Denial of Service
Use the Denial of Service (DoS) page to configure DoS control. The GS748T Smart Switch
provide support for classifying and blocking specific types of DoS attacks. The type of DoS
attacks the switch can detect and prevent are described in DoS Configuration on
page 45.
Auto-DoS Configuration
The Auto-DoS Configuration page lets you automatically enable all the DoS features available
on the switch, except for TCP and UDP port attacks. See DoS Configuration on
page 45 for
information about the types of DoS att
acks the switch can monitor and block.
Note: When Auto-DoS is enabled, a port that is under attack is
automatically shut down and does not forward traffic. The port can
be enabled only manually by the admin user. A warning message is
logged to the buffered log and is sent to the Syslog server.
To access the Auto-DoS Configuration page, click System  Management  Denial of
