If you are not able to <ping> the EUM from the PC, go to
Testing the Data Link from the End-user's PC to the Network
Once the connection from the PC to the EUM is confirmed, ping the EUM gateway address
from a PC DOS window. Ping with short packets first to confirm function, and then with long
packets (1472 byte packets) to confirm performance. Errors observed on pings with long
packets indicate a high error rate on the channel, caused by low signal levels or interference.
To Ping a CCU with the maximum packet size
1. Open a DOS window.
2. At the command prompt, type ping <aaa.bbb.ccc.ddd> -t -L 1472, where
<aaa.bbb.ccc.ddd> is the CCU radio IP address and press Enter.
3. Press Ctrl+c to end the test.
NOTE: If this test fails, but pinging the CCU with the default packet size
This following example uses the sample configuration shown in
Pinging the CCU from the end-user's PC (with maximum packet size):
C:\>ping 10.5.0.1 -t -l 1472
