2-LAYER MULTICAST GROUP MANAGING METHOD USING IGMP PACKET INFORMATION IN ETHERNET SWITCH |
摘要 |
PURPOSE: A 2-layer multicast group managing method using IGMP packet information in an ethernet switch is provided to allow hosts, which do not support GMRP or GVRP, to register a desired 2-layer multicast group and virtual LAN by using an IGMP packet of an IP layer. CONSTITUTION: An ethernet switch makes an MAC look-up with a destination MAC address of a frame received from a port set in an access mode or in a hybrid mode(601,602). The ethernet switch determines whether a range of the destination MAC address corresponds to 01:00:5e:00:00:00-01:00:5e:7f:ff:ff(603). If it is determined to be an IGMP packet, the ethernet switch searches a mapped virtual LAN ID by searching a mapping table with the group address in the IGMP packet(605-607). It is determined whether a type field value in the IGMP packet relates to a group registration request or deletion(608). If the field value relates to the registration request, the ethernet switch generates a virtual LAN table entry(609,610).
