Intel SBCEGBESW10 CLI manual Probe timed out

System Management Commands

The traceroute command sends out one probe at a time. Each outgoing packet may result in one or two error messages. A "time exceeded" error message indicates that an intermediate device has seen and discarded the probe. A "destination unreachable" error message indicates that the destination node has received the probe and discarded it because it could not deliver the packet. If the timer goes off before a response comes in, the

traceroute command prints an asterisk (*).

The traceroute command terminates when the destination responds, when the maximum TTL is exceeded or when the user interrupts the trace by pressing Esc.

Example

The following example discovers the routes that packets will actually take when traveling to their destination.

Console> traceroute umaxp1.physics.lsa.umich.edu
Type Esc to abort.

The following table describes significant fields shown above.

Field	Description
1	Indicates the sequence number of the device in the path to the host.
i2-gateway.stanford.edu	Host name of this device.
192.68.191.83	IP address of this device.
1 msec 1 msec 1 msec	Round-trip time for each probe sent.

The following table describes characters that may appear in the traceroute command output.

Field	Description
*	The probe timed out.
?	Unknown packet type.
A	Administratively unreachable. Usually, this output indicates that an access list is
	blocking traffic.
F	Fragmentation is required and DF is set.
