Enabling Mld Snooping Fast-Leave Processing - HP 6125XLG Ip Multicast Configuration Manual

Step
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Configure the port as a static
member port.
4. Configure the port as a static
router port.

Enabling MLD snooping fast-leave processing

The MLD snooping fast-leave processing feature enables the switch to process MLD done messages
quickly. With this feature enabled, when the Layer 2 device receives an MLD done message on a port,
it immediately removes that port from the forwarding entry for the multicast group. Then, when the switch
receives MLD multicast address specific queries for that multicast group, it does not forward them to that
port.
When you enable the MLD snooping fast-leave processing feature, follow these guidelines:
In a VLAN, you can enable MLD snooping fast-leave processing on ports that have only one
•
receiver host attached. If a port has multiple receiver hosts attached, do not enable MLD snooping
fast-leave processing on this port. Otherwise, other receiver hosts attached to this port in the same
IPv6 multicast group cannot receive the IPv6 multicast data destined to this group.
You can enable MLD snooping fast-leave processing either on the current port in interface view or
•
globally for all ports in MLD-snooping view. If configurations are made in both interface view and
MLD-snooping view, the configuration made in interface view takes priority.
To enable MLD snooping fast-leave processing globally:
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable MLD snooping
fast-leave processing globally.
To enable MLD snooping fast-leave processing on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Enable MLD snooping
fast-leave processing on the
port.
