how to find out which eth0 or eth1 does card belongs

g_paschoal · 06-15-2011, 11:34 AM

I have in my ubuntu 3 eth?
eth0
eth1
eth2

just eth1 has an IP address...

I just have remote access to the server via ssh.

how do I find out which eth0 is a fiber nic ? Because I know one of them are.. but I cannot assign any IP address to them..

blabla@xxxxxx:/etc/network$ lspci |grep Ethernet
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)
07:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5708 Gigabit Ethernet (rev 12)
0a:00.0 Ethernet controller: Intel Corporation 82572EI Gigabit Ethernet Controller (Fiber) (rev 06)

which eth? belongs to this fiber nic ?

Thanks

Hi,

You already have the device ID's (03:00.0, 07:00.0 and 0a:00.0)

This will give you the ID's for eth0,1 and 2:

Code:

 udevinfo -a -p /sys/class/net/eth0 | grep -m1 ID
 udevinfo -a -p /sys/class/net/eth1 | grep -m1 ID
 udevinfo -a -p /sys/class/net/eth2 | grep -m1 ID

Hope this helps.

Command udevinfo is not valid...

need to install it?

Nope. In recent udev releases udevinfo has been replaced with udevadm info, so that the commands should be:

Code:

udevadm info -a -p /sys/class/net/eth0 | grep -m1 ID
udevadm info -a -p /sys/class/net/eth1 | grep -m1 ID
udevadm info -a -p /sys/class/net/eth2 | grep -m1 ID

@colucix: Thanks for providing the equivalent/current command!
