Displaying IGMP Interface Detailed Membership Using CLI Commands For information about the CLI command that performs this function, see the following chapter in the CLI Reference Guide: • IGMP Commands The following table summarizes the equivalent CLI commands for this feature. Table 12-18. IGMP Interface Detailed Membership Command CLI Command show ip igmp interface membership Description Displays the list of interfaces that have registered in the multicast group. Proxy Interface The purpose of IGMP Proxy is to enable a multicast router to learn multicast group membership information and be able to forward multicast packets based upon the group membership information. The IGMP Proxy is capable of functioning only in certain topologies that do not require Multicast Routing Protocols (i.e. DVMRP, PIM-DM, and PIM-SM) and that have a tree-like topology, as there is no support for features like spanning tree to correct packet route loops. The Proxy Interface menu page contains links to web pages that define and display Proxy Interface parameters and data. To display this page, click IPv4 Multicast →IGMP →Proxy Interface in the tree view. Following are the web pages accessible from this menu page: • IGMP Proxy Interface Configuration • IGMP Proxy Configuration Summary • IGMP Proxy Interface Membership Info • IGMP Proxy Interface Membership Info Detailed IGMP Proxy Interface Configuration The IGMP Proxy is used by IGMP Router (IPv4 system) to enable the system to issue IGMP host messages on behalf of hosts that the system discovered through standard IGMP router interfaces. Thus, this feature acts as proxy to all hosts residing on its router interfaces. Use the IGMP Proxy Interface Configuration page to configure IGMP proxy for an interface. You must have configured at least one router interface before configuring or displaying data for an IGMP proxy interface, and it should not be an IGMP routing interface. To display the page, click IPv4 Multicast →IGMP →Proxy Interface →Interface Configuration in the tree view. Configuring IP Multicast 743
