Note that secondary address is not the same as subinterface.
You can have lots of secondary addresses without involving subinterfaces.
If you want an Ethernet subinterface, corresponding to an ISL or 802.1q
VLAN tag, you need to define the VLAN encapsulation before addding an IP
address, eg:
interface fastethernet0.2
encapsulation isl 2
ip address 192.168.2.1 255.255.255.0
interface fastethernet0.3
encapsulation isl 3
ip address 192.168.3.1 255.255.255.0
