I want to have static ip

so i changed /etc/network/interfaces

# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback

# Wireless interfaces
iface wlan0 inet dhcp
        wireless_mode managed
        wireless_essid any
        wpa-driver wext
        wpa-conf /etc/wpa_supplicant.conf

iface atml0 inet dhcp

# Wired or wireless interfaces
auto eth0
iface eth0 inet static
        address 192.168.2.8
        netmask 255.255.255.0
        network 192.168.2.254
        gateway 192.168.2.1
iface eth1 inet dhcp

# Ethernet/RNDIS gadget (g_ether)
# ... or on host side, usbnet and random hwaddr
iface usb0 inet static
        address 192.168.7.2
        netmask 255.255.255.0
        network 192.168.7.0
        gateway 192.168.7.1

# Bluetooth networking
iface bnep0 inet dhcp

do ifdown eth0
ifup eth0

and I can connect to static ip

after reboot there is no connection to the static ip possible and a new dynamic ip is taken via dhcp.

i do ifdown and ifup again. now i can connect via ssh to static and the dynamic ip.

that is normal?
