Excessive traffic burdens the CPU, and might prevent normal device operation.
The device uses the Secure Core Technology (SCT) feature to ensure that the
device receives and processes management and protocol traffic, no matter how
much total traffic is received
. SCT is enabled by default on the device and cannot
be disabled.
There are no interactions with other features.
To display CPU utilization:
STEP 1 Click Administration > Diagnostics > CPU Utilization.
The CPU Utilization page appears.
The CPU Input Rate field displays the rate of input frames to the CPU per second.
The window contains a graph of the CPU utilization. The Y axis is percentage of
usage, and the X axis is the sample number.
STEP 2 Select the Refresh Rate (time period in seconds) that passes before the statistics
are refreshed. A new sample is created for each time period
