M4300 Intelligent Edge Series Fully Managed Stackable Switches Default Format Mode Enabled for VLAN 1. Disabled for all other VLANs. set igmp exclude-mrouter-intf [vlan-id] Global Config VLAN Config As of software version12.0.7, a designated mrouter port that is either detected dynamically or manually configured forwards the following information to the upstream router: • All IGMPv1, IGMPv2, and IGMPv3 PDUs. • All unknown multicast streams, that is, streams for which the switch did not receive IGMP membership. • All known multicast streams, that is, streams for which switch did receive IGMP membership and for which it updated its hardware MFDB table. As of software version 12.0.8. you can use the set igmp exclude-mrouter-intf command to prevent the switch from forwarding unknown and known IGMPv1 and IGMPv2 multicast streams unless the downstream port received an IGMPv1 or IGMPv2 membership. The switch still forward all IGMPv1, IGMPv2, and IGMPv3 PDUs. set igmp report-suppression Use this command to suppress the IGMP reports on a given VLAN ID. In order to optimize the number of reports traversing the network with no added benefits, a Report Suppression mechanism is implemented. When more than one client responds to an MGMD query for the same Multicast Group address within the max-response-time, only the first response is forwarded to the query and others are suppressed at the switch. Default Format Mode Disabled set igmp report-suppression vlan-id VLAN Config Parameter vlan-id Description A valid VLAN ID. Range is 1 to 4093. Command example: (NETGEAR Switch) #vlan database (NETGEAR Switch) (Vlan)#set igmp report-suppression ? Enter VLAN ID.
