Dear All,
For your information. If the RHEL server setup within local area network. You may either configure each Network Interface card by:
1) Receiving IP address from nearest DHCP server appliance e.g network switches
2) Manual. By allocate exactly. Static IP address for each Network Interface card.
For manually configured static IP Address. You may refer the following command:
$ ifconfig eth0 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
$ ifconfig eth1 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
$ ifconfig eth2 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
where xxx = IPv4 static ip address
and yyy = IPV4 netmask ip address.

Subject: Re: Network interfaces not reachable
Hello,
Firtst of all, thanks a lot for your responses.
1. @Marco : I mean by 'not reachable' that nether my local network,
nether the internet can ping my network interfaces.
2. @Mark : I use RHEL 6, I will look in '70-persistant-net'.
3. @FrankCui : Here my network interfaces config :
*ETH0 : *
BOOTPROTO=none
BROADCAST={PUBLIC BROADCAST IP}
DEVICE=eth0
HWADDR=00:1B:21:30:48:1E
IPADDR={PUBLIC IP}

IPV6INIT=no
NETMASK=255.255.255.224
NETWORK={PUBLIC NETWORK IP}
NM_CONTROLLED=no
ONBOOT=yes
TYPE=Ethernet
*ETH1 : *
BOOTPROTO=none
BROADCAST={PUBLIC BROADCAST IP}
DEFROUTE=yes
DEVICE=eth1
GATEWAY={PUBLIC GATEWAY IP}
HWADDR=00:15:17:89:31:48
IPADDR={PUBLIC IP}
IPV4_FAILURE_FATAL=yes

NETMASK=255.255.255.224
NETWORK={PUBLIC NETWORK IP}
NM_CONTROLLED=no
ONBOOT=yes

*ETH1:XXX1 :* (all subinterfaces are on the same network but different
from the network of ETH0 and ETH1)
BOOTPROTO=none
DEVICE=eth1:XXX1
IPADDR={PUBLIC IP}
IPV4_FAILURE_FATAL=yes
IPV6INIT=no
NM_CONTROLLED=no
ONBOOT=yes
