The igmp version command specifies an IGMP version on an interface.
The undo igmp version command restores the default IGMP version on an interface.
By default, an interface runs IGMPv2.
| Parameter | Description | Value |
|---|---|---|
| version | Specifies the IGMP version running on the interface. | The value is integer that ranges from 1 to 3. |

Usage Scenario
The switch can only identify IGMP messages of a version earlier than its own IGMP version. To ensure normal IGMP operation, set on the switch an IGMP version the same as or alter than that running on member hosts.
If multiple switches exist on a shared network segment, configure the same IGMP version on all switch interfaces connected to hosts. Otherwise, errors may occur in IGMP operation because interfaces running different IGMP versions send packets with different formats.
Prerequisites
IP multicast routing has been enabled using the multicast routing-enable command.
Precautions
This command functions in the same way as the version command used in the IGMP view, except that the configuration in the IGMP view is globally valid, whereas the configuration in the interface view is valid only for the specified interface. The configuration in the interface view takes precedence over the configuration in the IGMP view. The configuration in the IGMP view is used only when the configuration in the interface view is not done.
