How to find Engine ID in Mikrotik?

Question

Mikrotik

I welcome everyone!
When adding a host to Zabbix, I ran into such a problem. If you leave the "Engine ID" field on Mikrot empty, then the "SNMP" field in Zabbix will turn red. As soon as I substitute the default value 0x80003a8c04 (from the manual), the SNMP field lights up green, the traffic is collected, the graphs are drawn. The issue is that this identifier must be unique for each host to work correctly and must be generated automatically. Most likely the Engine ID is related to the MAC address of the device. How to find this ID?

Answer 1

There was a solution: I copied the serial number value from the RouterBoard tab and substituted it into the Engine ID. Zabbix picked up everything successfully.

Help.mikrotik.com has a comment about the Engine ID.

the engine-id field holds the suffix value of engine-id, usually, SNMP clients should be able to detect the value, as SNMP values, as read from the router. However, there is a possibility that this is not the case. In which case, the engine-ID value has to be set according to this rule: + , so as an example, if you have set 1234 as suffix value you have to provide 80003a8c04 + 31323334, combined hex (the result) is 80003a8c0431323334

for conversion, you can use any service with similar functionality or write your own script
