Can't set up ethernet on eth1 using nmcli


Hi,

I am trying to set up an Ethernet connection on eth1, but after a couple of days without figuring it out I decided to share my problems to end this frustration.

I am using nmcli to configure the network, but the only network I can connect is eth0, while eth1 is in the state "unavailable".

I would like to be able to use both eth0 and eth1 to connect to the network.

Here are some outputs about my setup.

nmcli dev
DEVICE TYPE STATE CONNECTION
eth0 ethernet connected eth0
eth1 ethernet unavailable --
lo loopback unmanaged --
sit0 sit unmanaged --


nmcli con
NAME UUID TYPE DEVICE
eth1 c6c01f9f-7aeb-4692-a6ad-a8deac60c302 802-3-ethernet --
eth0 2dd3121b-f8e9-4001-a4fa-40ab22efde60 802-3-ethernet eth0


ifconfig eth1
eth1 Link encap:Ethernet HWaddr A6:49:E6:88:20:3F
UP BROADCAST MULTICAST MTU:1500 Metric:1

ethtool eth1

drv probe link

When trying to start the connection "eth1", I get the error "Error: Connection activation failed: Connection 'eth1' is not available on the device eth1 at this time."

I would appreciate any help on this, as I am stuck at this problem.

It is not clear, do you want to bond two interfaces or they are on different subnets?

I suppose bonding the interfaces should be sufficient.
But eth1 is still unavailable, and I don't know what's wrong.

To bond successfully your switch has to support it.
