then do a “service network restart”
DEVICE=eth1 ONBOOT=yes BOOTPROTO=static BROADCAST=10.1.255.255 <-- replace with own HWADDR=00:00:00:00:00:00 <-- replace with own MAC Address with your MAC Address IPADDR=10.1.0.123 <-- replace with own NETWORK=10.1.0.1 <-- replace with own gateway NETMASK=255.255.0.0 <-- replace with own network mask TYPE=Ethernet
DEVICE=eth1 ONBOOT=yes BOOTPROTO=static BROADCAST=10.1.255.255 HWADDR=00:00:00:00:00:00 IPADDR=10.1.0.123 GATEWAY=10.1.0.1 NETMASK=255.255.0.0 TYPE=Ethernet
