Enabling Igmp Snooping Fast-Leave Processing - HP 5920 series Configuration Manual

To configure static ports:
Step
1. Enter system view.
2. Enter Ethernet interface view
or aggregate interface view.
3. Configure the port as a static
member port.
4. Configure the port as a static
router port.

Enabling IGMP snooping fast-leave processing

The IGMP snooping fast-leave processing feature enables the switch to process IGMP leave messages
quickly. When a port that is enabled with the IGMP snooping fast-leave processing feature receives an
IGMP leave message, the switch immediately removes that port from the forwarding entry for the
multicast group specified in the message. Then, when the switch receives IGMP group-specific queries for
that multicast group, it does not forward them to that port.
When you configure the IGMP snooping fast-leave processing feature, follow these guidelines:
In a VLAN, you can enable IGMP snooping fast-leave processing on ports that have only one
•
receiver host attached. If a port has multiple hosts attached, you should not enable IGMP snooping
fast-leave processing on this port. Otherwise, other receiver hosts attached to this port in the same
multicast group cannot receive the multicast data destined to this group.
• You can enable IGMP snooping fast-leave processing either for the current port in proper interface
view or globally for all ports in IGMP-snooping view. If the configurations are made both in
interface view and IGMP-snooping view, the configuration made in interface view takes priority.
To enable IGMP snooping fast-leave processing globally:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable IGMP snooping
fast-leave processing globally.
To enable IGMP snooping fast-leave processing on a port:
Step
1. Enter system view.
2. Enter Ethernet interface view
or aggregate interface view.
3. Enable IGMP snooping
fast-leave processing on the
port.
