Configuring ESXi for SNMPv3

 

Hello Guys,

In this post I will show you how to configure and enable SNMPv3 traps in VMware vSphere 6.7 or later.

First Step:  Get the MAC Address on ESXi Host:

Command:

esxcfg-info | grep "Mac Address"

Result:

LoadOemStrings: SMBIOS OEM String at 5 failed: Unable to get node: Sysinfo error: FailureSee VMkernel log for details.
               |----Mac Address.....................................00:25:b5:22:a1:02
               |----Mac Address.....................................00:50:56:67:32:7c
               |----Mac Address.....................................00:50:56:6c:63:c8
                  |----Mac Address..................................00:25:b5:22:a1:02
                  |----Mac Address..................................00:50:56:67:32:7c
                  |----Mac Address..................................00:50:56:6c:63:c8
            |----World Command Line.................................grep Mac Address

Second Step:  With the MAC Address configure the Engine ID:

esxcli system snmp set -E=25b522a102

Third Step:  Set the authentication protocol:

esxcli system snmp set -a=MD5

Four Step:  Set the encryption protocol:

esxcli system snmp set -x=AES128

Fifth Step:  Indicate the authentication and encryption password:

Command:

esxcli system snmp hash -r -A SnMpV3BnClDx -X SnMpV3BnClDx

Result:

   Authhash: 09851d1332df44bf48e73e5112a60c7b
   Privhash: 09851d1332df44bf48e73e5112a60c7b

Sixth Step:  Indicate the user with the Authhash and Privhash:

esxcli system snmp set --users SNMPV3HYPFLEX/09851d1332df44bf48e73e5112a60c7b/09851d1332df44bf48e73e5112a60c7b/priv

Seventh Step: Enable SNMP

esxcli system snmp set --enable true

eighth Step: Enable SNMPv3

esxcli system snmp set --v3targets 172.27.254.72@161/SNMPV3HYPFLEX/priv/trap 

That's all for this post.
