Thanks for response. I agree with you and I am trying to share the technical info. But one thing is really not working as you mentioned and expected - configuration will work after boot also. No its not working !
It is only working as temporary [setting IP from CLI] and not working after boot. I am not sure of the reason but also found interface related error messages in dmesg. now after ifstatus I find all these showing down [below]!
I see that there are a few problems that need to be addressed, see my comments below:

Just for reference, here's the default content of /etc/sysconfig/network/ifcfg-lo:

# Loopback (lo) configuration 

"ifup lo" then should be able to start the interface, and it should come up during boot as well. If you don't see according messages in /var/log/boot.msg (look for "
Setting up loopback interface"), then check if the boot.localnet service might have been disabled ("chkconfig boot.localnet" - this should report "on").

This doesn't look like the actual output - I'm missing time stamps and especially size info

somehost:~ # ls -l /etc/sysconfig/network/ifcfg-lo 
-rw------- 1 root root 172 Jul 17 13:30 /etc/sysconfig/network/ifcfg-lo 
somehost:~ #
... but what's more important, I would have expected to see two more files, for eth4 and eth6 (the bonding slaves). These may have content similar to

NAME='Ethernet controller'
Your bond0 configuration file looks good to me. Interestingly, it carries no IP address - are you using it as the uplink for a linux bridge?

Does "ethtool eth7" report that a link was detected? It could be a cabling problem or the switch port, the latter i.e. might be admin-down.

firmware.sh[7650]: Cannot find firmware file 'intel-ucode/06-2d-07' -->may be as you mentioned wouldn't mind these too much, the system will try to bring up the network interfaces, once detected
