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.
