YMBOLS
The Trace Route feature allows you to display the network hops from the
Webcache to a device on an IP network.
A symbol may be displayed after a network hop which provides further
information about that hop. The symbol may indicate systems that are
unwilling to participate in a traceroute, or a problem with the system
concerned.
The symbols and their meanings are shown in
Table 22
.
Example
2.router1 (192.168.1.255) 26.027ms !H, 27.156ms!H,44.902ms !H
In this example,
!H
is displayed after every network hop for the system
router1
, indicating that the system is unreachable.
For further information about the Trace Route feature, see
“Performing a
Trace Route”
on
page 229
