5 packets transmitted
0 packets received
100.00% packet loss
If the displayed result shows that the IAD cannot receive the data package, the network
may be busy or disconnected.
3. You can set the -c parameter of ping command to adjust the sending packets.
For example, to send 10 packets for testing the network, run the following command:
TERMINAL>ping 172.21.50.51 -c 10
PING 172.21.50.51: 56 data bytes, press CTRL_C to break

10 packets transmitted
5 packets received /*5 packets are received.*/
50.00% packet loss /*Packet loss rate is 50%.*/
round-trip min/avg/max = 0/0/0 ms
In the preceding result, only five packets are received. The packet loss is severe. The
packet loss may be caused by bad connection quality between maintenance terminal 1
and the IAD, busy network, or interference.
3.6 Tracing Route
By running the tracert command, you can display all the gateways that a test data package
goes through from the sending host to the destination.
The example for running the tracert command is as follows:
Figure 3-8 shows the networking status.
