If the device does not display the complete path
to the destination host, one of the following explanations might apply:
- The host is not operational.
- There are network connectivity problems between the device and
the host.
- The host, or a router along the path, might be configured
to ignore ICMP traceroute messages.
- The host, or a router along the path, might be configured
with a firewall filter that blocks ICMP traceroute requests or ICMP
time exceeded responses.
- The value you selected in the Time Exceeded box was less
than the number of hops in the path to the host. In this case, the
host might reply with an ICMP error message.
For more information about ICMP, see RFC 792, Internet Control Message Protocol.
