It's related to the internal path the packet takes through the router. This
state shows there are no features (acl, nat etc) configured. Configuring a
feature on the interfaces should change the ouput to Feature Fast turbo
vector.
interface FastEthernet0/0
ip address 10.0.0.1 255.255.255.0
speed 100
full-duplex
end
IP fast switching is enabled
IP fast switching on the same interface is disabled
IP Flow switching is disabled
IP CEF switching is enabled
IP CEF Fast switching turbo vector
Lewis#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Lewis(config)#int fa0/0
Lewis(config-if)#ip access
Lewis(config-if)#ip access-group 121 in
Lewis(config-if)#
IP fast switching is enabled
IP fast switching on the same interface is disabled
IP Flow switching is disabled
IP CEF switching is enabled
IP CEF Feature Fast switching turbo vector
Feature path is slightly slower. Nothing to be concerned about :-)
HTH, Rich
