Configuring A Port As A Simulated Member Host; Enabling Fast-Leave Processing - HP FlexFabric 5700 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 MLD report when you complete the configuration.
It responds to MLD general queries with MLD reports.
•
It sends an MLD done message when you remove the configuration.
•
When you perform this task, make sure the MLD version and MLD snooping version on the simulated host
are the same.
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.
NOTE:
Unlike a static member port, a port configured as a simulated member host ages out like a dynamic
member port.

Enabling fast-leave processing

This feature enables the switch to immediately remove a port from the forwarding entry for an IPv6
multicast group when the port receives a done message.
Configuration guidelines
When you enable fast-leave processing feature, follow these guidelines:
Do not enable fast-leave processing on a port that have multiple receiver hosts attached in a VLAN.
•
If fast-leave processing is enabled, after a receiver host leaves an IPv6 multicast group, the other
receivers cannot receive IPv6 multicast data for the group.
• You can enable fast-leave processing for the current port in interface view or globally for all ports
in MLD-snooping view. The configuration made in interface view takes priority over the
configuration made in MLD-snooping view.
Enabling fast-leave processing globally
Step
1. Enter system view.
2. Enter MLD-snooping view.
3. Enable fast-leave processing
globally.
