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 inet addr:192.168.3.16 Bcast:192.168.3.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:250 errors:0 dropped:0 overruns:0 frame:0 TX packets:170 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:26376 (25.7 Kb) TX bytes:15563 (15.1 Kb) Interrupt:11 Base address:0xf000

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 raymundo santosh kumar wrote: > Hi, > > > > I have 2 NIC card server .
