54 Analysis. Typical tasks and solutions
5.12 Testing TCP/IP
All the tests described in the current section are required for testing through
routable networks. Using these tests, you can detect network configuration
problems, check server availability, check operability and estimate load of data
link.

allows to check availability of specified address inside or outside
of a subnet. Ping utility sends requests to the specified network host and
registers incoming responses. This procedure is based on the IP and ICMP
protocols of datagram transmission, and allows to check operability and mea-
sure load level of data links and intermediate devices.
Figure 5.54. Ping settings
•
Port — select a port to send requests from. If Automatic set, the port
will be selected automatically.
•
IP address — IP address of a network host to be tested for availability.
• Packet size — size of payload in transmitted frame, in bytes.
• Count — number of packets to be send (0–9999). If the null value
is selected, the ping test will be performed until button ( Stop ) is
pressed.
• Timeout — period of time to wait for response to a ping request (ms).
