We will add 1 * 100 G with the exchange point LINX EXTREME.
The current port is not configured on a port-channel, we will filter all BGP sessions on this exchange before passing the new 100G production.
This maintenance is scheduled at 01:00 CEST.
Following this maintenance we will have 2 * 100G with the exchange point LINX EXTREME.
Update(s):
Date: 2016-04-28 17:19:41 UTC After investigation, this time the trouble comes from LINX side configuration.
The port-channel is up for 5 minutes now.
Traffic flows properly and no CRC is detected:

Date: 2016-04-28 17:17:24 UTC We just updated ldn-1-n7 to correct the BUG on LACP: task 17753
3rd try to add the second 100G in the port-channel: We believe in it !! :)
Date: 2016-04-28 17:14:08 UTC We have reproduced the problem.
The 2 ports are mounted for a few minutes then the LACP negotiation stopped working.
We took the catch packets on the port-channel and other control output for LACP.
We will continue troubleshooting with cisco tomorrow.
Date: 2016-04-28 17:11:53 UTC Second trial! We have implemented a span to troubleshoot if the problem recurs.
Date: 2016-04-28 17:10:28 UTC We have detected LACP negotiation problems and ports are suspended after the expiry of LACP Timeout.
LINX will attempt to reproduce the problem in a lab on their side.
We handed traffic 1 * 100 G without using port-channel.
Date: 2016-04-28 17:09:15 UTC The exchange point is isolated, we will now proceed with the establishment of two 100G ports in the same LAG.
Date: 2016-04-28 17:07:59 UTC We are isolating the exchange point LINX EXTREME in order to proceed with the upgrade.
