A.all Wi-Fi devices on the WLAN send directly received signal strength indication （RSSI） information to the Cisco Wireless Location Appliance through SNMP
B.an AP collects RSSI information which is forwarded to wireless controllers through LWAPP. Wireless controllers forward aggregated RSSI to the location appliance through SNMP
C.the APs collect received signal strength indication （RSSI） information from all Wi-Fi devices and forward the information to the Cisco Wireless Location Appliance through the LWAPP
D.the Cisco WLAN controllers bypass the received signal strength indication （RSSI） information from all Wi-Fi devices to the Cisco Wireless Location Appliance through the LWAPP

A.AutoQoS can be configured from a different subinterface if the DLCI is already assigned to one subinterface 
B.Multilink PPP (MLP) over Frame Relay must be manually configured on low speed DLCIs 
C.for low-speed Frame Relay DLCIs with Frame Relay-to ATM interworking, the AutoQoS cannot be configured if a virtual template is already configured for the DLCI 
D.AutoQoS can be configured on a Frame Relay DLCI only if a map class is attached to the DLCI
