M4300 Intelligent Edge Series Fully Managed Stackable Switches • Membership Interval. Specify the value for the group membership interval of IGMP snooping for the VLAN. The value must be the value in the Maximum Response Time field plus a value of 1 to 3600 seconds. • Maximum Response Time. Specify the value for the maximum response time of IGMP snooping for the VLAN. The range must be from 1 to the value in the Group Membership Interval field minus 1. The value in the Maximum Response Time must be greater than the value in the Group Membership Interval field. • Multicast Router Expiry Time. Specify the value of the multicast router expiration time of IGMP snooping for the VLAN. The range must be from 0 to 3600 seconds. • Report Suppression. From the menu, select to enable or disable the IGMP snooping report suppression mode for the VLAN. This mode allows for the suppression of IGMP reports that are sent by multicast hosts. The switch does so by building a Layer 3 membership table and sending only the essential reports to IGMP routers that must receive the multicast traffic. As a result, the multicast report traffic that is sent to the IGMP routers is reduced. The default is Disable. • Proxy Querier. From the menu, select to enable or disable the proxy querier for the VLAN. If disabled, the IGMP proxy query with source IP address 0.0.0.0 is not sent in response to an IGMP leave packet. The default is Enable. • Report Flood Mode. From the menu, select to enable or disable the report flooding mode on the VLAN. If enabled, IGMP Join/Leave PDUs that the VLAN receives from a host on a downstream port are forwarded to all other ports in the VLAN. The default is Enable. • Exclude Mrouter Interface Mode. From the menu, select to enable or disable the Exclude Mrouter Interface Mode. This selection specifies the type of information that is forwarded to the upstream multicast router interface. If enabled, the VLAN forwards IGMP Join/Leave PDUs that it receives on a downstream port to an upstream mrouter interface. In addition, the VLAN forwards a multicast data stream to an upstream mrouter interface only if that port already received an IGMPv1 or IGMPv2 membership message. The VLAN drops unknown multicast streams. The default is Enable. If disabled, the VLAN forwards IGMP Join/Leave PDUs, known multicast streams, and unknown multicast streams to the upstream mrouter interface. Note: For information about IGMP Plus mode for VLANs, see Configure IGMP Snooping for VLANs Automatically with IGMP Plus Mode on page 242. c. Click the Apply button. Your settings are saved. 6.
