for what it's worth, my (working, for years) /etc/network/interfaces 
file looks like this:

auto lo eth0 eth0:1 eth0:2 eth0:3 eth0:4 eth0:5 eth0:6 eth0:7 eth0:8 
eth0:9 eth0
:10 eth0:11 eth0:12 eth0:13 eth0:14 eth0:15

iface eth0 inet static
    address 207.154.13.48
    netmask 255.255.255.224
    network 207.154.13.32
    broadcast 207.154.13.63
    gateway 207.154.13.33
    # dns-* options are implemented by the resolvconf package, if installed
    dns-nameservers 209.59.0.18 209.59.0.2
    dns-search neighborhoods.net

iface eth0:1 inet static
    address 207.154.13.49
    netmask 255.255.255.224
    broadcast 207.154.13.63

iface eth0:2 inet static
    address 207.154.13.50
    netmask 255.255.255.224
    broadcast 207.154.13.63

<etc>
