Hi Raymundo,
Sorry for wrong input, actually there are 3 NIC cards. 2 are inbuilt & 1
is external NIC card. Apart from 3 NIC one is 1000 GB speed, now I am in
big confusion that which one is high speed card. As u told I done
samething but while booting up got a message that there is no such
device so couldn't be able to make it up and reverted back the
modifications which I done. Just I am pasting output of ifconfig -a
[root@oldcav root]# ifconfig -a|more
eth0 Link encap:Ethernet HWaddr 00:E0:81:20:E7:2C

And out of dmesg|grep eth is
[root@oldcav root]# dmesg|grep eth
eth0: Intel Corporation 82557 [Ethernet Pro 100], 00:E0:81:20:E7:2C, IRQ
11.
eth1: Intel Corporation 82557 [Ethernet Pro 100] (#2),
00:E0:81:20:E7:2D, IRQ 10.
eth2: Mem:0xf6600000 IRQ:11 Speed:N/A Duplex:N/A
It seems 2 cards using same IRQ so how to identify which one is High
speed card & swap the IP address for same. Even it is ok to disable
other 2 cards..
My intention is to configure present IP address with High speed card..
Please direct me towards right thing..
Thanks & Regds,
Santosh..

dmesg | grep eth
this should show the cards detected at boot time.
the file /etc/modules.conf has the map from the ethx to hardware
and finally if you want to move the confiuration from eth0 to eth1 then
as superuser:
- edit /etc/static-routes if it exists and change the device
from eth0 to eth1
- go to /etc/sysconfig/network-scripts and rename ifcfg-eth0 to
ifcfg-eth1
- edit ifcfg-eth1 and change the device from eth0 to eth1 and
change any parameter you need
reboot
Do all this from the console, then after reboot ping first your nic and
then ping any host in your network
Good luck
