If the upstream core/aggregation switch in the network is not a Meraki MS switch and is capable of both CDP and LLDP, topology may not display correctly. To resolve this please disable CDP on the non-Meraki switch's interfaces to the MS switch or switch stacks. Once disabled, topology will slowly correct itself as the LLDP information is updated by each node. https://documentation.meraki.com/MS/Monitoring_and_Reporting/Network_Topology
