Configuring IGMP snooping
Configuring the IGMP mode for a VLAN
If you specify an IGMP mode for a VLAN, it overrides the global setting.
To set the IGMP mode for VLAN 20 to active, enter the following commands.
TurboIron(config)#vlan 20
TurboIron(config-vlan-20)#multicast active
Syntax: [no] multicast active | passive
Configuring the IGMP version
Configuring the global IGMP version
When you globally enable IGMP snooping, you can specify IGMP V2 or IGMP V3 for the device. The
following command enables IGMP V3.
TurboIron(config)#ip multicast version 3
Syntax: [no] ip multicast version 2|3
If you do not specify a version number, IGMP V2 is assumed.
Configuring the IGMP version for a VLAN
You can specify the IGMP version for a VLAN. For example, the following commands configure VLAN
20 to use IGMP V3.
TurboIron(config)#vlan 20
TurboIron(config-vlan-20)#multicast version 3
Syntax: [no] multicast version 2 | 3
If no IGMP version is specified, then the globally-configured IGMP version is used. If an IGMP
version is specified for individual ports, those ports use that version, instead of the VLAN version.
Configuring the IGMP version for individual ports in a VLAN
You can specify the IGMP version for individual ports in a VLAN. For example, the following
commands configure ports 4, 5, and 6 to use IGMP V3. The other ports either use the IGMP version
specified with the multicast version command, or the globally-configured IGMP version.
TurboIron(config)#vlan 20
TurboIron(config-vlan-20)#multicast port-version 3 ethe 4 to 6
Syntax: [no] multicast port-version 2 | 3 <port-numbers>
Disabling IGMP snooping on a VLAN
When IGMP snooping is enabled globally, you can still disable it for a specific VLAN. For example,
the following commands cause IGMP snooping to be disabled for VLAN 20. This setting overrides
the global setting.
TurboIron(config)#vlan 20
TurboIron(config-vlan-20)#multicast disable-multicast-snoop
