eigrp authentication

someone please explain what I'm doing wrong, see output below. everytime I
give the interface level command ip authentication key-chain eigrp 100 eigrp
it erases my ip authentication mode eigrp 100 md5, and it's like I didn't
enter the commands. This has to be something stupid.

Thanks in advance

interface FastEthernet0/5
 no switchport
 ip address 148.1.57.7 255.255.255.0
end

SW1(config-if)#ip authen mode eigrp 100 md5
SW1(config-if)#do sh run int f0/5
