Viewing IGMP snoop forwarding data

When IGMP snooping is enabled, IP multicast packets are forwarded to IGMP group members and router ports instead of flooding the entire VLAN. The Snoop Forwarding tab displays how many IP multicast forwarding destinations are in the table and the corresponding forwarding port list.

To display the current IGMP snooping forwarding table:

  1. From the Device Manager menu bar, choose IP Routing > IGMP.
  2. The IGMPSnoop dialog box opens with the Snoop Globals tab displayed.
  3. Click the Snoop Forwarding tab.
  4. The Snoop Forwarding tab opens.

The following table explains the fields in the Snoop Forwarding tab.


Field Description
Vid
Identifies the VLAN ID of the VLAN on which the router port resides.
GroupIPAddr
Identifies the group IP address learned from the IGMP packet, on a per VLAN basis.
