Abstract: The present invention provides a data forwarding method and apparatus, and an access device. The method is as follows: first, all ports on an access device are grouped into two port groups, and the access device stores a correspondence among a VLAN, a port identifier, and a port group to which a port identified by the port identifier belongs; the access device receives a packet, identifies a port group to which a port that receives the packet belongs as a first port group, and obtains a VLAN from the packet; and the access device obtains a corresponding port identifier from the correspondence by using the obtained VLAN and a second port group, and forwards the packet through a port identified by the obtained port identifier.

Abstract: A multicast processing method, device, and system are provided. The method includes: blocking a port 1, where the port 1 is one of an egress port and an ingress port, and the other of the egress port and the ingress port is a root port; receiving a join packet from the ingress port, wherein the packet is used for a multicast user to request joining multicast; and establishing, according to multicast information of the multicast included in the join packet and port information of the ingress port, a forwarding table entry for forwarding data of the multicast from the egress port to the ingress port. Through embodiments of the present invention, an effect of shortening the multicast service recovery time is realized.
