View IGMP Information for Layer 2 VSN Multicast

Use the following commands to display IGMP information.

Procedure

  1. Enter Privileged EXEC mode:

    enable

  2. Display information about the interfaces where IGMP is enabled:

    show ip igmp interface [gigabitethernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}][vlan <1-4059>[vrf WORD<1–16>][vrfids WORD<0–512>]

    Ensure that the output displays snoop-spb under MODE.

  3. Display information about the IGMP cache:

    show ip igmp cache [vrf WORD<1–16>][vrfids WORD<0–512>]

  4. Display information about the IGMP group:

    show ip igmp group [count][group {A.B.C.D}][member-subnet {A.B.C.D/X}] [vrf WORD<1–16>][vrfids WORD<0–512>]

  5. Display information about the IGMP sender:

    show ip igmp sender [count][group {A.B.C.D}][member-subnet {A.B.C.D/X}][vrf WORD<1–16>][vrfids WORD<0–512>]

  6. Display information about IGMP snoop-trace information:

    show ip igmp snoop-trace [group {A.B.C.D}][source {A.B.C.D}][vrf WORD<1–16>][vrfids WORD<0–512>]
