IP multicast traffic floods out all ports; IGMP does not appear to filter traffic

The IGMP feature does not operate if the switch or VLAN does not have an IP address configured manually or obtained through DHCP/Bootp. To verify whether an IP address is configured for the switch or VLAN, do one of the following:

• Try using the WebAgent: If you can access the WebAgent, then an IP address is configured.
• Try to telnet to the switch console: If you can Telnet to the switch, an IP address is configured.
• Use the switch console interface: From the Main Menu, check the Management Address Information screen by clicking on:
