Hello@mary_OM,
There are three types of service sets:
l AP management: manages APs. APs determine whether to forward data upstream
according to the data forwarding status of a management service set.
l AC management: manages ACs. An AC identifies users according to VLAN
information. After the AC determines that a user is in a management service set during
authentication, it identifies the user as a management user and allows the user to access
the AC using Telnet.
l Service type: manages WLAN services but not APs or ACs.
Glad to help you! Any further questions, let us know.
