CISCO 871 - Problem to configure VLAN

I have a router CISCO 871 (4 fe ports and 1 wan port) and I want to configure new VLANs. I have this configuration in my router:
...
!
interface FastEthernet0
!
interface FastEthernet1
!
interface FastEthernet2
!
interface FastEthernet3
!
interface FastEthernet4
 description $FW_OUTSIDE$$ES_WAN$$ETH-WAN$
 no ip address
 no ip redirects
 no ip proxy-arp
 ip route-cache flow
 duplex auto
 speed auto
 pppoe enable
 pppoe-client dial-pool-number 1
!
interface Vlan1
 description $ETH-SW-LAUNCH$$INTF-INFO-HWIC 4ESW$$ES_LAN$$FW_INSIDE$
 ip address 192.168.0.1 255.255.255.0
 ip access-group 100 in
 no ip redirects
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 ip route-cache flow
 ip tcp adjust-mss 1452
!
interface Vlan2
 ip address 192.168.100.1 255.255.255.0
 no ip redirects
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 ip route-cache flow
 ip tcp adjust-mss 1452
!

...

When I try to configure VLAN2 to fe2 I receive the following error:

router(config)#interface fastEthernet 2
router(config-if)#switchport access vlan 2
%Access VLAN 2 does not exist. Please add it to vlan database


When I try to add the vlan to database I receive the following error:

router#vlan database
router(vlan)#vlan 2 state active
Vlan can not be added. Maximum number of 1 vlan(s) in the database.

or

router(vlan)#vlan 2 media ethernet name VLAN02
Vlan can not be added. Maximum number of 1 vlan(s) in the database.

The router CISCO 871 supports 4 VLANs and I don't know where I'm making the mistake!

This is another configuration I have in my router in vlan:


router(vlan)#sh
  VLAN ISL Id: 1
    Name: default
    Media Type: Ethernet
    VLAN 802.10 Id: 100001
    State: Operational

    Media Type: FDDI Net
    VLAN 802.10 Id: 101004
    State: Operational
