Viewing CPU Utilization and Secure Core Technology
This section describes the Secure Core Technology (SCT) and how to view CPU
usage.
The switch handles the following types of traffic, in addition to end-user traffic:
• Management traffic
• Protocol traffic
• Snooping traffic
Excessive traffic burdens the CPU, and might prevent normal switch operation.
The switch uses the Secure Core Technology (SCT) feature to ensure that the
switch will receive and process 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.
or
STEP 2 Click Security > Denial of Service Prevention > Security Suite Settings and click
