Troubleshooting Network Connections
Testing Throughput with TTCP
CLI Maintenance Guide 7-9
When the test ends, the CLI shows the results in a one-line report. For example, the
following command runs a test to the station at 192.168.98.55:
bstnA6k# expect ttcp transmit 192.168.98.55
Starting 10 second TCP transmit test. Hit ^C to abort...
1003.0552 MB / 10.00 sec = 841.3741 Mbps 9 %TX
bstnA6k#
The %TX field at the end of the output is the percent-CPU used by the SCM
processor.
Cancelling a TTCP Transmission
For cases where a connection error is causing the transmit to hang (for example, if
TTCP is not configured at the server), use <Ctrl-C> to cancel the test. For example,
bstnA6k# expect ttcp transmit 192.168.97.55
Starting 10 second TCP transmit test. Hit ^C to abort... <Ctrl-C>
bstnA6k#
Testing a RON Tunnel
To test the RON connection from one ARX to another, run
expect ttcp server
at the
receiving switch and then
expect ttcp transmit
from the sending switch. (For
information on creating a RON tunnel, refer back to “Creating a Tunnel to Another
ARX” on page 5-2 of the CLI Network-Management Guide .) Like the previous
expect
commands, you run
expect ttcp server
from any mode:
expect ttcp server
The CLI stops to wait for a TTCP transmission from another switch. The CLI remains
blocked until you press <Ctrl-C> to stop waiting. For example, the following
command waits for a TTCP transmission on the switch, “prtlndA1k:”
prtlndA1k# expect ttcp server
Waiting for TTCP client. Hit ^C to abort...
