[c-nsp] 3750 12.2(25)SEE1 unicast rpf?

[Peter Gutierrez]

Is there a command on the 3750 to do anti-spoofing rpf checks on 
interfaces?

This doesn't work:

box1(config-if)#int gi 1/0/11
box1(config-if)# ip verify unicast source reachable-via rx
                               ^
% Invalid input detected at '^' marker.


Thanks.
