Question about configurations on Cisco router 3925

Dear zealots, I am configuring Routers and Switch to mitigate DDoS attacks, following this article: http://www.infosecwriters.com/Papers/HChau_Cisco-DoS-DDoS.pdf

However, when I enter "no ip directed-broadcast" into Router and Switch's interface mode, then it cannot be displayed when I hit "show run". Do you know why? My devices' version is 12.2 (Switch 3750/3560) and 15.1 (Router 3925)

And should I apply this command on VLAN interfaces in Switches?

R2#sh run | i version

ip ssh version 2

R1#sh run | i version
version 15.2
ip ssh version 2

Even on these routers, I could run "no ip directed-broadcast" on interface config mode, but could not find them in "show run'' 's result. Do you know why?
