Will traceroute show switches?
No. The hops shown by traceroute show the path that an IP packet follows on a routed (layer 3) network. Routers will show up, and switches will not. Switches are by their nature a layer 2 device: they receive and forward Ethernet frames, using the destination MAC address to determine the correct destination port.
How does traceroute work in detail?
Traceroute ensures each hop on the way to a destination device drops a packet and sends back an ICMP error message. This means traceroute can measure the duration of time between when the data is sent and when the ICMP message is received back for each hop—giving you the RTT value for each hop.
What does asterisks in a traceroute mean?
If a router doesn’t generate a Time-to-live exceeded response, traceroute will not know anything about that hop. A hop that outputs * * * means that the router at that hop doesn’t respond to the type of packet you were using for the traceroute (by default it’s UDP on Unix-like and ICMP on Windows).
How do you know if a traceroute fails?
Trace back to your source server and traceroute will probably fail at the bad router on the return path. If the trace fails – Test the routing table and check the other status of all the hops between this router and your target destination.

How is time to live calculated in traceroute?
By default, for Traceroute utility, the “time to live” value will be decremented by 1 each time packet passes through a router. However, is the “time to live” value also
