SNMP Walk works, but Get does not

I am trying to use an RB100AHx4 on 6.47.1 to grab a Mimosa B11 radio’s signal strength with snmp-get.

The Walk command works successfully:

/tool snmp-walk address=10.10.10.10 community=public
OID                                                                     TYPE             VALUE

1.2.840.10036.1.1.1.3.9                                                 integer          1

But the Get command does not:

/tool snmp-get address=10.10.10.10 oid=1.3.6.1.4.1.43356.2.1.2.6.6.0 community=public
error - contact MikroTik support and send a supout file (3)

I found a workaround using snmp-walk:

:do {
:execute script={/tool snmp-walk 10.10.10.10 oid=1.3.6.1.4.1.43356.2.1.2.6.6 community=public} file=oid_data.txt
/delay 5
:local output [/file get oid_data.txt contents]
:local signal [/put [:pick $output 129 133]]
}
/code]

nice, thank you for sharing

Can you post the output of with oid of the line giving correct result?
