Applied update to all esxi 6 host and now snmp wont start up

We applied a patch to all of the ESXi 6 host and now SNMP wont start. we get the error: Hostservicesystem.start for object servicesystem-31
I found an article that says to edit the snmp.xml file and add an entry to it, but not sure how to edit this file for each host or is there something else I should do?

WinSCP or VI.

Ok I saw that about vi but just not sure how to use it to edit the snmp.xml file which is in the /etc/VMware folder.
I don't want to screw up the host that's for sure..

if you do not know of to use vi.

Download and Install WinSCP on a Windows Computer, connect to the host, and select the file, and Edit.

I still cant get the snmp server to start on any of the host even after following this doc:

Any ideas on how I can get the snmp server to start again..
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
is the snmp.xml file correct ?

are you confident that this is the fix?
vmichAuthor Commented:
No I am not I just found an article that said this could be the issue..
The snmp was working until we applied an update to all of the host to take them to ESXi 6 update 1
vmichAuthor Commented:
just not sure what to try to get the snmp server to start again??
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Okay, I would escalate to VMware Support, as to the cause, if it worked before the Update, and now fails after, maybe another bug has been found.
vmichAuthor Commented:
yeah I am on hold with them waiting..
vmichAuthor Commented:
Well found out what we needed to do from VMware support.. They said they have not seen this issue yet coming from ESXi 6 update 1 but they gave me the following command to run to enable the SNMP server again: esxcli system snmp set -e true
They don't know what caused this but said it maybe because when engineering did the update, they set the default to not running...
Also they said that they just released ESxi 6 update 1A 2 days ago.. Go figure, I applied U1 to all of our host 2 days a ago.... :(
