Enable sending ICMP destination unreachable messages on the destination device. If the
destination device is an HPE device, use the
ip unreachables enable
command.
For more information about the
ip ttl-expires enable
and
ip unreachables enable
commands, see
Layer 3—IP Services Command Reference
.
The UDP tracert operation is not supported in IPv6 networks. To determine the routing path that the
IPv6 packets traverse from the source to the destination, use the
tracert ipv6
command. For more
information about the command, see
Network Management and Monitoring Command Reference.
To configure the UDP tracert operation:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an NQA operation
and enter NQA operation
view.
nqa entry admin-name
operation-tag
By default, no NQA operations exist.
3.
Specify the UDP tracert
operation type and enter its
view.
type
udp-tracert
N/A
4.
Specify the destination
device for the operation.
•
Specify the destination
device by its host name:
destination host
host-name
•
Specify the destination
device by its IP address:
destination ip
ip-address
By default, no destination IP
address or host name is specified.
5.
(Optional.) Specify the
destination port of UDP
packets.
destination port
port-number
By default, the destination port
number is 33434.
This port number must be an
unused number on the destination
device, so that the destination
device can reply with ICMP port
unreachable messages.
6.
(Optional.) Set the payload
size for each UDP packet.
data-size
size
The default setting is 100 bytes.
7.
(Optional.) Enable the
no-fragmentation feature.
no-fragment enable
By default, the no-fragmentation
feature is disabled.
8.
(Optional.) Set the maximum
number of consecutive probe
failures.
max-failure
times
The default setting is 5.
9.
(Optional.) Set the TTL value
for UDP packets in the start
round of the UDP tracert
operation.
init-ttl value
The default setting is 1.
10.
(Optional.) Specify an output
interface for UDP packets.
out interface interface-type
interface-number
By default, the output interface for
UDP packets is not specified. The
NQA client determines the output
interface based on the routing table
lookup.
11.
(Optional.) Specify the
source port of UDP packets.
source port port-number
By default, no source port number is
specified.
