## Configure Proxy Reporting in Flow-Based Configurations

When proxy reporting is enabled, the switch generates reports and forwards them to the router based on the available host information. 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. Enable proxy reporting.

       SEFOS(config)# ip igmp snooping proxy-reporting

5. Configure `VLAN 2` in the switch.

       SEFOS(config)# vlan 2

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

       SEFOS(config-vlan)# ports extreme-ethernet 0/1-4

7. Configure the static router port as P2 for the VLAN.

       SEFOS(config-vlan)# ip igmp snooping mrouter extreme-ethernet 0/2
       SEFOS(config-vlan)# exit

8. Enter the Interface Configuration mode for Gigabit Ethernet interface `0/1`.

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

9. Set the PVID as `VLAN 2`.

       SEFOS(config-if)# switchport pvid 2

10. Bring up the interface.

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

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

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

12. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

13. Bring up the interface.

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

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

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

15. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

16. Bring up the interface.

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

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

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

18. Set the PVID as `VLAN 2`.

        SEFOS(config-if)# switchport pvid 2

19. Bring up the interface.

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

20. Review the IGS-related configurations.

        SEFOS# show ip igmp snooping globals

        Snooping Configuration
        -----------------------------
        IGMP Snooping globally enabled
        IIGMP Snooping is operationally enabled
        IGMP Snooping Enhanced mode is disabled
        Transmit Query on Topology Change globally disabled
        Multicast forwarding mode is MAC based
        Proxy globally disabled
        Proxy reporting globally enabled
        Filter is disabled
        Router port purge interval is 125 seconds
        Port purge interval is 260 seconds
        Report forward interval is 5 seconds
        Group specific query interval is 2 seconds
        Reports are forwarded on router ports
        Group specific query retry count is 2
        Multicast VLAN disabled
        Leave config level is Vlan based

21. Review the database information for `VLAN 2`.

        SEFOS# show vlan id 2

        Vlan database-------------Vlan ID                 : 2Member Ports            : Ex0/1, Ex0/2, Ex0/3, Ex0/4Untagged Ports          : NoneForbidden Ports         : NoneName                    :Status                  : Permanent------------------------------------------------------------

22. Review the multicast router information.

        SEFOS# show ip igmp snooping mrouter

        Vlan   Ports
        ------   -------
            2    Ex0/2(static)

23. Send an IGMP V2 report from host B and host C.

    Only one of the reports should be forwarded to the router port on host A.
