Execution Example
Displays network route.
Displays the route to the specified host (IP address or host name) by sending test
packets to the host with the time-to-live value in the IP datagram header set to 1 at first,
then incrementally increasing by 1, and analyzing the ICMP time exceeded packets and
ICMP destination unreachable packets received.
The meanings of the letter codes displayed by traceroute are listed below.
[Destination is an IPv4 address]
xx.xxx ms
: Round trip time
!N : Destination unreachable (no route to network)
!H : Destination unreachable (no route to host)
!P : Destination unreachable (protocol unreachable)
!F : Destination unreachable (fragment needed)
!S : Source route error
! : Abnormal TTL value
* : Probe timeout
[Destination is an IPv6 address]
xx.xxx ms
: Round trip time
!N : Destination unreachable (no route to network)
!H : Destination unreachable (no route to address)
!P : Destination unreachable (not a neighbor)
!F : Festination unreachable (administrative reason)
!S : Source route error
! : Abnormal HopLimit value
* : probe timeout
In addition, traceroute reports the following errors.
traceroute: unknown host <host_name>
Cannot resolve destination IP address for <host_name> specified.
traceroute: can't assign source address
Assignment of source IP address failed.
(In cases such as when the specified address does not exist for the switch.)
