Using A Tracert Command To Identify Failed Or All Nodes In A Path; System Debugging; Debugging Information Control Switches - HP 6125G Configuration Manual

icmp-extensions compliant command on the devices. For more information about this command,
see Layer 3—IP Services Command Reference.
For an IPv6 network:
Enable sending of ICMPv6 timeout packets on the intermediate devices (the devices between the
•
source and destination devices). If the intermediate devices are HP devices, execute the ipv6
hoplimit-expires enable command on the devices. For more information about this command, see
Layer 3—IP Services Command Reference.
Enable sending of ICMPv6 destination unreachable packets on the destination device. If the
•
destination device is an HP device, execute the ipv6 unreachables enable command. For more
information about this command, see Layer 3—IP Services Command Reference.

path
Task
Display the routes from
source to destination.

System debugging

The device supports various debugging for the majority of protocols and features and provides
debugging information to help users diagnose errors.

Debugging information control switches

The following two switches control the display of debugging information:
Protocol debugging switch—Controls protocol-specific debugging information.
•
Screen output switch—Controls whether to display the debugging information on a certain screen.
•
As shown in
The debugging information can be output on a terminal only when both the protocol debugging switch
and the screen output switch are turned on.
Output of debugging information depends on the configurations of the information center and the
debugging commands of each protocol and functional module. Debugging information is typically
displayed on a terminal (including console or VTY) for display. You can also send debugging
information to other destinations. For more information, see "Configuring the information center."
Command
•
For an IPv4 network:
tracert [ -a source-ip | -f first-ttl | -m max-ttl |
-p port | -q packet-number | -tos tos |
-vpn-instance vpn-instance-name | -w
timeout ] * host
•
For an IPv6 network:
tracert ipv6 [ -f first-ttl | -m max-ttl | -p port |
-q packet-number | -tos tos | -w timeout ] *
host
Figure 3, assume that the device can provide debugging for the three modules 1, 2, and 3.
