6.7 Testing the Radio Link Quality Using the File Get Command
You can run a simple File Get test to verify the performance and integrity of the
communications between the CCU and EUM. The file get command prints and updates a
transfer rate in kbps for every 20 packets for image, config, and null files received to RAM
before being written to flash memory. Retrieving the file “null” using FTP results in a 2 MB file
of uninitialized characters.
The File Get test tests only the radio link, eliminating any problems due to the Ethernet side or
customer computer. The following procedure explains how to run the File Get test from the
EUM; however, you can also run the same test from the CCU, and the results will be equally
valid.
The FTP session will timeout after 60 seconds without a response, or the operator can
terminate the session.
To Test Radio Link Quality Using File Get Throughput Test
1. At the EUM, use the stats clear command to reset all statistics.
60:03:3a> statistics clear
2. At the CCU, use the watch <eum_id> command to begin gathering watch statistics
for the EUM. (For more information about the
watch command, refer to CCU Watch
Statistics
on page 298.)
60:03:3a> watch 60:ff:fe

3. At the EUM, type file get <ccu_ip_address>, and press Enter.
