7 Configuring Network Communication Test Tools
7.1 Overview
Network communication test tools can be used to check the connectivity of a network and helps you analyze and locate
network faults. Network communication test tools include Packet Internet Groper (PING) and Traceroute. Ping is used to
check the connectivity and delay of a network. A greater delay indicates a slower network speed. Traceroute helps you learn
about the topology of physical and logical links and transmission rate. On a network device, you can run the ping and
traceroute commands to use the two tools respectively.
Protocols and Standards
RFC792: Internet Control Message Protocol
RFC4443: Internet Control Message Protocol (ICMPv6) for the Internet Protocol Version 6 (IPv6) Specification
7.2 Applications
End-to-End Connectivity Test
Both the network device and the destination host are connected to the IP network and
configured with IP addresses.
Both the network device and the destination host are connected to the IP network and
configured with IP addresses.
7.2.1 End-to-End Connectivity Test
Scenario
As shown in Figure 7-1, Network Device A and Target Host B are connected to the IP network.
If both the network device and the target host are connected to the IP network, the end-to-end connectivity test aims to check
whether IP packets can be transmitted between the two ends. The target host can be the network device itself. In this case,
the connectivity test aims to check the network interface and TCP/IP configurations on the device.

Deployment
Execute the ping function on the network device.
