Using PING To Test Connections
The PING (Packet InterNet Groper) program checks for a valid
connection to a network device. Any device with an IP address
can respond to a PING session. It tests network connections by
sending packets to a specified IP address and checking the
response.
If you have just set up address information for the bridge, reset
the bridge to save the information and for it to take effect.
We recommend that you PING the LinkBuilder MSH Management
Module, in the same chassis as the bridge, to test that PING is
working correctly.
You could use PING if:
You can't connect to a remote device and are unsure if it is
working.
There is a problem on the network and you need to check all the
nodes for response quickly.
If you get no response from a device, it could be because:
You are using the wrong IP address.
No one has assigned the IP address to the remote device or, if a
host name was used, the host name is not assigned to that IP
address in the bridge's host table. You may wish to contact
someone at the remote site.
The host is shut off or has crashed. You may wish to contact
someone at the remote site.
Your subnet mask is wrong.
The default gateway is wrong.
You have not assigned an IP address to the bridge.
