DGS-3630 Layer 3 Stackable Managed Switch CLI Reference Guide 53. Internet Group Management Protocol (IGMP) Proxy Commands (MI and EI Mode Only) 53-1 ip igmp proxy This command is used to enable the IGMP proxy function. Use the no form of this command to disable the IGMP proxy function. ip igmp proxy no ip igmp proxy Parameters None. Default By default, this option is disabled. Command Mode Global Configuration Mode. Command Default Level Level: 12. Usage Guideline The IGMP proxy only works in a simple tree topology. Make sure that there are no other multicast routers except for the proxy devices in the simple tree topology. When receiving IGMP report packets from a downstream interface, IGMP proxy will update its membership database which is generated by the merger of all subscriptions on any downstream interface. If the database is changed, the proxy device will send unsolicited reports or leaves from upstream interface. It can also send membership reports from the upstream interface when queried. Example This example shows how to enable IGMP proxy on the device. Switch# configure terminal Switch(config)# ip igmp proxy Switch(config)# 53-2 ip igmp proxy upstream This command is used to configure an interface as the upstream in IGMP proxy. Use the no form of this command to disable the IGMP proxy upstream function on the interface. ip igmp proxy upstream no ip igmp proxy upstream Parameters None. 741
