Configure the IGS Version

The operating version of an IGS switch on a VLAN can be V1, V2, or V3. This section describes the configuration of IGMP version on a VLAN. If you have questions about the topology used in this section, see Flow-Based Configuration Example. For the default settings, see Default Settings.

1. On DUT1, configure the multicast forwarding mode for IGS as MAC-based.

   SEFOS# configure terminal
   SEFOS(config)# snooping multicast-forwarding-mode mac
   

2. Disable GMRP.

   SEFOS(config)# set gmrp disable
   

3. Enable IGS.

   SEFOS(config)# ip igmp snooping
   

4. Configure VLAN 2 in the switch.

   SEFOS(config)# vlan 2
   

5. Configure the static VLAN entry (VLAN 2) with the required ports.

   SEFOS(config-vlan)# ports extreme-ethernet 0/1-2
   

6. Configure the version of IGS as V2 for the VLAN.

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

7. Configure VLAN 3 in the switch.

   SEFOS(config)# vlan 3
   

8. Configure the static VLAN entry (VLAN 3) with the required ports.

   SEFOS(config-vlan)# ports extreme-ethernet 0/3-4
   

9. Configure the version of IGS as V3 for the VLAN.

   SEFOS(config-vlan)# ip igmp snooping version v3
   SEFOS(config-vlan)# exit
   

10. Enter Interface Configuration mode for Gigabit Ethernet interface 0/1.

    SEFOS(config)# interface extreme-ethernet 0/1
    

11. Set the PVID as VLAN 2.

    SEFOS(config-if)# switchport pvid 2
    

12. Bring up the interface.

    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# exit
    

13. Enter Interface Configuration mode for Gigabit Ethernet interface 0/2.

    SEFOS(config)# interface extreme-ethernet 0/2
    

14. Set the PVID as VLAN 2.

    SEFOS(config-if)# switchport pvid 2
    

15. Bring up the interface.

    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# exit
    

16. Enter Interface Configuration mode for Gigabit Ethernet interface 0/3.

    SEFOS(config)# interface extreme-ethernet 0/3
    

17. Set the PVID as VLAN 3.

    SEFOS(config-if)# switchport pvid 3
    

18. Bring up the interface.

    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# exit
    

19. Enter Interface Configuration mode for Gigabit Ethernet interface 0/4.

    SEFOS(config)# interface extreme-ethernet 0/4
    

20. Set the PVID as VLAN 3.

    SEFOS(config-if)# switchport pvid 3
    

21. Bring up the interface.

    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# end
    

22. Review the IGS-related configurations.
