for various multimedia applications, you can use the switch to reduce unnecessary bandwidth usage on a per-port basis by configuring IGMP (Internet Group Management Protocol controls). In the factory default state (IGMP disabled), the switch simply floods all IP multicast traffic it receives on - HP 6120XG | HP ProCurve Series 6120 Blade Switches Multicast and Routing Guide - Page 23
Note IGMP configuration on the switches covered in this guide operates at the VLAN context level. If you are not using VLANs, then configure IGMP in VLAN 1 (the default VLAN) context.

. The switches support Data-Driven IGMP ("Smart" IGMP), and Fast-Leave is enabled in the default configuration. They Connected to only one end node 2. The end node currently belongs to a multicast group; i.e. is an IGMP client 3. The end node subsequently leaves the multicast group Then the switch - HP 6120XG | HP ProCurve Series 6120 Blade Switches Multicast and Routing Guide - Page 34
-Leave does not operate on port A6. Default (Enabled) IGMP Operation Solves the "Delayed Leave" Problem. Fast-leave IGMP is enabled by default. When Fast-leave is disabled and multiple IGMP clients are connected to the same port on an IGMP device (switch or router), if only one IGMP client joins - HP 6120XG | HP ProCurve Series 6120 Blade Switches Multicast and Routing Guide - Page 35
switch port that is connected to multiple end nodes. (This feature does not activate on ports where the switch detects only one end node).

To view a non-default IGMP forced fast-leave configuration on a VLAN, use the show running- - HP 6120XG | HP ProCurve Series 6120 Blade Switches Multicast and Routing Guide - Page 36
the delay period. In practice, this is rarely necessary on the switches covered in this guide, which support data-driven IGMP.

in this range are termed "well-known" addresses and are reserved for predefined host groups. IGMP does not filter these addresses, so any packets the switch receives for such addresses are flooded out all ports assigned to the VLAN on which they were received (except the port on which the packets - HP 6120XG | HP ProCurve Series 6120 Blade Switches Multicast and Routing Guide - Page 39
