Hi Kenneth,
The "ip verify" command is not supported on Cat3550 as documented in the
"Catalyst 3550 Multilayer Switch Software Configuration Guide" under
"Unsupported CLI Commands".
The "ip verify unicast [reverse-path|source]" command is officially removed
from 12.1(20)EA1 due to CSCec42543.
HTH,
Xiangrong
