Logging Scenarios - ASCOM Myco 3 Troubleshooting Manual

TROUBLESHOOTING GUIDE
Ascom Myco 3
Requirements
To perform an air trace, the support engineer should be equipped with the following:
• A portable PC.
• Airtrace tool (Omnipeek is recommended). This is used to take wireless sniffer traces of:
− The AP that is transmitting.
− The handset that is transmitting.
− Other air traffic.
• When troubleshooting the roaming problems, either use one adapter per each channel set in the WLAN
system or redesign the system in a way to cover the troubleshooting area with the adapters you have.
If there is only one specific problem that is easy to reproduce, one WLAN adapter is sufficient.
• It is important to have the same time zone, timestamps, and date formats set on all the devices (PCs,
handsets, and etc.) that will be used for logging collection. Moreover, it is required to indicate your time
zone when sending the logs to be analyzed by the Ascom R&D.
If the time zone of logs is not determined, the logs will be stamped with the Ascom's local time. In this
case, the time zone might not coincide with the actual time zone thus significantly affecting the results of
the analysis.
• It is important to send for analysis simultaneous and time-synced logs collected from all the devices (PCs,
handsets, and etc.) that have been used for logging collection.

Logging Scenarios

There are different types of logging that can be used, depending on the area to be investigated. The
support engineer, in the first place, should investigate and rule out relatively easy to identify causes, such
as incorrectly configured parameters and incompatible software versions. If this is a case, RF problems,
should be investigated and eliminated as a cause of a problem through a site survey. If no relevant
information can be collected and the problem is persistent, logs should be collected.
Use the following references to get more details on the particular logs:
• 5.5 Event Logs (Log Viewer), page
• 5.6 Debug with Timed Logging, page
• 5.7 Debug Using PCAP , page
• 5.8 Debug Using Remote PCAP, page
• 5.3 Air Traces of 802.11 Traffic, page
Encrypted logs should be collected from the handset and sent to be analyzed by the Ascom R&D.
The below tables explain which logs should be collected in response to the area of the raised problem:
