8-6 Troubleshooting
This error occurs when there is heavy network traffic and the Traffic
Analyzer tool is not fast enough to analyze all the frames for the
triggers and pre-filters. You can use several methods to solve this error
condition:
•
dedicate your computer to the ControlNet Traffic Analyzer tool
(no background tasks running)
•
use a faster computer
•
reduce the amount of traffic seen by your computer through
defined trigger and pre-filter conditions. Reduce the amount of
traffic by disabling the following MAC frame status or types:
•
Null
•
Scheduled
•
Unscheduled
•
Moderator
The hardware passes through all traffic as enabled by the start, stop,
and pre-filter conditions in the Traffic Analyzer Control Panel settings.
When the start trigger is defined as “Start Always” and the stop trigger
is defined as “No Stop Condition,” then the traffic seen by the software
is only defined by the pre-filter.
Refer to the two examples on page 8-3 for clarification.
After you click on Continue in the warning box, the error message
displays in the exact frame in which the error occurred. Therefore, this
error message can appear several times in MAC Frame Data view.
TIP
You can combine the methods to solve this error condition.
TIP
For post-filter conditions, error frames are always displayed in
MAC Frame Data view. To display only error frames, create a
post-filter (click on the Filter on Conditions radio button)
without conditions (the top list must be empty) and apply the
filter.
