Global Configuration
Command Usage
• All systems on the subnet must support the same version. If there are legacy
devices in your network that only support Version 1, you will also have to
configure this switch to use Version 1.
• Some commands are only enabled for IGMPv2, including ip igmp
query-max-response-time and ip igmp query-timeout.
Example
The following configures the switch to use IGMP Version 1:
ip igmp snooping immediate-leave
This command enables IGMP immediate leave for specific VLAN. Use the no form
to disable the feature for a VLAN.
Syntax
[no] ip igmp snooping immediate-leave
Console(config)#ip igmp snooping vlan 1 static 224.0.0.12 ethernet 1/5
Console(config)#
Console(config)#ip igmp snooping version 1
Console(config)#
