76 Using Features of US40a
Ping Diagnosis Utility
Command "Ping" executes the ping diagnosis utility and displays replied messages.
The diagnosis tool sends echo requests to the network host. The host parameter is the effective name
of the host or IP address. Operating on the network, the host replies the echo requests.
The ping diagnosis utility sends a single echo request every second, calculates the round trip time
and packet loss statistics and displays a simple summary after completing the calculations.
NOTE:
All network devices do not always reply to ping packets. It is
because Ping is a general feature used for denial-of-service attacks. No
response from a device targeted by Ping does not always indicate that
the device is unavailable for other purposes.
Ipconfig Utility
Command "Ipconfig" indicates the TCP/IP configuration.
NOTE:
You can check the MAC address of US40a in the normal
network interface in the following steps:
1. Open [Network Utilities] on the [Control Panel].
2. Select "Ipconfig" and execute it with option "/all". The MAC
address appears on the Physical Address line in the execution result.
netstat Utility
Command "netstat" indicates the status of TCP connection under communication.
