Here is your answer from this web page, http://www.cisco.com/warp/customer/770/land-pub.shtml Planned and Available Catalyst 5xxx and 29xx Fixes A software fix has been developed for the Catalyst 5xxx and 29xx switch software. Because the impact of land.c attack on these switches is severe, and because the available configuration workarounds are not practical for many customers, Cisco has produced interim software builds incorporating these fixes. Two interim versions are available: 2.1(1102) and 2.4(401). Interim versions receive less testing than regular software releases, and Cisco's support resources for interim versions are more limited than support resources for regular releases. We ask that customers install these releases only if they believe their networks are at genuine risk of disruptive attack. Customers may obtain the interim software by contacting the Cisco TAC at +1 800 553 24HR. The fix will be incorporated in the next regularly scheduled maintenance releases of both 2.1 and 2.4 Catalyst 5xxx and 29xx software. -ben
