Secure Core Technology (SCT)

One method of resisting DoS attacks employed by the switch is the use of SCT. SCT is enabled by default on the switch and cannot be disabled.

The Cisco device is an advanced device that handles management traffic, protocol traffic and snooping traffic, in addition to end-user (TCP) traffic. SCT ensures that the switch receives and processes management and protocol traffic, no matter how much total traffic is received. This is done by rate-limiting TCP traffic to the CPU.

There are no interactions with other features.

SCT can be monitored on the Security > Denial of Service > Security Suite Settings page (by clicking the Details button).
