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 and 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.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top navigation
panel to save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.

Crash Click Download to see the crash log report. The log will include information of the last
crash and is stored in flash memory.
CPU history Click Download to see the CPU history log report. The 7-days log is stored in RAM and
you will need to save it, otherwise it will be lost when the Switch is shutdown or during
power outage.

memory.
