The problem is clearly with the Meraki AP having incorrect SNMP settings. See below
snmpwalk -v 2c -c public 192.168.0.200 iso.3.6.1.2.1.1.1.0
iso.3.6.1.2.1.1.1.0 = STRING: "=Meraki MR28 Cloud Managed AP"
snmpwalk -v 2c -c public 192.168.0.155 iso.3.6.1.2.1.1.1.0
iso.3.6.1.2.1.1.1.0 = STRING: "Meraki MR33 Cloud Managed AP"
snmpwalk -v 2c -c public 192.168.0.160 iso.3.6.1.2.1.1.1.0
iso.3.6.1.2.1.1.1.0 = STRING: "Meraki MR76 Cloud Managed AP"
snmpwalk -v 2c -c public 192.168.0.167 iso.3.6.1.2.1.1.1.0
iso.3.6.1.2.1.1.1.0 = STRING: "Meraki MR33 Cloud Managed AP"
