Finding Feature Information - Cisco Catalyst 2960 series Configuration Manual

ACL Support for Filtering IP Options
The ACL Support for Filtering IP Options feature describes how to use an IP access list to filter IP packets
that contain IP options to prevent devices from becoming saturated with spurious packets.
This module also describes the ACL TCP Flags Filtering feature and how to use an IP access list to filter IP
packets that contain TCP flags. The ACL TCP Flags Filtering feature allows you to select any combination
of flags on which to filter. The ability to match on a flag set and on a flag not set gives you a greater degree
of control for filtering on TCP flags, thus enhancing security.
