SNMP v3 error with new Cacti Install Router os 6.18

RouterOS General
1

The working device CRS1 (Version 6.12) sends a valid value for
msgAuthoritativeEngineTime in its “SNMP report” packet as an answer to the
initiating get-request. This value is then reused for all subsequent SNMP
request/responses during that session.

The failing device CCR1 (Version 6.18) sends a value of “0” for
msgAuthoritativeEngineTime in its “SNMP report” packet as an answer to the
initiating get-request. In this case, the previously existing value for
msgAuthoritativeEngineTime (stemming from last SNMP request against CRS1) is used. This gives the bad results.

So we have questions:

  1. Why does one device return “valid data”, while the other one does not? Is
    there perhaps an issue with the firmware of CRR1?

Can anybody help..
I have Mikrotik RB750 and RB2011 SNMP doesn’t work, i tried package versions, 6.27, 6.9, 6.25..
snmpwalk doesn’t give any positive results.
config is completely correct no rules nothing that could hinder. (snmpcommunity + 0.0.0.0/0 access and snmp enable)

many thanks beforehand

I was able to get it to work with Cacti however, we had to poll a single spine process for each host.

There have been issues with SNMP in a few older versions…

What I recommend:
Use latest RouterOS with latest firmware (RouterBOOT).

I have had issues where SNMP didnt work because RouterBOOT was older version, even when RouterOS was newest version.
