Configuring IGMP snooping

If you do not enter either active or passive, the passive mode is assumed.

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.

PowerConnect(config)# vlan 20

PowerConnect(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.

PowerConnect(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.

PowerConnect(config)# vlan 20

PowerConnect(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.

PowerConnect(config)# vlan 20

PowerConnect(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.

PowerConnect(config)# vlan 20
