Configure a Multicast Router VLAN
You can configure an interface to forward the snooped IGMP packets from a specific VLAN 
only to the multicast router that is connected to the interface. The configuration is not needed 
most of the time since the switch automatically detects a multicast router and forwards the 
IGMP packets accordingly. It is needed only when you want to make sure that the multicast 
router always receives IGMP packets from the switch in a complex network. 
To configure a multicast router VLAN: 
1. 
Launch a web browser.

Enter http://<ipaddress> in the web browser address field.
