Ping -
This diagnostic tool troubleshoots connectivity, reachability, and name resolution to a
given host or gateway.
Traceroute -
This diagnostic tool tests the performance of a connection.
Note:
You can use ping / traceroute to test both numeric IP address or domain
name. If pinging / tracerouting the IP address is successful, but pinging /
tracerouting the domain name is not, you might have a name resolution problem.
In this case, ensure that the domain name you are specifying can be resolved by
using Domain Name System (DNS) queries.
IP Address/Domain Name -
Type the destination IP address (such as 192.168.40.1) or Domain
name (such as Legrand).
Pings Count -
The number of Ping packets for a Ping connection.
Ping Packet Size -
The size of Ping packet.
Ping Timeout -
Set the waiting time for the reply of each Ping packet. If there is no reply in the
specified time, the connection is overtime.
