Using ping and tracert
Ping
About ping
Use the ping utility to determine if an address is reachable.
Ping sends ICMP echo requests (ECHO-REQUEST) to the destination device. Upon receiving the
requests, the destination device responds with ICMP echo replies (ECHO-REPLY) to the source
device. The source device outputs statistics about the ping operation, including the number of
packets sent, number of echo replies received, and the round-trip time. You can measure the
network performance by analyzing these statistics.
You can use the ping –r command to display the routers through which ICMP echo requests have
passed. The test procedure of ping –r is as shown in Figure 1:
1. The source device (Device A) sends an ICMP echo request to the destination device (Device C)
with the RR option empty.
2. The intermediate device (Device B) adds the IP address of its outbound interface (1.1.2.1) to
the RR option of the ICMP echo request, and forwards the packet.
3. Upon receiving the request, the destination device copies the RR option in the request and
adds the IP address of its outbound interface (1.1.2.2) to the RR option. Then the destination
device sends an ICMP echo reply.
4. The intermediate device adds the IP address of its outbound interface (1.1.1.2) to the RR option
in the ICMP echo reply, and then forwards the reply.
5. Upon receiving the reply, the source device adds the IP address of its inbound interface (1.1.1.1)
to the RR option. The detailed information of routes from Device A to Device C is formatted as:
1.1.1.1 <-> {1.1.1.2; 1.1.2.1} <-> 1.1.2.2.
Figure 1 Ping operation

The output shows the following information:
•
Device A sends five ICMP packets to Device C and Device A receives five ICMP packets.
•
No ICMP packet is lost.
•
The route is reachable.
Tracert
About tracert
Tracert (also called Traceroute) enables retrieval of the IP addresses of Layer 3 devices in the path
to a destination. In the event of network failure, use tracert to test network connectivity and identify
failed nodes.
Device A Device B Device C
1.1.1.1/24 1.1.1.2/24 1.1.2.1/24 1.1.2.2/24
3
Figure 3 Tracert operation
Tracert uses received ICMP error messages to get the IP addresses of devices. Tracert works as
shown in Figure 3:
1. The source device sends a UDP packet with a TTL value of 1 to the destination device. The
destination UDP port is not used by any application on the destination device.
2. The first hop (Device B, the first Layer 3 device that receives the packet) responds by sending a
TTL-expired ICMP error message to the source, with its IP address (1.1.1.2) encapsulated. This
way, the source device can get the address of the first Layer 3 device (1.1.1.2).
3. The source device sends a packet with a TTL value of 2 to the destination device.
4. The second hop (Device C) responds with a TTL-expired ICMP error message, which gives the
source device the address of the second Layer 3 device (1.1.2.2).
5. This process continues until a packet sent by the source device reaches the ultimate
destination device. Because no application uses the destination port specified in the packet, the
destination device responds with a port-unreachable ICMP message to the source device, with
its IP address encapsulated. This way, the source device gets the IP address of the destination
device (1.1.3.2).
6. The source device determines that:
The packet has reached the destination device after receiving the port-unreachable ICMP
message.
The path to the destination device is 1.1.1.2 to 1.1.2.2 to 1.1.3.2.
Prerequisites
Before you use a tracert command, perform the tasks in this section.
IPv4:
•
Enable sending of ICMP timeout packets on the intermediate devices (devices between the
source and destination devices). If the intermediate devices are HPE devices, execute the ip
ttl-expires enable command on the devices.
•
Enable sending of ICMP destination unreachable packets on the destination device. If the
destination device is an HPE device, execute the ip unreachables enable command.
For more information about the ip ttl-expires enable and ip unreachables enable
commands, see IP performance optimization commands in Layer 3—IP Services Command
Reference.

•
Enable sending of ICMPv6 timeout packets on the intermediate devices (devices between the
source and destination devices). If the intermediate devices are HPE devices, execute the
ipv6 hoplimit-expires enable command on the devices.
•
Enable sending of ICMPv6 destination unreachable packets on the destination device. If the
destination device is an HPE device, execute the ipv6 unreachables enable command.
For more information about the ipv6 hoplimit-expires enable and ipv6 unreachables
enable commands, see IPv6 basics commands in Layer 3—IP Services Command Reference.
Using a tracert command to identify failed or all nodes in a
path

The output shows that Device A can reach Device B but cannot reach Device C. An error has
occurred on the connection between Device B and Device C.
5. To identify the cause of the issue, execute the following commands on Device A and Device C:
Execute the debugging ip icmp command and verify that Device A and Device C can
send and receive the correct ICMP packets.
Execute the display ip routing-table command to verify that Device A and Device
C have a route to each other.

Configuring system debugging
About system debugging
The device supports debugging for the majority of protocols and features, and provides debugging
information to help users diagnose errors.
The following switches control the display of debugging information:
•
Module debugging switch—Controls whether to generate the module-specific debugging
information.
•
Screen output switch—Controls whether to display the debugging information on a certain
screen. Use terminal monitor and terminal logging level commands to turn on
the screen output switch. For more information about these two commands, see information
center commands in System Management Command Reference.
As shown in Figure 5, 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 module debugging switch and
the screen output switch are turned on.
Debugging information is typically displayed on a console. You can also send debugging information
to other destinations. For more information, see information center configuration in System
Management Configuration Guide.
Figure 5 Relationship between the module and screen output switch
Debugging a feature module
Restrictions and guidelines
CAUTION:
Output of excessive debugging messages increases the CPU usage and downgrades the system
performance.
To guarantee system performance, enable debugging only for modules that are in an
exceptional condition.

Configuring NQA
About NQA
Network quality analyzer (NQA) allows you to measure network performance, verify the service
levels for IP services and applications, and troubleshoot network problems.
NQA operating mechanism
An NQA operation contains a set of parameters such as the operation type, destination IP address,
and port number to define how the operation is performed. Each NQA operation is identified by the
combination of the administrator name and the operation tag. You can configure the NQA client to
run the operations at scheduled time periods.
As shown in Figure 6, the NQA source device (NQA client) sends data to the NQA destination device
by simulating IP services and applications to measure network performance.
All types of NQA operations require the NQA client, but only the TCP and UDP echo operations
require the NQA server. The NQA operations for services that are already provided by the destination
device such as FTP do not need the NQA server. You can configure the NQA server to listen and
respond to specific IP addresses and ports to meet various test needs.
Figure 6 Network diagram
After starting an NQA operation, the NQA client periodically performs the operation at the interval
specified by using the frequency command.
You can set the number of probes the NQA client performs in an operation by using the probe
count command.
Collaboration with Track
NQA can collaborate with the Track module to notify application modules of state or performance
changes so that the application modules can take predefined actions.
The NQA + Track collaboration is available for the following application modules:
•
VRRP.
•
Static routing.
•
Policy-based routing.
•
Smart Link.
The following describes how a static route destined for 192.168.0.88 is monitored through
collaboration:
1. NQA monitors the reachability to 192.168.0.88.
2. When 192.168.0.88 becomes unreachable, NQA notifies the Track module of the change.
3. The Track module notifies the static routing module of the state change.
4. The static routing module sets the static route to invalid according to a predefined action.
