check in BIOS whether the NIC cards are activated.
An error caused due to eth0 and eth1 was disabled in BIOS instead they used to use Fibre optic device. So the fibre optic device is enabled and eth0 and eth1 are disabled.
It would help to resolve the issue 99%
Are you posting a question here, or is this supposed to be a 'tutorial'??? If so, it's incorrect, and omits a LOT of details. For example:
- Running "ifconfig" only will show you the activated interfaces. If there's one that's NOT activated, this step is pointless.
- What, exactly, is the "setup" command? Which version of Linux do you run "setup" on??? There are SPECIFIC network setup tools, but none are called "setup"
- Again, "eth0,eth1, eth2 activate" does nothing, and isn't a valid command. The activate command isn't for network interfaces, and if you mean you just want to TRY to activate them, you do it with the ifconfig command.
- Restarting network services after you've done the above won't accomplish anything, since you've not actually DONE anything yet.
- Why run ethtool at all, since the configs you want are done with the ifconfig command?
- The mii-tool command is deprecated, and not used much on current distros.
The only thing that will have an effect, is enabling the device in BIOS. Amazingly, that will then cause it to show up as an interface, have the appropriate module loaded, and then be ready to be configured. The 'tutorial' you've posted is incorrect and misleading. Also, you leave out which version/distro of Linux this supposedly applies to, what commands you're supposed to type in, and what output you should get.
