1. I have the X420 to monitor https://www.controlbyweb.com/x420/manuals.html
2. it is possible to configure it through a web (172.21.31.41) interface here are the settings for the snmp
3. I generated the device.mib file to convert it to xlm to put it in Zabbix
4. I created the host in Zabbix "Bromley webrelay X420"
5. But nothing , i'm getting nothing

what must i do exactly in my zabbix server ?

snmp service is already on the zabbix server
