`multicast6`

Configures the multicast listening discovery (MLD) mode on the device to active or passive.

Syntax

multicast6 [ active | passive ]

no multicast6 [ active | passive ]

Command Default

MLD mode is passive.

Parameters

active: Configures MLD active mode, that is, the device actively sends out MLD queries to identify IPv6 multicast groups on the network, and makes entries in the MLD table based on the group membership reports it receives from the network.
passive: Configures MLD passive mode, that is, the device forwards reports to router ports that receive queries. MLD snooping in the passive mode does not send queries. However, it does forward queries to the entire VLAN.

Modes

VLAN configuration mode

Usage Guidelines

The MLD mode configured on a VLAN overrides the mode configured globally.

The no form of this command returns the device to the previous MLD mode.

Examples

The following example configures MLD mode as active on VLAN 20.

device(config)# vlan 20
device(config-vlan-20)# multicast6 active
