Even with "no arp arpa" interface still process dynamic ARPA arp.

What's more:

interface FastEthernet0/0
 ip address
 speed auto
 no arp arpa

FastEthernet0/0 is up, line protocol is up 
  Hardware is PQUICC_FEC, address is 0007.8580.7e1b (bia 0007.8580.7e1b)
  Internet address is
  MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, 
     reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA, loopback not set
