11.2.1.3.15. Defining Denial Of Service Page
Configurable Data
Denial of Service SIP=DIP - Enable or disable this option by selecting the corresponding
line on the pulldown entry field. Enabling SIP=DIP DoS prevention causes the switch to
drop packets that have a source IP address equal to the destination IP address. The
factory default is disabled.
Denial of Service First Fragment - Enable or disable this option by selecting the
corresponding line on the pulldown entry field. Enabling First Fragment DoS prevention
causes the switch to drop packets that have a TCP header smaller then the configured Min
TCP Hdr Size. The factory default is disabled.
Denial of Service Min TCP Hdr Size - Specify the Min TCP Hdr Size allowed. If First
Fragment DoS prevention is enabled, the switch will drop packets that have a TCP header
smaller then this configured Min TCP Hdr Size. The factory default is disabled.
Denial of Service TCP Fragment - Enable or disable this option by selecting the
corresponding line on the pulldown entry field. Enabling TCP Fragment DoS prevention
causes the switch to drop packets that have an IP fragment offset equal to 1. The factory
default is disabled.
