How to set up SNMP in Ubuntu server 18.04 to report access point activity to Zabbix dashboard?

I really need assistance in setting up SNMP to work with Zabbix on my dashboard. I have set up an Ubuntu 18.04 Zabbix server and have added over 18 agents. All virtual machines with Zabbix agents and they are working great!

Now I have gotten to the point where I need to have the AP's set up for Zabbix. I have followed the instructions and did the following so far:

sudo apt-get update
sudo apt-get install snmp snmp-mibs-downloader
sudo apt-get update
sudo apt-get install snmpd

I opened sudo nano /etc/snmp/snmp.conf and commented the following line:

#mibs :

Then I went into the configuration file:

sudo nano /etc/snmp/snmpd.conf

And from there I made changes to the following lines:

Listen for connections from the local system only
agentAddress udp:127.0.0.1:161 <--- commented this part.
Listen for connections on all interfaces (both IPv4 and IPv6)
agentAddress udp:161,udp6:[::1]:161 <--remove the comment from this line to make it work.

Then I set up the Zabbix dashboard side. I will attach pictures of the set-up.

1st zabbix dashboard menu:

2nd dashboard set-up menu:

I get the following error:

I will also attach picture that shows my meraki access point set-up.

Meraki AP SNMP set-up:

Lastly, I will add a picture that shows the Linux Zabbix server terminal set up on that config file.

Linux Zabbix Server:

I am stumped and cannot figure out why Zabbix still throwing out that error.

I have gone thru the Zabbix documentation but cannot find a solution to my problem.

Take these 2 steps :

1- install and config snmpd

2- install MIBs and config snmp conf file (not snmpd file)

Step 1: Run the following commands in the terminal:

Update all packages: sudo apt-get update

Install SNMP: sudo apt-get install snmpd

Edit snmpd.conf with text editor of your choice, we will be using nano: sudo nano /etc/snmp/snmpd.conf

It should look like this:

"#Listen for connections from the local system only"

"#agentAddress udp:127.0.0.1:161"

"Listen for connections on all interfaces (both IPv4 and IPv6"

"agentAddress udp:161,udp6:[::1]:161"

(#'s are important!!! the first two should have # and the last two should not!)

Configure rocommunity: rocommunity public (or whatever you like to use)

save and exit (ctrl+x , Yes , Enter)

Restart the SNMPD service: sudo service snmpd restart

Step 2:

sudo apt-get install snmp-mibs-downloader

sudo download-mibs

To have the new MIBs recognized by net-snmp, edit /etc/snmp/snmp.conf file as follows:

$ sudo nano /etc/snmp/snmp.conf
mibs +ALL
$

to test run :

snmptranslate -Tp on Terminal and youll get the MIB Trees

Go back to Zabbix you see it's working now !!!! :)
