To determine whether a remote node is reachable, run an Echo test:
Specify the remote node address in the Host Name field.
Specify the number of seconds between each transmission in the Seconds to Pause between pings field.
Specify the packet size to be transmitted in the IP Packet Size to send in Bytes field.
Press Esc to begin transmitting.
If you receive an echo reply packet, the remote node is reachable.
