Cli Examples - Dell PowerConnect M6348 Configuration Manual

The IGMP proxy offers a mechanism for multicast forwarding based only on IGMP membership
information. The router must decide about forwarding packets on each of its interfaces based on the
IGMP membership information. The proxy creates the forwarding entries based on the membership
information and adds it to the multicast forwarding cache (MFC) in order not to make the forwarding
decision for subsequent multicast packets with same combination of source and group.

CLI Examples

The CLI component of the Dell switch allows the end users to configure the network device and to view
device settings and statistics using a serial interface or telnet session.
Example #1: Configuring IGMP Proxy on the Router
This command enables the IGMP Proxy on the router. To enable IGMP Proxy on the router no multicast
routing protocol should be enabled and also multicast forwarding must be enabled on the router. Use
these commands from the Interface mode:
console#configure
ip routing
ip multicast
ip igmp
interface vlan 15
ip igmp-proxy
Additional configuration options are available for the igmp-proxy command:

The value of the unsolicited report interval can range from 1 to 260 seconds. The default is 1 second. Use
this command from the Interface mode.
Example #2: View IGMP Proxy Configuration Data
