Defines the time the Multicast router waits to receive a message before it times out. The possible field values are: Enable — Enables IGMP Snooping on the VLAN. The possible field values are: Enabled — An IGMP Querier is enabled on the VLAN. The possible field values are IGMPv2 and IGMPv3 (The default is IGMPv2). IGMP Snooping and Static Router Ports Settings Page The IGMP Snooping and Static Router Ports Settings Page contains the following fields: Field VLAN ID VLAN Name Leave Timer Description Specifies the VLAN ID Displays the user-defined VLAN name. Defines the time a host waits to receive a Join message from another station after requesting to leave the IGMP group, prior to timing out. If a Leave Timeout occurs, the switch notifies the Multicast device to stop sending traffic The Leave Timeout value is either user-defined, or an immediate leave value. Defines the time the host waits to receive a message before timing out. Defines the time the Multicast router waits to receive a message before it times out. The possible field values are: Host Timeout Router Timeout State 77 DGS-3100 Series Gigabit Stackable Managed Switch User Manual Field Description Enable — Enables IGMP Snooping on the VLAN. Disable — Disables IGMP Snooping on the VLAN Defines the IGMP Querier status on the VLAN. The possible field values are: Enabled — Enables an IGMP Querier on the VLAN. Indicates the units and port numbers defined as forbidden router ports. IGMP Snooping and Static Router Port Settings are defined, and the device is updated. 78 DGS-3100 Series Gigabit Stackable Managed Switch User Manual Defining MLD Snooping Multicast Listener Discovery (MLD) Snooping performs the same function for IPv6 multicast routers as IGMP Snooping does for IPv4 multicast routers. The device supports two versions of MLD Snooping: – MLDv1 Snooping detects MLDv1 control packets and sets up traffic bridging based on IPv6 destination multicast addresses. In a similar approach to IGMP snooping, MLD frames are snooped as they are forwarded by the switch from stations to an upstream multicast router. This facility allows a switch to determine the following: – Where (on which ports) stations interested in joining a specific multicast group are located – Where (on which ports) multicast routers sending multicast frames are located This knowledge is used to exclude irrelevant ports (ports for which no stations have registered to receive a specific multicast group) from the forwarding set of an incoming multicast frame. Two port types can be defined in the system: – Host port - a port connected to an end-node device running an IGMP/MLD (multicast communication) application. – Multicast Router (mrouter) port - a port connecting multicast router ports to the switch. This port receives all IGMP/MLD control packets (reports and queries) as well as all multicast data traffic associated with dynamic Multicast groups.
