have an active remote device attached, then first bring down the ports which do not have active connections expected to make sure there is a legitimate EXT FLT condition.

If loss of communications is suspected on an externally wired port, make sure to check and test affected cables.

Network Tests

Ping Test

It is possible to test a network connection by using the ping command. The ping command will send a network packet to the specified IP address and wait for a reply.

To initiate a ping test, type

ping <ip address>

If you have a network connection, a normal output would look like the following:

sh-2.04# ping 10.0.0.43
