In a multicast control method, when an SSID or a BSSID of a specified VAP that will be delivered to an access point AP enables a multicast control function, an AC sends to the AP a CAPWAP multicast control message that includes multicast control enabling information, so that the AP creates a multicast control table according to the CAPWAP multicast control message that includes the multicast control enabling information and performs multicast control according to the multicast control table. With the method, the AC is responsible for delivering a multicast control policy to the AP, and the AP implements multicast replication and WLAN station rights control, which relieves the multicast control and multicast replication pressure on the AC effectively, improves the utilization of the network bandwidth, and overcomes the operator's difficulties in meeting multicast service requirements in the WLAN thoroughly.

Multicast control method and apparatus

A method and an apparatus for sending a key on a Wireless Local Area Network (WLAN) is provided. In a scenario where an Access Server is separate from an Access Controller, the Access Controller may send a master key of a specified WLAN station to the AC and trigger the AC to agree with the station on a transient key. The method includes: when receiving the master key of the WLAN station sent from an AAA server, searching a station information table for an IP address of an AC associated with the station; sending a message to the AC to instruct the AC to perform a 4-way handshake with the station to agree on a transient key, where the third message carries the master key of the station, a 4-way handshake triggering bit, and a MAC address of the WLAN station.
