We've setup LACP (802.3ad) on our Juniper switch and a Linux host, connected to the switch with 3x 1Gbps links. We are able to download from multiple sources at a rate of 3 Gbps, but when uploading files to different destinations, we get a maximum of 1 Gbps. Interestingly, only 1 uplink appears to be used by the Linux host to upload (to different destinations) :
Interface: ge-0/0/34, Enabled, Link is Up
Encapsulation: Ethernet, Speed: 1000mbps
Traffic statistics:
Input bytes: 9874189047641 (981736896 bps)
Output bytes: 5641687864781 (440210816 bps)
Interface: ge-0/0/36, Enabled, Link is Up
Encapsulation: Ethernet, Speed: 1000mbps
Traffic statistics:
Input bytes: 6194266205 (1016 bps)
Output bytes: 5368956712475 (400087456 bps)
Interface: ge-0/0/44, Enabled, Link is Up
Encapsulation: Ethernet, Speed: 1000mbps
Traffic statistics:
Input bytes: 1494878289802 (1016 bps)
Output bytes: 11897014259103 (469673216 bps)
Input and output are flipped over.
We basically followed this tutorial : http://phreek.org/blog/2014/11/centos-7-lacp-network-bonding
And setup LACP as usual on our switch.

Any idea?
