Mikrotik 1000u -setting up ether ports

In process of setting up new 1000U, have setup Ether 1 For Wan connection and Ether 2 for Hotspot. How do you setup Ports 3 & 4 as hotspot ports as well. Appreciate Help

try this

/ip hotspot
add address-pool=dhcp_pool3 addresses-per-mac=2 disabled=no idle-timeout=none \
    interface=ether4 keepalive-timeout=none name=server3 profile=hsprof1
add address-pool=dhcp_pool2 addresses-per-mac=2 disabled=no idle-timeout=none \
    interface=ether3 keepalive-timeout=none name=server2 profile=hsprof1
add address-pool=dhcp_pool1 addresses-per-mac=2 disabled=no idle-timeout=none \
    interface=ether2 keepalive-timeout=none name=server1 profile=hsprof1

Thankyou Eng, English is fine
