I don't know if this would affect it, but for completeness' sake, I'd
change several there, to have
BOOTPROTO=static
and put in the MAC address.

Have you checked with ifconfig to make sure that the correct NIC is
addressed as eth1? If this is CentOS 6, you need to also check
/etc/udev/rules.d/70-persistant-net.rules
