
.
Replace <com1> with the community name you wish to set. Each time you specify a community with this
command, the setings you specify overwrite the previous configuration. To specify multiple communities,
separate the community names with a comma.
For example, to set the communities public and internal on the host host.example.com, you might type
vicfg-snmp.pl --server host.example.com --username user --password password -c public,
internal
.
Configure the SNMP Agent to Send Traps
You can use the ESX/ESX embedded SNMP agent to send virtual machine and environmental traps to
management systems. To configure the agent to send traps, you must specify a target address and community.
To send traps with the SNMP agent, you must configure the target (receiver) address, community, and an
optional port. If you do not specify a port, the SNMP agent sends traps to UDP port 162 on the target
management system by default.
