WSS# traceroute server1

traceroute to server1.example.com (192.168.22.7), 30 hops max, 38 byte packets

1 engineering-1.example.com (192.168.192.206) 2 ms 1 ms 1 ms

2 engineering-2.example.com (192.168.196.204) 2 ms 3 ms 2 ms

3 gateway_a.example.com (192.168.1.201) 6 ms 3 ms 3 ms

4 server1.example.com (192.168.22.7) 3 ms * 2 ms

The first row of the display indicates the target host, the maximum number of hops, and the packet size. Each numbered

row displays information about one hop. The rows are displayed in the order in which the hops occur, beginning with the

hop closest to the WSS.

The row for a hop lists the total time in milliseconds for each ICMP packet to reach the router or host, plus the time for

the ICMP Time Exceeded message to return to the host.

An exclamation point (!) following any of these values indicates that the Port Unreachable message returned by the

destination has a maximum hop count of 0 or 1. This can occur if the destination uses the maximum hop count value

from the arriving packet as the maximum hop count in its ICMP reply. The reply does not arrive at the source until the

destination receives a traceroute packet with a maximum hop count equal to the number of hops between the source and

destination.

An asterisk (*) indicates that the timeout period expired before WSS Software received a Time Exceeded message for the

packet.

If Traceroute receives an ICMP error message other than a Time Exceeded or Port Unreachable message, WSS Software

displays one of the error codes described in Table 28 instead of displaying the round-trip time or an asterisk (*).

Table 28 describes the traceroute error messages.
