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.

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

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

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.

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.
