Using ping, tracert, and system debugging

This chapter covers ping, tracert, and information about debugging the system.

Ping

Use the ping utility to determine if an address is reachable.
Ping sends ICMP echo requests (ECHO-REQUEST) to the destination device. Upon receiving the requests,
the destination device responds with ICMP echo replies (ECHO-REPLY) to the source device. The source
device outputs statistics about the ping operation, including the number of packets sent, number of echo
replies received, and the round-trip time. You can measure the network performance by analyzing these
statistics.

Using a ping command to test network connectivity

Execute ping commands in any view.
Task
Determine if an address in an IP network is
reachable.
For more information about the ping mpls command, see MPLS Command Reference.

Ping example

Network requirements
As shown in
other, get detailed information about routes from Device A to Device C.
Figure 1, determine if Device A and Device C can reach each other. If they can reach each
Command
When you configure the ping command for a low-speed
network, set a larger value for the timeout timer (indicated by the
-t keyword in the command).
