    Traceroute from Device to Device

    The traceroute utility traces the route of an IP packet from one device to another.

    1. Select Tools > Diagnostics > Trace Route.
    2. Move your cursor to the topology map and you will notice that it has become a cross-hair. Click on the router you want to trace from, then click on the router you want to trace to, or select “Enter destination IP address” to enter in a specific destination IP address.
