How to find out correct NIC to configure for an IP or vlan.


HI Admins...

I have 8 NIC's available on one of our Red hat Linux server. I want to configure a public/data IP on one of the NIC. How can I find out the correct NIC's to use to configure for that IP or that particular vlan?

I don't want to test each available individual NIC by configuring IP on it and all...

Let me know ...Thanks in advance.

Try to find which NIC is active and connected. You can check using ethtool command on each NIC. Example,

Code:
ethtool eth0
Whatever has "Link Detected :Yes", you can configure IP and test on them.

Thanks for the reply. But is there any other way to figure it out the vlan from these connected links ?

There are only 8 NICS...it took you longer to log in here and post that question, than it would have taken you to run ethtool and FIND OUT. Or run "ifconfig -a", and display their information.
