On the screen you sent, only set the "SNMP Community". This field works as an identifier, and you can set a custom community or use the default, which is "public".
In addition to registration at Zabbix, it is essential to activate the service at Blockbit. To do this, use the command: enable-snmp via CLI.
You also need to set up Zone Protection to allow SNMP traffic from the network where Zabbix is located.
