NOTE: Output Packets and Octets (from the CCU's perspective have
increased by 2 MB after the file get command from the EUM.
6.8 Testing End-to-End Throughput
The procedures outlined below will get a file from the CCU, and then put a file onto the CCU.
In both cases, you can record the file transfer performance. WaveRider recommends doing
this procedure with a screen capture, so you have a permanent record to baseline the
performance of the link.
Before you carry out the FTP test, you may want to baseline the performance of the computer
you are using at the EUM, by first connecting it directly to an FTP server and running an FTP
test back-to-back with the server. This back-to-back FTP test should be at least 3 Mbps, or
you may have a problem with your server or computer setup.
NOTE: The EUM can be used as an FTP server, provided the PC is on
the same subnet as the EUM or appropriate routes have been
added to the gateway router.
Entering
null as the destination filename in the put command ensures the file will not be
permanently stored to CCU memory. If you inadvertently forget to enter
null at the end of the
put command, and consequently save the file to memory, the measured throughput will be
lower than expected. You can remove the file using the CCU file services, available through
the command line interface. As long as you enter
null after the put command, any size file
can be used.
The FTP throughput should correspond to a value near the maximum allowed by the GOS,
assuming no other traffic is being carried by the CCU.
To Test End-to-End Throughput Using FTP
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 a PC connected to the EUM, open a console window and type ftp
<aaa.bbb.ccc.ddd>
, where <aaa.bbb.ccc.ddd> is the CCU Ethernet IP address.
4. In the FTP window, enter the following commands to
get a null file from the CCU:
Connected to <aaa.bbb.ccc.ddd>.
