E911 Location requires a unique identifier for a switch stack member

[DennisVaggalis]

Customer has MS Teams Voice and is dedicating a Cisco 2960 switch to each floor for E911 Location Services.  If they replace the Cisco's for MS225 (Physically Stacked), does each stack member have a unique identifier (MAC addr) that can be used to identify the whole switch or does each switch port need to be assigned separately?

Do you know what information they are using for the service? LLDP/CDP or is there active polling with SNMP for instance? Even for stacked switches the LLDP/CDP should identify the chassis that is directly connected. With SNMP it would depend on the mode used and model.
