Ping
P
ing is a utility used to test if a remote host can be reached and to measure the round-trip time for
packets sent from the device to a destination device.
Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the
target host and waiting for an ICMP response, sometimes called a pong. It measures the round-
trip time and records any packet loss.
To ping a host:
1. Click Maintenance > Diagnostics > Ping.
