42.1.8 Tech-Support
The Tech-Support feature is a log enhancement tool that logs useful information such as CPU
utilization history, memory and Mbuf (Memory Buffer) log and crash reports for issue analysis by
customer support should you have difficulty with your Switch. The Tech Support menu eases your
effort in obtaining reports and it is also available in CLI command by typing “Show tech-support”
command.
Click Menu > Management > Maintenance > Tech-Support to see the following screen.

LABEL DESCRIPTION
CPU Type a number ranging from 50 to 100 in the CPU threshold box, and type another
number ranging from 5 to 60 in the seconds box then click Apply.
For example, 80 for CPU threshold and 5 for seconds means a log will be created when
CPU utilization reaches over 80% and lasts for 5 seconds.
The log report holds 7 days of CPU log data and is stored in volatile memory (RAM). The
data is lost if the Switch is turned off or in event of power outage. After 7 days, the logs
wrap around and new ones replace the earliest ones.
The higher the CPU threshold number, the fewer logs will be created, and the less data
technical support will have to analyze and vice versa.
Mbuf Type a number ranging from 50 to 100 in the Mbuf (Memory Buffer) threshold box. The
Mbuf log report is stored in flash (permanent) memory.
For example, Mbuf 50 means a log will be created when the Mbuf utilization is over
50%.
The higher the Mbuf threshold number, the fewer logs will be created, and the less data
technical support will have to analyze and vice versa.
