Command Usage
• If version exclusive is disabled on a VLAN, then this setting is based on the global setting. If it is
enabled on a VLAN, then this setting takes precedence over the global setting.
• When this function is disabled, the currently selected version is backward compatible (see the
ip igmp snooping version command.
Example
Console(config)#ip igmp snooping version-exclusive
Console(config)#
ip igmp snooping vlan general-query-suppression
This command suppresses general queries except for ports attached to downstream multicast
hosts. Use the no form to flood general queries to all ports except for the multicast router port.
Syntax
[no] ip igmp snooping vlan vlan-id general-query-suppression
vlan-id - VLAN ID (Range: 1-4093)
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
• By default, general query messages are flooded to all ports, except for the multicast router
through which they are received.
• If general query suppression is enabled, then these messages are forwarded only to
downstream ports which have joined a multicast service.
Example
Console(config)#ip igmp snooping vlan 1 general-query-suppression
Console(config)#
ip igmp snooping vlan immediate-leave
This command immediately deletes a member port of a multicast service if a leave packet is
received at that port and immediate-leave is enabled for the parent VLAN. Use the no form to
restore the default.
Syntax
[no] ip igmp snooping vlan vlan-id immediate-leave
vlan-id - VLAN ID (Range: 1-4093)
