Using a tracert command to identify failed or all nodes in a
path
To execute tracert commands to identify failed or all nodes in a path:
Step Command Remarks
1. Enter system view. system-view N/A
2. Display the routes from source
to destination.
• For IPv4 networks:
tracert [ -a source-ip | -f first-ttl
| -m max-ttl | -p port | -q
packet-number | -w timeout ] *
host
• For IPv6 networks:
tracert ipv6 [ -f first-ttl | -m
max-ttl | -p port | -q
packet-number } | -w timeout ]
* host
Use either approach.
Available in any view.
System debugging
The device supports debugging for the majority of protocols and features, and provides debugging
information to help users diagnose errors.
Debugging information control switches
The following switches control the display of debugging information:
• Protocol debugging switch, which controls protocol-specific debugging information.
• Screen output switch, which controls whether to display the debugging information on a certain
screen.
Output of debugging information depends on the configurations of the information center and the
debugging commands of each protocol and functional module. Displaying the debugging information
on a terminal (including console or VTY) is a common way to output debugging information. You can
also output debugging information to other destinations. For more information, see "Configuring the
information center."
As shown in
Figure 3 , assume that the device can provide debugging for the three modules 1, 2, and 3.
The debugging information can be output on a terminal only when both the protocol debugging switch
and the screen output switch are turned on.
