What kind of protocol is used in showing non Meraki products in Topology

[RobustMeraki]

Our customer wants to know what protocoll is being used in showing non Meraki products in topology. 

The question was if we are using CLLP Protocol (not sure if I am right) or SNMP. He meant here that CLLP shows basic details of the on Meraki product in topology whereas SNMP shows more detail of the product in the topology.

I would presume you mean CDP and LLDP.  LLDP will be the one used for non Meraki/Cisco devices

[Brash]

As stated above, CDP is a Cisco proprietary protocol while LLDP is an open standard. LLDP is what is used to read information about connected non Meraki/Cisco devices.

SNMP is not used for collecting this information.
