Pinging A Remote Device - RuggedCom RuggedSwitch RS1600 User Manual

Pinging A Remote Device

The ping command sends an ICMP echo request to a remotely connected device.
For each reply received the round trip time is displayed.
The ping command can be used to ensure connectivity to the next connected
device. The command "ping 192.168.0.1" will send a small number of pings to
this device and display the results.
The ping command is a useful tool for testing commissioned links. The command
also includes the ability to send a specific number of pings with specified time with
which to wait for a response.
The specification of a large number of pings and a short response time can
"flood" a link, stressing it more than a usual ping sequence. The command "ping
192.168.0.1 500 2" can be used to issue 500 pings each separated by 2 milliseconds
to the next switch. If the link used is of high quality then no pings should be lost
and the average round trip time should be small.
Note:
The device to be pinged must support ICMP echo.
Upon commencing the ping an ARP request for the MAC address of the device is issued.
If the device is not on the same network as the switch the default gateway must be programmed.
