ESXi 4.1 and 5.0 Enable SNMP

SSH to host and edit the SNMP.XML file:

vi /etc/vmware/snmp.xml

Make the following changes:

<config>
<snmpSettings>
<enable>true</enable>
<communities>public</communities>
<targets>192.168.1.100@public</targets>
</snmpSettings>
</config>

Restart management agents with the following command:

/etc/init.d/hostd restart

On ESXi 5.1 and 5.5 enable SNMP

SSH to host and run the following command:

esxcli system snmp set --communities=public --enable=yes --targets=192.168.1.100/public

Test SNMP trap

vicfg-snmp --server <ESXiServerIP> --username root --password <Password> --test

Reviewing the SNMP configuration

When I look at my SNMP configuration using vCLI (once again, this is a read operation so I can use vCLI), I see the following.

vi-admin@vma:~> vicfg-snmp --server <ESXiServerIP> --username root --password <Password> -s

Current SNMP agent settings:
Enabled : 1
UDP port : 161

Communities :
public

Notification targets :
192.168.1.100@162/public

Options :
EnvEventSource=indications
