Troubleshooting DVMRP

The Mroute-HW tab provides an exact hardware view of existing IP multicast records and information on sender and receiver ports for every stream. When you select this tab, you are presented with a table and three additional tabs (Prunes, Sources, and EgressVLANs) that allow you to gather additional information on multicast hardware records. This section describes these new tabs and explains how to access them.

To perform DVMRP troubleshooting:

  1. From the Device Manager menu bar, choose IP Routing > Multicast.
    2. The Multicast dialog box opens with the Routes tab displayed.
  2. Click the Mroute-HW tab.
    3. The Mroute-HW tab opens.
    By default, all three buttons (Prunes, Sources, and EgressVLANs) in the dialog are disabled.
  3. Click on any row in the table (representing the output of Mroute-HW).
    4. The Prunes, Sources, and EgressVLANs buttons are enabled (highlighted).
  4. Click either the Prunes, Sources, or Egress Vlans buttons.
    5. Depending on your selection, the Prunes, Sources, or Egress VLANs dialog box will open displaying further information about the stream selected in the table.
  5. Click the Close button to return to the Multicast- Mroute-HW tab.
