DHCP option 60

...

Vendor Class Identifier

(ChatGPT) DHCP 옵션 60은 클라이언트 식별 (Vendor Class Identifier, VCI)을 정의하는 데 사용되는 옵션입니다. 이 옵션은 클라이언트 장치가 특정한 공급업체 또는 유형의 장치임을 DHCP 서버에 알리기 위해 사용됩니다. DHCP 서버는 이 정보를 사용하여 특정 클라이언트 유형에 맞는 DHCP 옵션을 제공합니다.

https://community.cisco.com/t5/wireless-mobility-knowledge-base/configuring-dhcp-option-43-and-option-60/ta-p/3143572
Cisco IOS based DHCP scopes allow only one option 60 string (VCI) per scope, So you may not want to use it if you have different series of APs in the same subnet and the VCI of all the APs is different and all of them have to be accomodated in the same scope.
