[j-nsp] EX4100/EX4400 1GE autoneg issues on SFP+ ports

[Igor Shtanko]

One of the reason can be follow, Juniper for 1G interface has name ge-x/x/x and the name of 10G interface is xe-y/y/y. So, you need use different interface name for 1G and 10G interfaces in your configuration.

Shit, I figured as much.

In the lab I have just successfully tested Arista SFP-10G-RA-1G-LX (rate 
adapting transceivers, 10G on the electrical side and 1G on the optical 
side) and the link came up just fine. So that's an option for 
small-scale, but these transceivers are quite expensive. Haven't found 
them 3rd party yet.
