View Layer 2 Tracetree Results

Use this procedure to view Layer 2 Tracetree results. The Layer 2 Tracetree command is a proprietary command that allows a user to trigger a multicast LTM message by specifying the B-VLAN and I-SID. This command allows the user to view a multicast tree on the SPBM B-VLAN from the source node to the destination nodes for a particular I-SID.

Note

Troubleshooting using ping and traceroute is not supported on EDM. For more information, see VOSS Release Notes. As an alternative, use CLI.

Procedure

In the navigation pane, expand Configuration > Serviceability > Diagnostics.
Select L2Ping/L2Trace Route.
Select the L2 Traceroute/TraceTree tab.
In the IsTraceTree field double-click and select true for EDM to perform Tracetree on the multicast tree.
Select Apply.
Select Refresh to update the results.
To view the tracetree results, highlight an entry, and then select Result.
