There are two gigabit NICs in the system. I did NOT bond them, but after installing the second, they act as if bonded. I didn't tweak or touch the configuration at all after the install of the send NIC. Before the install, I had used the GUI in Jessie to configure the original onboard NIC to have a static IP address and it worked fine.
Now the GUI seems to be weirdly reporting that while it sees both NICs, one is "disconnected" (see screen shot of that below if you care to look) even though I can see via my network SNMP monitoring software that both NICs are not only connected but are carrying traffic. (Screen shot below if you care to look.)
The
ip a command says there are two MAC address for Ethernet links but only one has an 'inet' line after it:
- link/ether 80:3f:5d:07:26:a2 brd ff:ff:ff:ff:ff:ff.
- link/ether b8:97:5a:15:27:e5 brd ff:ff:ff:ff:ff:ff
The GUI reports only 80:3f:5d:07:26:a2 as the MAC address
BUT the actual MAC addresses (as they are announced out to SMTP) for the two NICs are:
And that makes no sense as well.
Where do I look to see what is really happening with these NICs? Can I split them up from each other so one is used for a VM exclusively? I am just simply stumped.
Where is this real configuration coming from in the OS?
The
/etc/network/interfaces is only this. Not even an eth0 mentioned.
