For the detailed description on the terminaldebugging and terminal monitor commands, refer to Information Center Commands in the SystemVolume.Ping and Tracert Configuration ExampleNetwork requirementsAs shown in Figure 1-4, Device A failed to telnet Device C. Now it is required to determine whether anavailable route exists between Device A and Device C. If no such a route exists, you need to locate thefailed nodes in the network.Figure 1-4 Ping and tracert network diagramConfiguration procedure# Use the ping command to display whether an available route exists between Device A and Device C. ping 1.1.2.2PING 1.1.2.2: 56 data bytes, press CTRL_C to breakRequest time outRequest time outRequest time outRequest time outRequest time out--- 1.1.2.2 ping statistics ---5 packet(s) transmitted0 packet(s) received100.00% packet loss# No such a route exists.
