IGMP Snooping TCN Query Solicitation is disabled by default on the device, unless

the device is the Master Node in an EPSR ring, or is the Root Bridge in a Spanning

When the device is the Master Node in an EPSR ring, or the device is the Root

Bridge in a Spanning Tree, then IGMP Snooping TCN Query Solicitation is enabled

by default and cannot be disabled using the Global Configuration mode

command. However, Query Solicitation can be disabled for specified VLANs using

this command from the Interface Configuration mode. Select the VLAN you want

to disable in Interface Configuration mode then issue the no variant of this

command to disable the specified VLAN without disabling this feature for other

Global Configuration and Interface Configuration for a VLAN interface.

Once enabled, if the device is not an IGMP Querier, on detecting a topology

change, the device generates IGMP Query Solicit messages that are sent to all the

ports of the vlan configured for IGMP Snooping on the device.

On a device that is not the Master Node in an EPSR ring or the Root Bridge in a

Spanning Tree, Query Solicitation can be disabled using the no variant of this

command after being enabled.

If the device that detects a topology change is an IGMP Querier then the device will

generate an IGMP Query message.

Note that the no variant of this command when issued in Global Configuration

mode has no effect on a device that is the Master Node in an EPSR ring or on a

device that is a Root Bridge in a Spanning Tree. Query Solicitation is not disabled

for the device these instances. However, Query Solicitation can be disabled on a

per-vlan basis from the Interface Configuration mode.
