Configure the IGS Version

You can configure the operating version of the IGS switch for a specific VLAN as v1, v2, or v3. By default, the operating version of the IGS switch for all of the VLANs is v3. Before you can configure IGS features, you must already configure your network environment, as described in Topology Example.

1. Enter the configure mode for the VLAN interface.

   SEFOS# configure terminal
   SEFOS(config)# vlan 4
   

2. Configure the IGS version.

   SEFOS(config-vlan)# ip igmp snooping version v2
   SEFOS(config)# end
   

3. Review the configuration.

   SEFOS# show ip igmp snooping vlan 4
