set mld portFastLeave

Use this command to enable port fast leave on the specified port or range of ports.

Syntax

set mld portFastLeave port-list

Parameters

port-list port ID or a range of port IDs.

Defaults

None.

Mode

All command modes.

Usage

Port fast leave is an MLD mechanism that immediately removes the layer 2 LAN interface from the forwarding table upon receiving an MLD done message for the multicast group without first sending out general queries to the interface. Enable MLD port fast leave only on ports with only one host connected. This prevents the inadvertent dropping of other hosts that were connected to the same layer 2 LAN port but were still interested in receiving multicast traffic directed to that group.

The port fast leave setting is applied to both IGMP and MLD regardless of which protocol it is set in.

Example

This example enables the port fast leave feature on ports ge.1.5-8:

System(rw)->set mld portFastLeave ge.1.5-8
System(rw)->
