Configuring A Port As A Simulated Member Host; Enabling Fast-Leave Processing - HP FlexFabric 5950 series Configuration Manual

Configuring a port as a simulated member host

When a port is configured as a simulated member host, it is equivalent to an independent host in the
following ways:
•
It sends an unsolicited IGMP report when you complete the configuration.
•
It responds to IGMP general queries with IGMP reports.
•
It sends an IGMP leave message when you cancel the configuration.
The version of IGMP running on the simulated member host is the same as the version of IGMP
snooping running on the port. The port ages out in the same way as a dynamic member port.
To configure a port as a simulated member host:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Configure the port as a
simulated member host.

Enabling fast-leave processing

This feature enables the device to immediately remove a port from the forwarding entry for a
multicast group when the port receives a leave massage.
Configuration restrictions and guidelines
When you enable fast-leave processing, follow these restrictions and guidelines:
•
Do not enable fast-leave processing on a port that has multiple receiver hosts in a VLAN. If
fast-leave processing is enabled, the remaining receivers cannot receive multicast data for a
group after a receiver leaves that group.
•
You can enable fast-leave processing globally for all ports in IGMP-snooping view or for a port
in interface view. For a port, the port-specific configuration takes priority over the global
configuration.
Enabling fast-leave processing globally
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable fast-leave processing
globally.
